——再生聚苯醚应用、等级、性能与颜色全参考（含2026-09-11报价单样本数据及PPO/PPE命名对照）
1 概述
1.1 什么是再生PPO
PPO（Polyphenylene Oxide，聚苯醚）与PPE（Polyphenylene Ether，聚亚苯基醚）指同一种材料：美国及杜邦-Noryl体系习惯称PPO，日本及国标学术界习惯称PPE。二者为同一物，仅命名习惯不同，本报告按行业通称写作“PPO/PPE”。
纯PPO为非结晶性热塑性特种工程塑料，玻璃化转变温度Tg约210–211℃，密度约1.06 g/cm³（工程塑料中比重较轻者之一），吸水率极低（约0.06%–0.07%，五大工程塑料中较低），介电常数约2.5–2.8（工程塑料中较小档），宽温宽频下介电损耗极小。纯料加工困难，市售95%以上为改性PPO（MPPO/MPPE），主流为PPO/PS（PPE+HIPS）合金；另有PPO/PA、PPO/PBT、玻纤增强（10%/15%/20%/30%）、导电抗静电及矿物低翘曲等改性方向。PPO/PS合金熔体加工温度约260–300℃，标准MFR测试条件为280℃/5kg。
再生PPO（rPPO/rPPE）按料源分两类：PIR（Post-Industrial Recycling）来自汽车/电子厂水口料、工业水口料；PCR（Post-Consumer Recycling）来自电子电器拆解外壳、家电拆解料、汽车报废件。常规回收流程为破碎→分选→清洗→干燥→（挤出）造粒。需注意：国标明确再生PPE不适用于医疗废物、农药包装等危险废物及放射性废物，也不用于食品接触材料。
1.2 核心价值
成本端：再生PPO主流成交区间约1.5万–2.35万元/吨（2026-09-11报价单口径），原生改性MPPO市场口径约2万–4万元/吨，再生料较原生低约30%–50%，对成本敏感的结构件具备替代空间。
减排端：PPO原生合成工艺复杂、能耗高，机械再生省去单体合成环节，减排与降耗方向成立；可参照工程塑料行业标杆量级（如SABIC循环聚合物先进回收路线约省2 kg CO₂/kg，聚烯烃口径，不可直接套用PPO）。PPO专属LCA数值待专门报告出具。
政策端：欧盟新ELV法规(EU) 2026/1738已落地，要求新车塑料中消费后再生塑料占比2032年9月起≥15%、2036年9月起≥25%，且其中至少20%须来自报废车辆闭环回收，仅认可消费后废料——这是再生PPO进入汽车供应链的核心政策驱动。
1.3 重要区分：两个“PPO”市场不可混用
本报告对象为改性MPPO工程塑料及其再生料（汽车/电子/水处理结构件，PPO/PS合金为主）。市场上另有一类高频高速PCB/CCL用电子级线性PPO树脂（M8级，2026年现货价约50–70万元/吨），属涂料/覆铜板原料市场。二者虽同称PPO，但分子量形态、纯度要求、价格量级与下游应用完全不同，数据不可混用。选型或报价时须先确认对象是“改性工程塑料MPPO”还是“电子级线性PPO树脂”。

4 性能指标
4.1 原生与再生对比
原生改性PPO（以SABIC Noryl为代表）典型性能见表6。
表6 原生改性PPO典型性能指标（TDS口径）
| 指标 | 典型数值 | 来源/条件 |
|---|
| 密度 | 1.06–1.08 g/cm³ | SABIC/TDS |
| 玻璃化转变温度Tg | 约210–211℃ | 非结晶 |
| 吸水率 | 0.06%–0.07%（极低） | 五大工程塑料较低 |

| 介电常数 | 2.5–2.8 | 工程塑料较低档 |
| 加工温度 | 260–300℃ | PPO/PS合金熔体 |
| MFR测试条件 | 280℃/5kg | GB/T 3682.1 |
再生PPO的国标底线要求与实测验证样品数据见表7。
表7 国标GB/T 40006.13再生PPE+HIPS(REC)底线与实测验证值
| 指标 | 国标GB/T 40006.13底线 | 实测验证值（黑色） | 说明 |
|---|
| 密度 | 1.03–1.11 g/cm³ | — | 国标范围 |
| MFR(280℃/5kg) | 01组≤10 / 02组10–20 / 03组20–40 | — | g/10min |
| 灰分 | -01≤1% / -02≤5% | 0.06%–4.8% | 实测样品 |
| 拉伸强度 | -01≥35MPa / -02≥30MPa | 40–56 MPa | 实测达标 |

| 弯曲模量 | — | 约2100–2500 MPa | 实测 |
| 简支梁缺口冲击 | — | 约5.6–10.6 kJ/m² | 较原生GFN3偏低 |
再生降幅以定性为主：玻纤增强料经多次熔融后纤维长度缩短、长径比下降，导致模量/刚性略降、缺口冲击下降更明显；但学术研究表明阻燃型PPO/HIPS多次循环后IZOD冲击保持率优于同类PC/ABS。介电性能方面，因分子无强极性基团，循环后介电常数/损耗变化小（具体保留率待核实）。详见表8。
