——再生聚四氟乙烯应用、等级、性能、颜色与市场全参考（含2026-09-11报价单样本及副牌/一级口径说明）
1 概述
1.1 什么是PTFE
PTFE（Polytetrafluoroethylene，聚四氟乙烯），商品名Teflon（特氟龙），由四氟乙烯（TFE）单体经自由基聚合得到，CAS号9002-84-0 / 31692-93-0。化学结构式为—(CF₂—CF₂)ₙ—，主链碳上的价键全部被氟原子包围，形成致密的氟原子外壳；碳氟键（C—F）键能约485 kJ/mol，属于已知较强的碳-卤素键之一。【网络查证】
PTFE分子量通常在10⁶–10⁷量级，熔体黏度高达10¹⁰–10¹¹ Pa·s，即使在熔点以上流动性仍极差，不能像PP/ABS/PC那样熔融注塑——这是它与常见热塑性工程塑料根本的加工区别。密实制品一律采用冷压成型（室温预压）+高温烧结（360–380℃）工艺，二次加工依靠车削、旋切、压延。【行业惯例】
再生PTFE指对PTFE机加工屑料、模压边角料、废膜废带等进行异物剔除、破碎、清洗后重新冷压烧结（或经辐照制成微粉）得到的再加工料；因分子链在回收过程中断裂，强度与致密性较原生料下降，主要用于低应力、非密封、非高纯场景。【行业惯例】
1.2 核心价值
PTFE的工程价值集中在四点：耐几乎一切化学介质（除熔融碱金属、元素氟、三氟化氯等极少数强氟化剂外，不被强酸、强碱、强氧化剂与有机溶剂侵蚀，且不溶于已知溶剂）；对钢动摩擦系数约0.04–0.10，自润滑；连续使用温度−200～+260℃；介电常数约2.0–2.2、介电损耗极低。再生料省去TFE单体聚合成本，价格低于原生料，但需接受强度、孔隙率与蠕变性能的下降，选型时须按用途降级使用。【行业惯例/网络查证】
1.3 形态分类
PTFE树脂按聚合工艺与形态分为悬浮树脂、分散树脂等；下表汇总与加工、选型直接相关的四类形态。另有分散乳液（PTFE含量约60%，用于浸渍喷涂）与微粉（1–20μm，作添加剂不单独成型），未列入主表。【行业惯例/网络查证】
表 1 PTFE主要形态、加工方式与典型用途
| 形态 | 外观/粒径 | 加工方式 | 典型用途 |
|---|
| 悬浮树脂（模压用颗粒/细粉） | 白色颗粒/细粉，约100–800μm | 冷压预成型→烧结（模压、柱塞挤出） | 棒、板、管、垫片、密封件、车削膜坯料 |
| 分散树脂（细粉） | 白色细粉，原生0.2–0.5μm | 糊状挤出（加助挤剂）→拉伸→烧结 | 生料带、细管、ePTFE微孔膜、纤维 |
| 模压料（悬浮细粉配模压级） | 白色均匀粉料 | 室温冷压预成型→360–380℃烧结 | 模压坯料、棒板管、密封垫片 |
| 车削膜（二次加工制品） | 乳白色半透明薄膜/带 | 烧结棒/板经车削、旋切、压延 | 车削薄膜、密封带、绝缘衬带 |
2 应用领域与具体产品
PTFE的耐化学、低摩擦、宽温与低介电特性决定了它主要服务于化工防腐、机械密封、电子电气与半导体等高可靠场景；再生料因强度与致密性下降，通常只进入其中对性能要求较低的部位。【行业惯例/网络查证】
2.1 化工防腐
化工防腐是PTFE的传统主战场，取其耐一切化学介质、不老化、不被溶剂侵蚀。
表 2 化工防腐领域具体产品与选材特征
| 序号 | 具体产品 | PTFE价值点 / 选材特征 |
|---|
| 1 | 管道衬里 | 耐酸碱腐蚀，衬于钢/管内壁防渗透；高纯/长寿命场景宜用原生料 |
| 2 | 阀门衬里/密封 | 耐化学介质+低摩擦启闭；再生料不宜用于承压密封 |
| 3 | 泵体衬里/泵件 | 耐腐蚀、耐磨损；湿法化工泵关键件建议原生 |
| 4 | 储罐/反应釜衬里 | 大面积防腐内衬，要求孔隙率低、不渗透 |
| 5 | 密封垫片/膨胀节 | 耐介质+补偿热变形；再生料限非关键、非长期承压部位 |
2.2 机械与密封
机械方向取其极低摩擦系数与自润滑、耐磨，常用于无油润滑场合；再生料蠕变与耐磨下降，高载荷工况需谨慎。
表 3 机械与密封领域具体产品与选材特征
| 序号 | 具体产品 | PTFE价值点 / 选材特征 |
|---|
| 1 | 滑动轴承/轴套 | 对钢摩擦系数低、自润滑，免加油；可加青铜/玻纤填充增强 |
| 2 | 导向滑板/导轨 | 低摩擦、耐磨，用于工装与设备导轨面 |
| 3 | 活塞环/导向环 | 低摩擦、耐温；高寿命场合（如膨胀节）宜用高弯曲寿命牌号 |
| 4 | 机械密封/盘根 | 耐介质+低摩擦；再生料熔结性差，隔膜类密封不宜使用 |
2.3 电子电气 + 半导体
电子电气方向取其极低介电常数与损耗、宽温稳定；半导体方向额外要求超高纯、金属离子析出低（SEMI F57级），再生料因纯度与孔隙率问题不适用高纯场景。

4.2 原生与再生性能对比
再生PTFE因分子链在回收中断裂、颗粒较难压密，拉伸强度较原生下降约40%–60%（降至约8–18 MPa），断裂伸长率、致密性与耐磨同步下降。【网络查证】
表 8 原生PTFE与再生PTFE性能变化（典型值）
| 性能指标 | 原生PTFE | 再生PTFE（传统粉碎再烧结） |
|---|
| 拉伸强度 | 20–35 MPa | 8–18 MPa（降幅约40–60%） |

待核实：2026年9月国内大宗实时吨价需以当日市场报价（百川盈孚/卓创等）复核，本表引用国际站挂牌与报价单样本，非国内现货成交吨价。【待核实】
6.4 政策法规
FDA食品接触：21 CFR 177.1550《Perfluorocarbon resins（全氟碳树脂）》为PTFE食品接触条款，覆盖TFE均聚物及TFE与HFP/PAVE等共聚物；再生PTFE因纯度、杂质与分子量降解，通常不符合FDA食品接触要求，条款原则上只适用于原生纯PTFE。【网络查证】
PFAS监管：欧盟REACH PFAS全面限制提案2023年由德、荷、丹、挪、瑞五国提交；2026年3月ECHA风险评估委员会（RAC）与社会经济分析委员会（SEAC）均支持欧盟范围内全面限制并设针对性豁免；2025年8月更新提案新增8个评估行业、78条豁免条款，工业类最长豁免期23.5年，而消费类炊具（含PTFE涂层）不享受豁免。预计2027年欧盟委员会提出限制草案，2027–2028年法规生效。3M已于2025年底完成全部PFAS生产退出，Dyneon GmbH于2026年被瑞士Capmont收购。【网络查证】
