同样一吨TPE，报价从八千到三万差出三倍。只比单价，最后都在返工单上连本带利还回去。
先给结论：TPE 价格区间一句话
TPE 多少钱一吨？先给一个参考区间（以近期市场常见价为例，实际以实时行情和具体牌号为准）：
| 体系 | 参考价（元/吨） | 说明 |
|---|
| SBS 基 TPE | 约 8000-12000 | 鞋材、玩具，成本敏感 |
| SEBS 基 TPE | 约 12000-18000 | 护套、密封、日用品主力 |
| TPV | 约 15000-25000 | 汽车密封条，耐老化 |
| TPU | 约 20000-35000 | 线缆、脚轮、高耐磨 |
| TPEE | 约 30000-50000+ | 波纹管、弹簧，耐高温 |
同一“TPE”三个字，价格能差 5 倍——因为 TPE 是个家族，SBS 基和 TPEE 根本不是一类生意。问“TPE 多少钱一吨”之前，先问自己一句：要哪个体系？体系不定，价格没有意义。
技术金句：TPE 的价格是体系价，不是材料价——先定体系再谈钱，不然比价就是比了个寂寞。
价格为什么年年变？因为 TPE 是化工周期品。 石化原料的产能周期、地缘供应、下游需求，都写在 TPE 价格里。
今天问的价，只能代表今天的行情——做预算、报价、备货，都要给价格留波动余量。
这也是为什么正规供应商会标注“以实时报价为准”——不是推脱，是行业诚实。
为什么价格跟着 SEBS 走？成本构成拆给你看
TPE 的价格锚点，是上游基料。一条链看清楚：
苯乙烯、丁二烯 → SBS → SEBS（加氢）→ TPE 改性料
SEBS 是主流 TPE 的核心基料，它一涨，整个 TPE 家族跟着动。看 TPE 行情，先看 SEBS 行情，再往上看苯乙烯和丁二烯——这两个单体是石化周期的晴雨表。
一吨 SEBS 基 TPE 的成本大致构成：
| 成本项 | 占比（约） | 说明 |
|---|
| 基料（SEBS/SBS） | 50%-65% | 价格主驱动 |
| 白油 | 10%-20% | 等级差几倍 |
| 助剂/色母 | 5%-10% | 阻燃、抗氧、色粉 |
| 加工与检测 | 10%-15% | 双螺杆改性、品控 |
| 毛利 | 10% 左右 | 随行就市 |
基料一吨涨 1000，TPE 每吨至少跟涨 500-800。所以真正的行情判断，要盯上游单体价格，而不是盯成品报价——成品报价是果，上游原料是因。
六个变量：同样的 TPE，价格差在哪
同一体系内，六个变量决定报价高低：
变量一 · 基料牌号：SEBS 不同牌号，分子量、加氢度不同，价差能到 30%。料贵不贵，先看基料牌号。
变量二 · 白油等级：食品级白油 vs 工业白油，价差数倍。食品级 TPE 的贵，一半贵在白油上。
变量三 · 助剂体系：阻燃剂、抗紫外线剂、抗氧剂，功能越多越贵。同样硬度，阻燃级比普通级贵 15%-30%。
变量四 · 填料比例：填料多的“经济型”，价格低但物性差——拉伸强度、回弹、耐温全面缩水。便宜 2000，可能换回一半性能。
变量五 · 认证等级：FDA / EU 认证、医疗级，价格再上 20%-50%。认证不是装饰，是真金白银的合规成本。
变量六 · 品牌与稳定性：大牌正牌 vs 小厂副牌，价差 10%-30%，换来的是批次稳定性和数据可追溯。买的是料，也是确定性。
六个变量里，最容易出猫腻的是白油和填料——表面看不出，一测物性全现形。六个变量，就是六道考题——供应商答得越细，报价越可信。
行情怎么跟？三个信号就够了
TPE 价格波动，不用天天盯盘，盯三个信号就够：
信号一 · 苯乙烯和丁二烯价格。
这两个是 SBS/SEBS 的原料，它们的周度行情，就是 TPE 成本的先行指标——上游涨，成品跟涨是时间问题，提前一个月备货就是赚。
信号二 · SEBS 大厂出厂价。SEBS 产能集中，大厂调价基本定调全市场。看 SEBS 出厂价，比看任何 TPE 报价都早一步。
信号三 · 下游开工率。终端需求一旺，改性厂库存见底，报价自然坚挺；需求一冷，报价松动的就是议价空间。开工率是需求的温度计。
| 信号 | 看什么 | 预判什么 |
|---|
| 单体价格 | 苯乙烯/丁二烯周价 | 成本趋势 |