表8 再生PPO性能降幅定性对照
| 性能项 | 再生后变化（定性） | 说明 |
|---|
| 玻纤长度/长径比 | 下降 | 多次熔融挤出后纤维缩短 |
| 模量/刚性 | 略降 | 长径比下降所致 |
| 缺口冲击 | 下降较明显 | 但PPO/HIPS保持率优于PC/ABS |
| 介电常数/损耗 | 变化小 | 分子无强极性基团，保留率待核实 |
| 颜色 | 偏深、偏黄 | PS相热氧老化泛黄 |
| 阻燃性 | 基本保留 | 与HIPS共混后仍具自熄性 |
4.2 按用途与改性分级
成型用途决定流动性与熔体强度要求，改性方向决定刚性/导电/耐化学等附加性能。再生PPO选级时需同时对照两个维度，详见表9。
表9 再生PPO按用途与改性方向分级
| 分级方向 | 典型规格 | 性能/加工特点 | 典型应用 |
|---|
| 通用注塑 | PPO/PS（SE系列） | 阻燃、尺寸稳定 | 电子接插件、骨架 |
| 玻纤增强 | GFN2(20%GF)/GFN3(30%GF) | 高刚性、HDT约170℃档 | 散热风扇、BMS支架 |
| 耐油耐化学 | PPO/PA（GTX/XP） | 耐燃油、耐化学 | 汽车进气件、油杯 |
| 低翘曲 | 矿物填充 | 低翘曲、尺寸稳 | 精密结构件 |
| 导电/抗静电 | 碳黑/导电填充 | 防静电 | 服务器结构件 |
| 低吸水耐热水 | W系列（旭化成） | 耐热水、极低吸水 | 供水专用件 |
5 颜色体系
再生PPO颜色直接决定售价与定位。主流颜色以黑色为主（国标全部验证样品为黑色），其次灰色、米黄/琥珀色/本色。再生料相较原生本色料颜色偏深、偏黄，不影响基本力学性能。颜色与报价对应关系见表10。
表10 再生PPO颜色体系（含2026-09-11报价单价格）
| 颜色/品级 | 报价（元/吨） | 品级 | 特点 |
|---|
| 黑色·高温（高档） | 23,500 | 一级 | 黑色遮盖力强、来源广，此档疑品质/批次较高 |
| 黑色·高温（低档） | 15,500 | 一级 | ⚠同规格两档价差大，疑品质或批次差异，待核实 |
| 米黄·增强 | 15,000 | 一级 | 成分相对单一、可做中高端配色 |
| 灰色·高温增强(GFN2-780/高科) | 18,000 | 一级 | 加纤增强多对标GFN2，价格偏高 |
| 黑色·增强10% | 15,000 | 二级 | 工业级通货，品质偏低 |
| GFN2-801式/高科 | 20,000 | 一级 | 仿牌号20%GF高温款，价格居中偏高 |
为何黑色为主：①黑色遮盖力强——再生料来源杂、色差大，黑色可掩盖泛黄与杂色，最易通行；②黑色来源广——电子/汽车黑壳料量大，是再生PPO最主要料源。黑色因此品级较杂、价格跨度较大（报价单黑色高温1.55万–2.35万/吨两档并存）。米黄/本色料因成分相对单一、可做中高端配色，价格居中；灰色加纤增强多对标GFN2，价格偏高。
变色机理：PPO/PS合金加工温度高（260–300℃），反复熔融、残留水分与杂质、受阻酚/阻燃剂体系热氧老化，导致PS相降解泛黄、炭化着色。PPO燃烧鉴别特征为“收缩快、墨臭味略带苦味”，可用于分选时的外观辅助判断。
6 市场与趋势速览
6.1 产能与价格格局
产能（付费咨询报告口径，待核实）：2025年中国PPO（工程级改性）产量约13.7万吨；蓝星化工3.82万吨（约27.9%）、金发科技2.95万吨（约21.5%）、宁波利安1.68万吨（约12.3%）、山东浩霖0.92万吨（约6.7%）。2025年中国聚苯醚合金市场规模约42.3亿元（同比约+8.6%）；全球线性PPO树脂2025年约19.65亿美元。再生PPO年产量/消纳量未见权威公开统计——属小众特种工程塑料再生品种，国内仅少数头部企业建成闭环回收示范线，规模远小于PP/ABS等通用料，具体吨数待核实。
价格：原生改性MPPO工程塑料市场口径约2万–4万元/吨（随牌号/增强比波动大，待核实）；再生PPO综合报价区间约1.5万–2.35万元/吨。另有低端黑色PPO增强再生颗粒在1688挂牌低至约7700元/吨（工业级通货，品质低）。产能与再生贸易集散地集中于华东（宁波/苏州/东莞为贸易集散）、华南（东莞/深圳代理商集群）；再生贸易集散地为浙江余姚/慈溪、广东樟木头。

6.3 PPO/PPE命名对照
市场上PPO、PPE、MPPO、PPE(REC)、rPPO等叫法常被混用，选型或报价前须先对照，详见表12。
表12 PPO/PPE命名对照表
| 叫法 | 全称 | 备注 |
|---|
| PPO | Polyphenylene Oxide | 美国/杜邦-Noryl系习惯称呼 |
| PPE | Polyphenylene Ether | 日本/国标学术称呼，=PPO |
| MPPO/MPPE | 改性聚苯醚 | 市售主流，PPO/PS合金为主 |
| PPE(REC) | 再生聚苯醚 | GB/T 40006.13-2025命名 |