其他认证：PTFE阻燃达UL94 V-0（LOI≥90%，自熄不燃）；RoHS/REACH方面PTFE聚合物本身受限小分子单体/助剂需注册；半导体湿法高纯塑料金属离子析出执行SEMI F57。【行业惯例/网络查证】
6.5 减排数据
目前尚无公开权威、PTFE专属的全生命周期（LCA）碳足迹专项数据，不宜套用通用工程塑料或其他品种的减排比例。可定性表述：回收机加工屑料再烧结省去TFE单体聚合环节的能耗与原料投入，但再生性能降级使部分应用回到原生料，实际减排效益需结合具体替代比例与应用场景测算。【行业惯例/待核实】
6.6 东南亚进口渠道与料源背景
越南、泰国、马来西亚、印尼、菲律宾电子代工厂与化工产业集中，产生含氟废料（电子厂PTFE绝缘件、化工厂密封件/衬里、半导体/PCB废料），可通过本地废塑料贸易商归集，经RCEP项下通道回流中国（相关塑料废碎料关税安排需按具体HS编码逐项核实原产地规则）。泰国自2018年6月起收紧电子废物与废料进口，马来西亚回收名录接收料以PP/HDPE/ABS/PET/PS为主，未见PTFE专项接收厂。【网络查证/待核实】
风险与待核实：东南亚PTFE废料常与FEP/PFA/PVDF或填充PTFE混杂，分选难度大；受巴塞尔公约与RCEP再生原料口径影响；公开贸易统计中无PTFE废料专项编码数据，货量、纯度与关税需按HS 3904.61等逐项核实，并以实地/贸易商渠道确认。【待核实】

1 Overview
1.1 What is PTFE
PTFE (Polytetrafluoroethylene), trade name Teflon, is obtained by the free radical polymerization of tetrafluoroethylene (TFE) monomers, with CAS numbers 9002-84-0 / 31692-93-0. Its chemical structure is —(CF₂—CF₂)ₙ—, where all the valence bonds of the carbon atoms in the main chain are surrounded by fluorine atoms, forming a dense fluorine atom shell; the carbon-fluorine bond (C—F) has a bond energy of about 485 kJ/mol, which is one of the stronger known carbon-halogen bonds. [Network verified]
The molecular weight of PTFE is usually in the range of 10⁶–10⁷, and its melt viscosity can reach 10¹⁰–10¹¹ Pa·s. Even above its melting point, its fluidity remains extremely poor and it cannot be melt-injection molded like PP/ABS/PC—that is the fundamental processing difference between it and common thermoplastic engineering plastics. Solid products are all manufactured using cold pressing (room temperature pre-press) and high-temperature sintering (360–380°C) processes, with secondary processing relying on turning, lathe cutting, or calendaring. [Industry Practice]
Recycled PTFE refers to reprocessed material obtained by removing foreign objects, crushing, and cleaning PTFE machining scraps, molding edge scraps, waste films, and tapes, followed by cold pressing and sintering again (or being irradiated to produce fine powder); due to the breakage of molecular chains during the recycling process, its strength and density are lower than that of virgin material, and it is mainly used in low-stress, non-sealing, and non-high-purity scenarios. [Industry Practice]
1.2 Core Values