| SEBS 出厂价 | 大厂调价公告 | 全市场风向 |
| 下游开工率 | 改性厂订单节奏 | 议价空间 |
三个信号组合用，行情基本不迷路。 做采购的，手机里存三个行情来源，比存十个供应商报价有用——报价是果，信号是因，看因不看果。
**国产与进口的价格差，是另一条行情线。
** 进口 SEBS 基 TPE 和高端 TPV，价格通常比国产同规格高 15%-40%；但性能一致性、批次稳定性、数据可追溯性也更高。
“贵 30% 值不值”没有标准答案，看你的件：出口件、认证件、精密件，进口的确定性值这个差价；内销常规件，国产完全够用。
比价时把“进口/国产”写进需求里，供应商报价才在同一坐标系。
对比表：按用途对号入座
价格要和用途对齐，才有意义。一张表对号入座：
| 用途 | 推荐体系 | 参考价（元/吨） | 预算逻辑 |
|---|
| 鞋底、玩具 | SBS 基 | 0.8-1.2 万 | 成本优先 |
| 护套、握把、密封条 | SEBS 基 | 1.2-1.8 万 | 性价比主力 |
| 汽车密封条、线束 | TPV | 1.5-2.5 万 | 耐老化优先 |
| 线缆护套、脚轮 | TPU | 2-3.5 万 | 耐磨优先 |
| 波纹管、耐热弹簧 | TPEE | 3-5 万+ | 耐温回弹优先 |
预算有限，优先考虑 SEBS 基——它是综合性能和成本平衡得最到位的主力；**预算充足且工况明确，再往 TPV、TPEE 走。
** 反过来，用 SEBS 基就能干的活非要上 TPEE，就是为用不上的性能买单。
**验收补一条：把“价格”和“批次”绑在一起。
供应商今天报的价，明天原料一涨就作废——谈价时锁一个“价格有效期”**（比如 15 天），同时约定“原料大幅波动时重新议价”条款，
两边都不吃亏。
价格是活的，合同要给它留个呼吸口。
科隆客户案例：硬度漂移，换体系换牌号一步到位
杭州一家改性料应用厂，连续几批 TPE 件手感忽软忽硬，客户投诉一批接一批，生产线都不敢放量。客户自己换了两家料，问题照旧。
科隆排查发现是体系与工况错配——原体系的硬度窗口窄，批次波动压不住。配合换体系换牌号（如 SEBS 基换 TPV 基），把硬度批次漂移压住，-40℃ 低温弯折一次通过。价格是选型的结果，不是起点——工况没对准，再便宜的料都是浪费。
常见坑：低价背后的账
“同款 TPE，便宜 2000”——先别高兴，看这四笔账：
| 低价话术 | 背后的账 |
|---|
| “经济型，性价比高” | 填料加多了，物性缩水一半 |
| “食品级，价格一样” | 白油换工业级，认证文件没有 |
| “副牌料，便宜好用” | 指标偏了，批次波动大 |
| “全部都能用” | 没问工况的报价，都是猜 |
低价省下的钱，最后都从返工、退货、索赔里还回去。
TPE 是改性料，不是标品——性能全藏在配方里，价格是配方质量的标尺之一，贵不贵，先看贵在哪。
“副牌料便宜 30%，能用吗？”——这个问题每周都有人问。算一笔账：
假设月用 10 吨，正牌 1.5 万/吨，副牌 1.05 万/吨，每月省 4.5 万，一年省 54 万——听起来很香。但副牌料的代价：
- 1. 批次波动：指标偏了的料，硬度、颜色、流动性可能每批不同，调机时间成倍增加；
2. 隐性损耗：废品率从 2% 升到 8%，10 吨里多废 0.6 吨，每吨损失 1.5 万，每月多亏 9000；
- 3. 客户风险：成品一致性下降，被投诉一次，省下的钱全赔进去还倒贴。
副牌料不是不能用，是有使用边界：低要求、大批量、自己工厂能消化波动的场景，副牌料是合理选择；高要求、小批量、
出口和认证场景，副牌料的“便宜”就是陷阱。
先看工况，再谈便宜——这六个字，是采购省钱的正确姿势。
**价格谈判的一个细节：按“年度量”谈价。
月用 1 吨和月用 10 吨，不是一个价格——把年用量告诉供应商，拿到的是阶梯价；藏着掖着，拿到的是零售价。
** 用量是谈判里最硬的筹码，别浪费。
**再补一个行情提醒：别信“永远最低”的报价。
化工品行情有周期，谁都不能承诺永远低价——低于市场价 15% 以上的报价，先问三个问题：什么体系？什么等级？批次怎么保障？
** 三问问完，低价是馅饼还是陷阱，基本清楚。
采购验收：怎么询价不踩坑