| rPPO/rPPE | 再生PPO | 行业俗称 |
6.4 政策法规
中国：GB/T 40006.13-2025（再生PPE专项，2026-02-01实施）+ GB/T 40006.1-2021通则。国内整车厂（比亚迪/蔚来/小鹏等）供应链对再生含量有ESG采购导向，但国家层面尚无强制再生料占比法规（待核实）。再生塑料颗粒进口需《再生塑料颗粒环保项目检测报告》、原料来源合法声明、MSDS、品质证书（MFR/灰分）。
欧盟（强驱动）：新ELV法规(EU) 2026/1738已落地——新车塑料中消费后再生塑料占比2032年9月起≥15%、2036年9月起≥25%，且其中至少20%须来自报废车辆闭环回收，仅认可消费后废料。WEEE、RoHS 2011/65/EU要求再生PPO管控多溴联苯PBB/PBDE、邻苯二甲酸酯等。
美国/日本：美国无联邦强制再生料占比法，以UL2809再生含量声明+品牌商采购要求为主；日本以家电回收法推进，PPO再生多为企业闭环（具体法规条文待核实）。
6.5 减排数据
PPO特有的“再生vs原生”精确碳减排百分比未检索到权威公开数值，标注待核实。可引用的行业级事实（非PPO特有，需注明口径）：SABIC推出PCR基Noryl产品组合，配方含25%以上PCR，其中NH5120RC3含30% PCR；同时推出全牌号ISCC PLUS认证生物基版本（300+牌号）。行业标杆LCA（SABIC认证循环聚合物，聚烯烃口径）：先进回收路线约省2 kg CO₂/kg——不可直接套用到PPO，仅作量级参考。定性结论：PPO原生合成工艺复杂、能耗高，机械再生省去单体合成环节，减排与降耗方向成立，但具体百分点/吨均能耗数据待PPO专属LCA报告出具。
6.6 东南亚进口渠道与料源背景
政策与贸易背景：中国“禁废令”后，废塑料货源向东南亚转移，中资企业在越/泰/马建厂后将再生颗粒回销国内。关税方面，东盟自贸协定/RCEP项下约90%以上产品零关税（需提供原产地证），另缴增值税；RCEP成员国原产货物可享协定税率。
各国特点（定性）：越南2024年废塑料造粒产能约68万吨（较2020年增近3倍），约65%由中资/中资控股运营，主供欧美日韩品牌再生含量需求，进口中国塑胶粒享0关税；泰国出台《国家塑料废弃物管理路线图(2022-2027)》，政策体系较完整；马来西亚曾承接大量对华废塑料转移，环保监管趋严后规范化；印尼/菲律宾为补充货源国。
对再生PPO的含义（定性）：再生PPO因属小众特种料，东南亚专项贸易数据未见公开，以上为再生工程塑料通用渠道框架；特种PPO东南亚来源以定性为主，PPO专属贸易量待核实。风险点：东南亚再生颗粒品质参差、易扣货；进口需标注“Recycled Plastic Granules”及来源、附环保检测报告。

——Comprehensive Reference for Recycled Polyphenylene Ether Applications, Grades, Performance, and Colors (Including Quotation Sample Data as of 2026-09-11 and PPO/PPE Naming Comparison)
1 Overview
1.1 What is Recycled PPO
PPO (Polyphenylene Oxide) and PPE (Polyphenylene Ether) refer to the same material: in the U.S. and the DuPont-Noryl system, it is commonly called PPO, while in Japan and the academic circles following national standards, it is referred to as PPE. They are the same substance, only named differently; in this report, it is written as "PPO/PPE" according to the industry's common usage.
Pure PPO is an amorphous thermoplastic specialty engineering plastic, with a glass transition temperature (Tg) of approximately 210–211°C, a density of about 1.06 g/cm³ (one of the lighter engineering plastics), very low water absorption (about 0.06%–0.07%, lower among the five major engineering plastics), a dielectric