The engineering value of PTFE is concentrated in four points: resistance to almost all chemical media (except for a very few strong fluorinating agents such as molten alkali metals, elemental fluorine, and chlorine trifluoride; it is not corroded by strong acids, strong bases, strong oxidizers, or organic solvents, and is insoluble in known solvents); a dynamic friction coefficient against steel of about 0.04–0.10, self-lubricating; continuous operating temperature of −200 to 260°C; dielectric constant of about 2.0–2.2 with extremely low dielectric loss. Recycled material saves the cost of TFE monomer polymerization and is priced lower than virgin material, but requires acceptance of reduced strength, porosity, and creep performance, and should be downgraded according to use when selecting material. [Industry practice/Internet verification]
1.3 Morphological Classification
PTFE resin is divided into suspension resin, dispersion resin, etc., according to polymerization process and form; the table below summarizes four forms directly related to processing and selection. In addition, there are dispersion emulsions (PTFE content about 60%, used for impregnation and spraying) and fine powders (1–20 μm, used as additives and not molded separately), which are not included in the main table. [Industry practice/online verification]
Table 1 Main forms, processing methods, and typical applications of PTFE
| Form | Appearance/Particle Size | Processing method | Typical uses |
|---|
| Suspension resin (pellets/fine powder for molding) | White granules/fine powder, about 100–800 μm | Cold pressing preforming → sintering (molding, plunger extrusion) | Rods, plates, tubes, gaskets, seals, turned film blanks |
| Dispersed resin (fine powder) | White fine powder, primary particle size 0.2–0.5 μm | Paste extrusion (with extrusion aide) → stretching → sintering | Raw tape, small tube, ePTFE microporous membrane, fiber |
| Molding compound (suspension fine powder for molding grade) | White uniform powder | Room temperature cold pressing preforming → 360–380℃ sintering | Molded blanks, rods, plates, tubes, sealing gaskets |
| Turned film (secondary processed product) | Milky white semi-transparent film/strip | Sintered rods/plates after turning, peeling, and rolling | Turning films, sealing tapes, insulation liners |
2 Application Areas and Specific Products
The chemical resistance, low friction, wide temperature range, and low dielectric properties of PTFE determine that it is mainly used in high-reliability scenarios such as chemical corrosion protection, mechanical sealing, electronics and electrical, and semiconductors; recycled material, due to reduced strength and density, usually only enters parts where performance requirements are relatively low. [Industry practices/online verification]
2.1 Chemical Industry Corrosion Protection
Chemical anticorrosion is the traditional main battlefield of PTFE, chosen for its resistance to all chemical media, non-aging, and not being eroded by solvents.