询 TPE 价格，四句话问法，问完就知道供应商专不专业：
1. 报工况，不报牌号：“我的件是密封条，连续温度 90℃，硬度 70A，月用 10 吨”——专业供应商会按工况推体系，而不是直接报价；
- 2. 要体系，不要模糊价：“SEBS 基还是 TPV？”——体系不说清，报价没法比；
- 3. 要留样，不要口头承诺：每批留样 500g，物性测试条件写进合同——批次可追溯，争议才有依据；
- 4. 要数据，不要报告截图：同批次留样 + 完整物性数据，比什么承诺都有用。
四句话问完，谁专业谁不专业，一清二楚。四句话问法加询价清单，双管齐下，你就是最不好糊弄的采购。**** 价格可以谈，工况和数据不能省。
再给一个判断方法：把“每吨价格”换算成“每件成本”。一吨 TPE 做多少件，每件摊多少料钱，才是真正的成本。
同一吨料，良率高 2 个点，摊到每件的成本可能比便宜 1000 块/吨的料还低——采购算成本，要算到件，不能只算到吨。
这是很多老采购的压箱底经验。
关于“价格构成表”这个领取物，多说一句： 表里会把基料、白油、助剂、加工、毛利五项摊开，
看表时重点看白油和助剂两行——这两项是最容易被偷换成本的，也是报价差异的大头。
拿到表，对着自己的工况看，价格贵在哪、便宜在哪，一目了然。
**最后补一句给老板的换算：TPE 涨 1000 块/吨，摊到你的产品上，每件成本涨多少？
算清这一笔，就知道该备货还是该观望——行情判断不是玄学，是把上游信号翻译成自己的成本。**
采购补一条：把价格谈判和工况确认绑定——供应商问得越细（硬度、温度、介质、用量），报出来的价越靠谱；什么都不问就报价的，
要么是专家，要么是外行。
多数情况下是后者。
最后给一张询价信息清单，照着填就不会漏：
| 必填项 | 你的答案 |
|---|
| 件的用途与形态 | 密封条 / 护套 / 脚轮… |
| 目标硬度 | Shore A ___±3 |
| 连续使用温度 | ___℃ |
| 接触介质 | 空气 / 油 / 酸碱 |
| 认证要求 | 无 / 食品级 / 医疗级 / 阻燃 |
| 月用量 | ___ 吨 |
| 进口或国产 | 不限 / 国产优先 / 进口优先 |
七个格子填满，发出的询价单，供应商回过来的就是“方案”而不是“猜”——同样的询价，信息全的和信息少的，报价能差出 15% 的议价空间。
再补一个防坑细节：报价单上的“含税不含税”。 同样 1.5 万/吨，含 13% 增值税和不含税是两个数字，折算下来每吨差近 2000 块。
询价时把“含税、含运费、账期”三件事问清楚——三件事不锁死，比价就是比错对象。
**还有一个容易被忽略的：小批量和大批量的价差结构。
** 改性料常按量分档：1 吨以下、1-5 吨、5 吨以上、月采购协议价，档位之间价差能到 10%-20%。
问价时直接报你的月用量，让供应商按对应档位报价，而不是拿零售价当基准谈。
**最后补一个趋势判断：改性料的价格，越来越看“服务含量”。
同样的 SEBS 基 TPE，有的厂只卖料，有的厂带选型建议、带打样调试、带批次追溯——服务含量不同，价差 10% 是常态。
** 询价时把“要不要技术支持”写进需求，比价才公平：买的是“料+服务”，还是光买料，先想清楚。
价格问题最后落一句：TPE 的价，问体系、问等级、问工况、问批次，四问问完，谁也蒙不了你。**价格这一课讲完，下次询价，你就是行家。
把吨价换算成件成本，才算到点子上了；行情不迷路，预算不超支。把这套问法记熟，价格的主动权就在你手里。**
小结
如果你也在做TPE，建议先把工况表列全，再来对材料，也欢迎转给需要的同事。
价格跟着 SEBS 走、六个变量定高低、体系价不是材料价、低价四笔账记牢——TPE 询价这件事，主动权就回到你手里了。
For the same ton of TPE, the price ranges from 8,000 to 30,000, a difference of three times. If you only compare the unit price, in the end, it all comes back to the rework order with both principal and interest.