constant of around 2.5–2.8 (relatively low among engineering plastics), and extremely low dielectric loss over a wide temperature and frequency range. Processing of the pure material is difficult, and commercially over 95% is modified PPO (MPPO/MPPE), with the mainstream being PPO/PS (PPE HIPS) alloys; other modifications include PPO/PA, PPO/PBT, glass fiber reinforcement (10%/15%/20%/30%), conductive and anti-static, and mineral-based low warpage variants. The melt processing temperature of PPO/PS alloys is approximately 260–300°C, with standard MFR test conditions of 280°C/5kg.
Recycled PPO (rPPO/rPPE) is divided into two categories based on material source: PIR (Post-Industrial Recycling) comes from automotive/electronic factory sprue material and industrial sprues; PCR (Post-Consumer Recycling) comes from disassembled electronic and electrical housings, household appliance scrap, and end-of-life vehicles. The conventional recycling process is crushing → sorting → washing → drying → (extrusion) granulation. Please note: the national standard clearly states that recycled PPE is not suitable for hazardous wastes such as medical waste, pesticide packaging, or radioactive waste, and it is also not used for food contact materials.
1.2 Core Values
Cost side: The mainstream transaction range for recycled PPO is about 15,000–23,500 yuan/ton (as of the 2026-09-11 quotation), while the market range for virgin modified MPPO is about 20,000–40,000 yuan/ton. Recycled materials are about 30%–50% lower than virgin materials, providing substitution potential for cost-sensitive structural components.
Emission Reduction Aspect: The native PPO synthesis process is complex and energy-intensive. Mechanical recycling eliminates the monomer synthesis step, making emission reduction and energy saving feasible; reference can be made to benchmark levels in the engineering plastics industry (for example, SABIC's advanced recycling route for circular polymers saves about 2 kg CO₂/kg, in the context of polyolefins, and cannot be directly applied to PPO). PPO-specific LCA values will be provided in a dedicated report.