Table 2 Specific Products and Material Selection Characteristics in the Chemical Anti-Corrosion Field
| Serial Number | Specific product | PTFE Value Points / Material Selection Features |
|---|
| One | Pipeline lining | Resistant to acid and alkali corrosion, lined on the inner wall of steel/pipes to prevent penetration; for high-purity/long-life scenarios, it is advisable to use virgin materials |
| Two | Valve lining/seal | Resistant to chemical media, low-friction opening and closing; recycled materials are not suitable for pressure sealing |
| Three | Pump body lining / pump parts | Corrosion-resistant and wear-resistant; key parts of wet chemical pumps are recommended to be made from primary materials |
| Four | Tank/Reactor Lining | Large-area anti-corrosion lining, requiring low porosity and impermeability |
| Five | Sealing Gasket/Expansion Joint | Resistant to media, compensates for thermal deformation; recycled material is limited to non-critical, non-long-term pressure-bearing parts |
2.2 Machinery and Sealing
Mechanical direction takes its extremely low friction coefficient along with self-lubrication and wear resistance, often used in oil-free lubrication scenarios; recycled material shows decreased creep and wear resistance, so high-load conditions should be approached with caution.
Table 3 Specific Products and Material Selection Characteristics in the Field of Machinery and Seals
| Serial Number | Specific product | PTFE Value Points / Material Selection Features |
|---|
| One | Sliding bearing / bushing | Has a low friction coefficient with steel, self-lubricating, no need for oil; can be reinforced with bronze/glass fiber filling |
| Two | Guide skateboard/guide rail | Low friction, wear-resistant, used for tooling and equipment guide surfaces |
| Three | Piston ring / Guide ring | Low friction, temperature resistant; for long-life applications (such as expansion joints), it is recommended to use grades with high bending fatigue life. |
| Four | Mechanical Seal / Packing | Medium-resistant, low friction; recycled material has poor fusibility, not suitable for diaphragm-type seals |
2.3 Electronics and Electricals Semiconductors
In the field of electronics and electrical engineering, it is chosen for its extremely low dielectric constant and loss, as well as wide temperature stability; in the field of semiconductors, there is the additional requirement of ultra-high purity and low metal ion precipitation (SEMI F57 grade). Recycled materials are not suitable for high-purity scenarios due to issues with purity and porosity.