Policy side: The EU's new ELV regulation (EU) 2026/1738 has been implemented, requiring that from September 2032, at least 15% of plastics in new vehicles come from post-consumer recycled plastics, and from September 2036, at least 25%, with at least 20% of this specifically coming from closed-loop recycling of end-of-life vehicles. Only post-consumer waste is recognized—this is the core policy driver for recycled PPO to enter the automotive supply chain.
1.3 Important Distinction: The Two 'PPO' Markets Should Not Be Confused
This report focuses on modified MPPO engineering plastics and their recycled materials (mainly used in automotive/electronic/water treatment structural components, primarily PPO/PS alloys). There is another type on the market: electronic-grade linear PPO resin for high-frequency, high-speed PCBs/CCLs (M8 grade, spot price around 500,000–700,000 CNY/ton in 2026), which belongs to the coatings/copper-clad laminate raw material market. Although both are called PPO, their molecular weight form, purity requirements, price range, and downstream applications are completely different, and the data cannot be mixed. When selecting or quoting, it is necessary to first confirm whether the subject is 'modified engineering plastic MPPO' or 'electronic-grade linear PPO resin.'
2 Application Areas and Specific Products
According to the paid consultation report (to be verified), in the global modified MPPO downstream structure, electronics and electrical applications are the main segments, with automobiles accounting for about 32%–34%, industrial and water treatment about 16%, and office automation about 12%. The core material selection for recycled PPO focuses on: very low water absorption, dimensional stability, hydrolysis resistance, excellent dielectric properties, and the trend of natural flame retardancy and self-extinguishing.

3 Industry Classification System
Current Status of National Standard: GB/T 40006.13-2025 'Plastics — Recycled Plastics — Part 13: Polyphenylene Ether (PPE) Materials' was issued on 2025-08-01 and will be implemented on 2026-02-01, and is currently in effect (not the previously rumored 2023 version). Its scope applies to granular PPE (REC) made from waste polyphenylene ether/high-impact polystyrene alloys (PPE PS-I) as raw materials and processed through mechanical recycling. Classification and naming are as follows: PPE HIPS(REC)-B1-C-1,,M,01-01: divided into three groups by MFR (280℃/5kg) of 01/02/03 (corresponding to MFR ≤10 / 10–20 / 20–40 g/10min); each group is further divided into two grades: -01 (ash ≤1%) and -02 (ash ≤5%).
Industry-standard grading mainly unfolds from five dimensions: purity grade, molding application, modification direction, color, and grade designation system. See Table 5 for details.

4 Performance Indicators
4.1 Comparison of Native and Regenerated
The typical properties of virgin modified PPO (represented by SABIC Noryl) are shown in Table 6.
Table 6 Typical Performance Indicators of Virgin Modified PPO (TDS Caliber)
| Indicator | Typical value | Source/Condition |
|---|
| Density | 1.06–1.08 g/cm³ | SABIC/TDS |
| Glass transition temperature Tg | About 210–211°C | Non-crystalline |
| Water absorption rate | 0.06%–0.07% (extremely low) | The five major engineering plastics are relatively low |
| Tensile strength of pure material | 70–90 MPa | Changzhou Prowin |
| Unfilled modified PPE stretching | 55–70 MPa | nextgencomp |

| MFR Test Conditions | 280℃/5kg | GB/T 3682.1 |
The national standard baseline requirements for recycled PPO and the measured verification sample data are shown in Table 7.
Table 7 National Standard GB/T 40006.13 Recycled PPE HIPS (REC) Baseline and Measured Verification Values
| Indicator | National Standard GB/T 40006.13 baseline | Measured Verification Value (Black) | Explanation |
|---|
| Density | 1.03–1.11 g/cm³ | — | National Standard Range |
| MFR (280°C/5kg) | Group 01 ≤10 / Group 02 10–20 / Group 03 20–40 | — | g/10min |
| Ash content | -01 ≤ 1% / -02 ≤ 5% | 0.06%–4.8% | Tested sample |
| Tensile strength | -01≥35MPa / -02≥30MPa | 40–56 MPa | Tested and up to standard |
| Bending strength | -01≥60MPa / -02≥50MPa | 70–91 MPa | Tested and up to standard |
| Bending modulus | — | Approximately 2100–2500 MPa | Actual measurement |
| Notched simply supported beam impact | — | Approximately 5.6–10.6 kJ/m² | Lower than the original GFN3 |
The degradation in recycling is mainly qualitative: after multiple melt cycles, the length of glass fibers in reinforced materials shortens and the aspect ratio decreases, leading to a slight decline in modulus/stiffness and a more noticeable drop in notch impact strength; however, academic studies have shown that flame-retardant PPO/HIPS maintains a higher IZOD impact retention after multiple cycles compared to similar PC/ABS. In terms of dielectric properties, because the molecules do not have strongly polar groups, the dielectric constant/loss changes little after recycling (specific retention rates need to be verified). See Table 8 for details.
Table 8 Qualitative Comparison of Performance Degradation of Recycled PPO
| Performance items | Changes After Regeneration (Qualitative) | Explanation |
|---|
| Glass fiber length/length-to-diameter ratio | decline | Fiber shortening after multiple melt extrusions |
| Modulus / Rigidity | Slightly decrease | Caused by a decrease in the aspect ratio |
| Gap impact | The decline is quite significant | But the retention rate of PPO/HIPS is better than that of PC/ABS |
| Dielectric Constant/Loss | Small change | The molecule has no strongly polar groups, and the retention rate needs to be verified. |
| Color | Slightly dark, slightly yellow | PS thermo-oxidative aging yellowing |
| Flame retardancy | Basically preserved | Still self-extinguishing after blending with HIPS |
4.2 Classification by Use and Modification
The molding application determines the requirements for flowability and melt strength, while the direction of modification determines additional properties such as rigidity, conductivity, and chemical resistance. When selecting grades of recycled PPO, both dimensions need to be considered simultaneously, as detailed in Table 9.
Table 9 Classification of Recycled PPO by Application and Modification Direction
| Classification Direction | Typical specifications | Performance/Processing Characteristics | Typical applications |
|---|
| General injection molding | PPO/PS (SE Series) | Flame retardant, dimensionally stable | Electronic connectors, skeleton |
| Glass fiber reinforced | GFN2 (20% GF) / GFN3 (30% GF) | High rigidity, HDT around 170°C grade | Cooling fan, BMS bracket |
| Oil-resistant and chemical-resistant | PPO/PA (GTX/XP) | Fuel-resistant, chemical-resistant | Car intake components, oil cup |
| Low warpage | Mineral filling | Low warping, stable dimensions | Precision structural components |
| Conductive/Anti-static | Carbon Black / Conductive Filler | Anti-static | Server structural components |
| Low water absorption and heat-resistant | W Series (Asahi Kasei) | Heat-resistant, extremely low water absorption | Water supply special parts |
5 Color System
The color of recycled PPO directly determines the price and positioning. The mainstream color is mainly black (all samples verified according to the national standard are black), followed by gray, beige/amber/natural color. Compared with virgin natural color material, recycled material has a darker and more yellowish color, which does not affect the basic mechanical properties. The relationship between color and quotation is shown in Table 10.