Table 4 Specific Products and Material Selection Characteristics in the Electronics, Electrical, and Semiconductor Fields
| Serial Number | Specific product | PTFE Value Points / Material Selection Features |
|---|
| One | High-frequency insulation sleeve / wire insulation | Dielectric constant 2.0–2.2, loss <2×10⁻⁴, wide temperature stability |
| Two | PCB substrate (copper-clad laminate) | Low Dk/Df, beneficial for high-frequency high-speed signal integrity (emerging data centers/computing power) |
| Three | Antenna Cover / Radar Cover | Transparent to waves, resistant to high and low temperatures, lightweight |
| Four | High-purity wet process piping/valves/pumps | Low metal ion precipitation, resistant to high-purity chemical solutions; requires virgin semiconductor grade, recycled material is not suitable |
| Five | Cavity Liner/Polishing Pad | Chemical-resistant, high purity; semiconductor scenarios are sensitive to the porosity of recycled materials |
2.4 Medical Food Aerospace
This direction has high requirements for biocompatibility, compliance, and reliability: medical/food contact typically only accepts virgin pure PTFE (compliant with FDA 21 CFR 177.1550), and recycled materials generally do not meet food contact requirements.
Table 5 Specific Products and Material Selection Characteristics in the Fields of Medical, Food, and Aerospace
| Serial Number | Specific product | PTFE Value Points / Material Selection Features |
|---|
| One | Artificial vascular patch/surgical sutures | Biocompatible, non-stick, resistant to disinfection; must be made from medical-grade raw materials |
| Two | External drainage tube/implant | Disinfection-resistant, biocompatible; not suitable for recycled materials |
| Three | Cookware Coating / Food Equipment Sealing | Non-stick, heat-resistant, FDA-compliant; coatings for consumer cookware are under key PFAS regulatory scrutiny |
| Four | Aerospace hydraulic seals / wire insulation | Resistant to high and low temperatures, fuel-resistant, lightweight; select according to airborne specifications |
| Five | Fuel system components / Radome | Fuel-resistant, wave-permeable; regenerated materials limited to non-critical parts |
3 Industry Classification System
Recycled PTFE is currently categorized under GB/T 40006.1-2021 'Plastics — Recycled Plastics — Part 1: General Principles' — this series has published as of 2026 the Part 1 general principles and separate volumes for PE, PP, MPO, ABS, PS, PPE, etc., but there is no dedicated volume for PTFE, so recycled PTFE can only refer to the general principles. PTFE resin for molding has separate standards HG/T 2902-2024 'PTFE Resin for Molding' and HG/T 2903-2024 'Fine Powder PTFE Resin for Molding' (both effective on 2025-05-01); it should be noted that HG/T 2904-2024 is actually 'FEP Resin' (fluorinated ethylene propylene), not a PTFE standard.