Table 10 Recycled PPO Color System (Including Quotation Prices as of 2026-09-11)
| Color/Grade | Price quotation (CNY/ton) | Grade | Characteristics |
|---|
| Black · High Temperature (Premium) | 23,500 | Level 1 | Black has strong coverage and is widely sourced; this item is suspected to be of higher quality/batch. |
| Black · High Temperature (Low Gear) | 15,500 | Level 1 | ⚠ The price difference between the two tiers of the same specification is large, suspected quality or batch differences, to be verified |
| Beige · Enhanced | 15,000 | Level 1 | Relatively simple composition, can be used for mid-to-high-end color schemes |
| Gray·High-Temperature Enhancement (GFN2-780/High-Tech) | 18,000 | Level 1 | Glass fiber reinforced is mostly benchmarked against GFN2, with a relatively high price |
| Black · Enhanced 10% | 15,000 | Secondary | Industrial-grade currency, low quality |
| GFN2-801 Model / Gaoke | 20,000 | Level 1 | Imitation brand 20% GF high-temperature model, price is mid-to-high range |
Reasons for black being dominant: ① Strong coverage of black — recycled materials come from various sources with significant color differences, and black can cover yellowing and mixed colors, making it the easiest to use; ② Wide sources of black — electronic/car black shell materials are abundant and are the main source of recycled PPO. Therefore, black is of relatively mixed grades, with a wide price range (price list for black high-temperature material ranges from 15,500–23,500 RMB/ton, with two levels coexisting). Beige/natural-colored materials have relatively simple compositions and can be used for mid-to-high-end color matching, with moderate prices; gray fiber-reinforced materials are comparable to GFN2, with higher prices.
Color change mechanism: The processing temperature of PPO/PS alloy is high (260–300°C). Repeated melting, residual moisture and impurities, and the thermal-oxidative aging of the hindered phenol/flame retardant system lead to yellowing and carbonized coloration of the PS phase. The characteristic of PPO when burned is 'rapid shrinkage, with an inky smell slightly bitter,' which can be used as an auxiliary visual indicator during sorting.
6 Market and Trend Overview
6.1 Production Capacity and Price Pattern
Production capacity (according to paid consulting reports, to be verified): In 2025, China's PPO (engineering-grade modified) output is about 137,000 tons; Bluestar Chemical 38,200 tons (about 27.9%), Kingfa Technology 29,500 tons (about 21.5%), Ningbo Lian 16,800 tons (about 12.3%), Shandong Haolin 9,200 tons (about 6.7%). In 2025, the market size of China's polyphenylene ether alloys is about 4.23 billion yuan (year-on-year growth of about 8.6%); the global linear PPO resin in 2025 is about 1.965 billion USD. There is no authoritative public statistic for the annual output/consumption of recycled PPO—being a niche specialty engineering plastic recycled variety, only a few leading domestic companies have established closed-loop recycling demonstration lines, and the scale is much smaller than general-purpose materials such as PP/ABS, and the specific tonnage is to be verified.
Price: The market price of virgin modified MPPO engineering plastic is approximately 20,000–40,000 yuan/ton (varies greatly depending on grade/reinforcement ratio, to be verified); the comprehensive quotation range for recycled PPO is about 15,000–23,500 yuan/ton. Additionally, low-end black PPO reinforced recycled pellets are listed as low as about 7,700 yuan/ton on 1688 (industrial grade, low quality). Production capacity and recycled trade distribution are concentrated in East China (Ningbo/Suzhou/Dongguan for trade distribution) and South China (Dongguan/Shenzhen agent clusters); the main hubs for recycled trade distribution are Yuyao/Cixi in Zhejiang and Zhangmutou in Guangdong.
6.2 Quotation Details on 2026-09-11 (6 valid items, total purchasable quantity 190 tons)
The following are 6 valid PPO material details from the primary quotation dated 2026-09-11. Note: In the quotation, the item listed as “PSU recycled material | PPO: beige 25,000” has a specification inconsistency and is suspected to be a PSU typo, so it is not included in the PPO sample and has been excluded. For black high-temperature material, there are two price levels, 15,500 and 23,500 yuan/ton, with a large price difference, possibly due to quality or batch differences, which need to be verified.
Table 11 Recycled PPO Quotation Details (2026-09-11, 6 valid entries, PSU conflicting items excluded)

6.3 PPO/PPE Naming Correspondence
Terms like PPO, PPE, MPPO, PPE(REC), and rPPO are often used interchangeably in the market. Before selecting or quoting, you must first cross-check them. See Table 12 for details.