4 Performance Indicators
4.1 Typical Properties of Virgin PTFE
The table below shows the industry-standard typical ranges for virgin pure PTFE, compiled from multiple manufacturers' TDS; differences exist among different grades and testing thicknesses. [Verified online]
Table 7 Typical Performance Values of Virgin PTFE (Compiled from Multiple TDS)
| Performance items | Typical value | unit | Remarks |
|---|
| Tensile Strength | 20–35 (commonly 25–30) | MPa | — |
| Elongation at break | 200–400 (>260) | % | — |
| Bending strength | About 20–28 | MPa | — |
| Notch impact strength | About 2.0 | kJ/m² | Higher without gaps |
| Coefficient of kinetic friction (for steel) | 0.04–0.10 | — | Self-lubricating |
| Dielectric constant (1 MHz) | 2.0–2.2 | — | Low dielectric |
| Dielectric loss factor (1 MHz) | <0.0002 | — | approximately 2 × 10⁻⁴ |
| Dielectric Strength (Breakdown) | 40–60 (for films it can reach 60–170) | kV/mm | Thickness material is relatively low |
| Volume resistivity | >10¹⁵～>10¹⁸ | Ω·cm | — |
| Continuous use temperature | −200 to 260 | °C | Melting point approximately 327℃ |

| Water absorption rate (24h) | <0.01 to <0.05 | % | Extremely low |
| Limiting Oxygen Index (LOI) | ≥90 | % | Non-combustible |
4.2 Comparison of Native and Regenerative Performance
Recycled PTFE experiences about a 40%–60% reduction in tensile strength (down to approximately 8–18 MPa) compared to virgin PTFE due to molecular chain breakage during recycling and the difficulty of compacting the particles. Its elongation at break, density, and wear resistance decline simultaneously. [Online verification]
Table 8 Performance Changes of Virgin PTFE and Recycled PTFE (Typical Values)
| Performance indicators | Virgin PTFE | Recycled PTFE (conventional crushing and re-sintering) |
|---|
| Tensile strength | 20–35 MPa | 8–18 MPa (reduction of about 40–60%) |
| Elongation at break | 200–400% | 80–200% |
| Elastic modulus | 0.4–0.5 GPa | 0.7–1.1 GPa (increased crystallinity) |
| Porosity | <1% | About 2% (the granules are harder and harder to compress) |
| Coefficient of friction | 0.04–0.10 | Micron-level can be maintained at 0.05–0.08 |
| Creep-resistant / Wear-resistant | Good | The decline is significant, and creep is more severe under high loads |
| Dielectric properties | Excellent | Increased porosity leads to a decrease in insulation/breakdown resistance |
Note: After irradiation (10–15 megarads), the original blend/paste extrusion is controlled, and tensile strength can return to about 18–28 MPa (up to about 80% of the original). Typical defects of regenerated PTFE include easy cracking, high porosity, low density, rough surface, large creep deformation, and reduced wear resistance; it is not suitable for pump valve diaphragms and seals, long-term pressure gaskets, chemical linings requiring high permeation resistance, high-frequency insulation, or high-purity semiconductor/medical applications. [Verified online]
4.3 Mechanism of Recycling Reduction and Usage Boundaries
Table 9 Mechanism of Performance Decline and Usage Limits of Recycled PTFE
| Dimension of change | Manifestation and Causes After Regeneration |
|---|
| Molecular chain breakage | Crushing/thermal history causes molecular chains to break, tie-chains decrease, and tensile strength drops to 8–18 MPa |
| Increased crystallinity / increased modulus | The polymer chains are regularly rearranged, increasing the elastic modulus to 0.7–1.1 GPa, but toughness decreases |
| Reduced fusibility | The bonding between particles deteriorates, making it prone to cracking and the appearance of micropores, with a porosity of about 2%. |
| Compactness/Density | The particles are relatively hard and difficult to compact, resulting in low density and increased surface roughness. |
| Creep and Wear Resistance | Creep is more pronounced under high loads, and wear resistance decreases |
| Dielectric properties | An increase in porosity introduces air, reducing insulation and breakdown resistance. |
| Use border | Limited to low-stress, non-sealed, non-high-purity, non-long-life conditions; food/medical/semiconductor grade must use virgin materials |
4.4 Classification by Use and Form
Table 10 Performance/Processing Characteristics Classified by Use and Form
| Classification Direction | Typical specifications | Performance/Processing Characteristics | Typical applications |
|---|
| Molded grade (suspended fine powder) | DF-203, M-12/M-18, 7A X | Cold pressing, sintering at 360–380°C, and turning after forming | Strip bars, gaskets, sealing components, turned films |
| Plunger extrusion stage (suspended medium particles) | DF-101/102/106 | Continuous extrusion of rods/pipes, dimensionally stable | Bars, pipes, profiles |
| Putty extrusion grade (dispersed resin) | CGF218, DE141/DE241 | Add binder paste extrusion → stretching → sintering | Raw tape, fine tube, ePTFE membrane |
| Coating/Impregnation Grade (Dispersed Emulsion) | About 60% solid content aqueous dispersion | Impregnation/Spray Coating/Casting Film Formation | Coating, glass cloth impregnation |
| Additive grade (irradiated micro-powder) | 1–20 μm | Does not form independently, used as a lubricant/modification additive | Lubricating oil, ink, coating, plastic modification |
| Fill-modified grade | Carbon black / Glass fiber / Bronze / MoS₂ | Improve wear resistance, rigidity, thermal conductivity, or electrical conductivity | Bearings, skateboards, conductive parts |
5 Color System
Virgin PTFE naturally ranges from milky white to semi-transparent waxy, while powdered material is white; black is mostly modified with carbon black/graphite/carbon fiber for conductivity, wear resistance, and anti-static purposes; there are also bronze (copper powder filled), brown (glass fiber filled), green (glass fiber with molybdenum disulfide) and other filled colors. After recycling: pure clean scrap remains white/slightly yellow, but the color uniformity is not as good as virgin material; mixed with fillers or old parts, it turns gray, dark, or yellowish; with multiple recycling and long thermal history, the color darkens (yellow-brown to dark gray) and transparency decreases. [Industry Practice]
Sample Description: The quotation sample on which this data is based does not indicate color. The color system is based on industry conventions and is not used for statistical inference.
Table 11 PTFE Color System and Grade Orientation
| Color/Grade | Native performance | Changes after regeneration | Usage tendency |
|---|
| Natural white / Slightly yellow | Milky to semi-transparent waxy | Clean scrap material recycled remains white/slightly yellow, with a slight decrease in uniformity | General molding, insulation, lining |
| black | Carbon black/graphite/carbon fiber filling | After mixing in old parts, the color becomes gray and the consistency is poor | Conductive, wear-resistant, anti-static parts |
| Filling color (bronze/tan/green, etc.) | Filled with copper powder/fiberglass/MoS₂ | Color darkens and dulls after multiple recolorings | Bearings, skateboards, and other wear-resistant structural components |
| Overall recycled material | — | High porosity, rough surface, uneven color | Low-stress non-critical parts, limited to non-sealed and non-high-purity |

6.2 Production Capacity Pattern
China's PTFE production capacity accounts for more than 60% of the global total, making it an important global supply base; by 2025, the domestic total production capacity is about 184,000 tons per year, with an actual output of about 152,000 tons, and an operating rate of about 82.6%. [Online verification]

| Domestic total | Approximately 184,000 tons per year (2025) | Production is about 152,000 tons, with an operating rate of about 82.6% |
Major overseas manufacturers: Chemours (Chemours / formerly DuPont's fluoroproduct business), Daikin, Solvay, AGC; Dyneon is currently under Switzerland's Capmont (Gendorf, Germany, about 18,000 tons/year). Note: Different research reports have varying figures for capacities of companies like Zhonghao Chenguang, and the specific numbers are subject to company announcements. [Verified online]
6.3 Price Comparison
Native domestic suspension bulk is approximately 30,000–60,000 yuan/ton (imported original factory brand is usually 30%–80% higher, and the price difference for superfine powder/dispersed emulsion is even greater); this batch of recycled secondary brand is about 45,000 yuan/ton. The price of recycled material has approached the low end of domestic native suspension, indicating that the current native PTFE price is relatively high due to fluorochemical quota and supply constraints, and the cost-performance window for recycled material has narrowed. [Online verification/industry practice]
Table 14 Comparison of Prices Between Virgin and Recycled PTFE (as of September 2026)
| Project | Native domestic floating bulk | Recycled PTFE sample | Explanation |
|---|
| Price (Yuan/ton) | Approximately 30,000–60,000 | About 45,000 | Recycled by-product 45,000 yuan/ton × 10 tons (2026-09-11) |