Table 12 PPO/PPE Naming Comparison Table
| name/call | Full name | Remarks |
|---|
| PPO | Polyphenylene Oxide | U.S./DuPont - Noryl series common name |
| PPE | Polyphenylene Ether | Japan / National standard academic title, =PPO |
| MPPO/MPPE | Modified polyphenylene ether | Mainstream in the market, mainly PPO/PS alloy |
| PPE(REC) | Recycled polyphenylene ether | GB/T 40006.13-2025 Naming |
| rPPO/rPPE | Recycled PPO | Industry slang |
6.4 Policies and Regulations
China: GB/T 40006.13-2025 (Special Standard for Recycled PPE, effective 2026-02-01) and GB/T 40006.1-2021 General Rules. Domestic vehicle manufacturers (BYD, NIO, XPeng, etc.) have ESG procurement guidance for recycled content in their supply chains, but there is currently no national-level regulation mandating a percentage of recycled materials (to be verified). Imports of recycled plastic pellets require the "Environmental Project Test Report for Recycled Plastic Pellets", a declaration of legal source of raw materials, MSDS, and quality certificates (MFR/ash content).
European Union (Strong Driver): The new ELV Regulation (EU) 2026/1738 has been implemented — from September 2026, the proportion of post-consumer recycled plastics in new vehicles must be ≥15%, and from September 2032, ≥25%, with at least 20% of that required to come from closed-loop recycling of end-of-life vehicles, only recognizing post-consumer waste. WEEE and RoHS 2011/65/EU require recycled PPO to control polybrominated biphenyls (PBB/PBDE), phthalates, etc.
USA/Japan: The United States has no federal law mandating the proportion of recycled materials, relying on UL2809 recycled content declarations and brand procurement requirements; Japan promotes it through the Home Appliance Recycling Law, and PPO recycling is mostly conducted within corporate closed loops (specific legal provisions need to be verified).
6.5 Emission Reduction Data
No authoritative public figures were found for PPO-specific 'recycled vs. virgin' precise carbon emission reduction percentages, noted as pending verification. Industry-level facts that can be referenced (not PPO-specific, source must be indicated): SABIC launched a PCR-based Noryl product portfolio, with formulations containing more than 25% PCR, of which NH5120RC3 contains 30% PCR; simultaneously, SABIC launched fully ISCC PLUS certified bio-based versions (300 grades). Industry benchmark LCA (SABIC-certified circular polymers, polyolefin scope): advanced recycling routes save about 2 kg CO₂/kg — cannot be directly applied to PPO, only for order-of-magnitude reference. Qualitative conclusion: PPO virgin synthesis processes are complex and energy-intensive; mechanical recycling skips the monomer synthesis step, making emission reduction and energy saving feasible, but specific percentage points/ton energy consumption data await a PPO-specific LCA report.
6.6 Southeast Asia Import Channels and Material Source Background
Policy and Trade Background: After China's 'Waste Ban,' sources of waste plastics have shifted to Southeast Asia. Chinese-funded companies, after establishing factories in Vietnam, Thailand, and Malaysia, export recycled pellets back to China. Regarding tariffs, under the ASEAN Free Trade Agreement/RCEP, over 90% of products enjoy zero tariffs (a certificate of origin is required), with an additional value-added tax applicable; goods originating from RCEP member countries can enjoy preferential rates under the agreement.
Characteristics of each country (qualitative): Vietnam's waste plastic pelletizing capacity in 2024 is about 680,000 tons (nearly three times that of 2020), about 65% operated by Chinese capital/Chinese-controlled enterprises, mainly supplying recycled content demand for brands in Japan, South Korea, Europe, and the United States, and imported Chinese plastic pellets enjoy zero tariffs; Thailand issued the "National Plastic Waste Management Roadmap (2022-2027)", with a relatively complete policy system; Malaysia used to accept a large amount of waste plastic transferred to China, and after environmental supervision became stricter, it became standardized; Indonesia/Philippines serve as supplementary source countries.
Regarding the meaning of recycled PPO (qualitative): As recycled PPO is a niche specialty material, specific trade data for Southeast Asia is not publicly available. The above outlines the general channels for recycled engineering plastics; the Southeast Asian sources of specialty PPO are mainly qualitative, and the specific trade volume of PPO needs verification. Risk points: The quality of recycled pellets in Southeast Asia is uneven and they are prone to being withheld; imports need to be labeled 'Recycled Plastic Granules' and indicate the source, along with an attached environmental inspection report.