| Relative relationship | The low position is approaching the regeneration price | Higher than native but lower | The price spread window has narrowed compared to before |
| Causes of the narrowing of the spread window | Native fluoride chemical production is constrained by quotas/supply at a high level | Regeneration eliminates aggregation costs but performance degrades | Recycled material is only used for low-stress/non-sealed/non-high-purity scenarios |
To be verified: The real-time domestic bulk ton price in September 2026 needs to be cross-checked with the market quotation on the day (BaiChuan YingFu/ZhuoChuang, etc.). This table cites the listing and quotation samples from the international station and is not the domestic spot transaction ton price. [To be verified]
6.4 Policies and Regulations
FDA Food Contact: 21 CFR 177.1550 "Perfluorocarbon Resins" is the PTFE food contact regulation, covering TFE homopolymers and copolymers of TFE with HFP/PAVE, etc.; regenerated PTFE usually does not meet FDA food contact requirements due to decreased purity, impurities, and molecular weight degradation, and the regulation in principle only applies to virgin pure PTFE. [Online verification]
PFAS Regulation: The EU REACH comprehensive PFAS restriction proposal was submitted in 2023 by Germany, the Netherlands, Denmark, Norway, and Sweden; in March 2026, both the ECHA Risk Assessment Committee (RAC) and the Socio-Economic Analysis Committee (SEAC) supported an EU-wide full restriction with targeted exemptions; in August 2025, the updated proposal added 8 assessed industries and 78 exemption clauses, with the longest exemption period for the industrial sector being 23.5 years, while consumer cookware (including PTFE-coated) is not eligible for exemptions. The EU Commission is expected to propose the restriction draft in 2027, with the regulation expected to take effect in 2027–2028. 3M had completed its entire PFAS production phase-out by the end of 2025, and Dyneon GmbH was acquired by Swiss company Capmont in 2026. [Verified online]
Other certifications: PTFE flame retardant meets UL94 V-0 (LOI ≥ 90%, self-extinguishing and non-flammable); in terms of RoHS/REACH, PTFE polymer itself requires registration for restricted small molecule monomers/additives; for semiconductor wet-process high-purity plastics, the leaching of metal ions is performed according to SEMI F57. [Industry practice/online verification]
6.5 Emission Reduction Data
Currently, there is no publicly available authoritative, PTFE-specific full life cycle (LCA) carbon footprint data, and it is not appropriate to apply the emission reduction ratios of general engineering plastics or other types. A qualitative statement can be made: recycling machined scrap material and re-sintering avoids the energy consumption and raw material input of the TFE monomer polymerization process, but performance degradation of the recycled material causes some applications to revert to using virgin material. The actual emission reduction benefit needs to be calculated based on the specific substitution ratio and application scenario. [Industry practice / to be verified]
6.6 Southeast Asia Import Channels and Material Source Background
Electronic contract manufacturers and chemical industries are concentrated in Vietnam, Thailand, Malaysia, Indonesia, and the Philippines, producing fluorine-containing waste (PTFE insulation parts from electronics factories, seals/linings from chemical plants, semiconductor/PCB waste). These can be collected through local plastic waste traders and returned to China via channels under the RCEP (the relevant plastic waste tariff arrangements need to be verified item by item according to the specific HS code and origin rules). Since June 2018, Thailand has tightened imports of electronic waste and scrap, while Malaysia's recycling catalog mainly accepts PP/HDPE/ABS/PET/PS materials, and no PTFE-specific receiving plants have been found. [Online verification/to be confirmed]
Risks and to be verified: PTFE waste in Southeast Asia is often mixed with FEP/PFA/PVDF or filled PTFE, making sorting difficult; it is affected by the Basel Convention and RCEP standards for recycled materials; there is no specific code for PTFE waste in public trade statistics, so quantity, purity, and tariffs need to be verified item by item according to HS 3904.61, and confirmed through on-site inspections or trader channels.