Conclusion first: TPE price range in one sentence
How much is TPE per ton? First, here is a reference range (based on recent common market prices; the actual price depends on real-time market conditions and specific grades):
| system | Reference price (CNY/ton) | Explanation |
|---|
| SBS Based TPE | Approximately 8,000-12,000 | Shoe materials, toys, cost-sensitive |
| SEBS-based TPE | About 12,000-18,000 | Cables, seals, and daily necessities are the main products |
| TPV | Approximately 15,000-25,000 | Car sealing strip, aging resistant |
| TPU | About 20,000-35,000 | Cables, casters, high wear resistance |
| TPEE | About 30,000-50,000 | Bellows, springs, high-temperature resistant |
The same three letters 'TPE' can have a price difference of 5 times—because TPE is a family, and SBS-based and TPEE are not the same type of business. Before asking 'how much is TPE per ton,' first ask yourself: which system do you want? Without a defined system, the price is meaningless.
Tech Quote: The price of TPE is the system price, not the material price—set the system first before talking money, otherwise comparing prices is just comparing emptiness.
Why does the price change every year? Because TPE is a chemical cyclical product. The production capacity cycle of petrochemical raw materials, geopolitical supply, and downstream demand are all reflected in the TPE price.
The price asked today can only represent today's market situation—when making budgets, quotations, or stocking inventory, you have to leave room for price fluctuations.
This is also why reputable suppliers label 'subject to real-time quotes'—it's not an excuse, but industry honesty.
Why does the price follow SEBS? Let me break down the cost structure for you
The price anchor for TPE is the upstream raw material. Let's clearly look at one chain:
Styrene, Butadiene → SBS → SEBS (Hydrogenated) → TPE Modified Material
SEBS is the core base material of mainstream TPE. When it rises, the entire TPE family follows. To look at the TPE market, first look at the SEBS market, then look further at styrene and butadiene—these two monomers are the barometers of the petrochemical cycle.
The approximate cost composition of one ton of SEBS-based TPE:
| Cost item | Proportion (approx.) | Explanation |
|---|
| Base Material (SEBS/SBS) | 50%-65% | Price-driven |
| White oil | 10%-20% | Level difference of several times |
| Additive / Color Masterbatch | 5%-10% | Flame retardant, anti-oxidation, color powder |
| Processing and Inspection | 10%-15% | Twin-screw modification, quality control |
| Maori | about 10% | Follow the market |
The base material has risen by 1,000 per ton, and TPE will rise by at least 500-800 per ton. So the real market judgment should focus on the price of upstream monomers, not the finished product quotes—the finished product quotes are the result, and the upstream raw materials are the cause.
Six variables: the same TPE, where is the price difference
Within the same system, six variables determine the price.
Variable One · Base Material Grade: SEBS Different grades have different molecular weights and hydrogenation degrees, and the price difference can reach 30%. To determine if the material is expensive, first look at the base material grade.
Variable Two · White Oil Grade: Food-grade white oil vs. industrial white oil, price difference is several times. Food-grade TPE is expensive, half of the cost is due to the white oil.
Variable Three · Additive System: flame retardants, UV stabilizers, antioxidants. The more functions, the more expensive. At the same hardness, flame-retardant grade is 15%-30% more expensive than the standard grade.
Variable Four · Filler Ratio: The "economy" version with more filler has a lower price but poorer properties — tensile strength, resilience, and temperature resistance all decrease. Cheaper by 2000, but it may cost you half the performance.
Variable Five · Certification Level: FDA / EU certified, medical grade, price increases by another 20%-50%. Certification is not decoration; it is a real, substantial compliance cost.
Variable Six · Brand and Stability: Big-name genuine brands vs. small factory sub-brands, with a price difference of 10%-30%, trading for batch stability and data traceability. What you are buying is not only the material but also certainty.
Among the six variables, the ones most likely to have tricks are white oil and fillers—on the surface, you can't see it, but once you test the physical properties, everything becomes apparent. The six variables are like six exam questions—the more detailed the supplier's answers, the more reliable the quotation.
How to follow the market? Three signals are enough.
TPE price fluctuates, no need to watch the market every day, just watch three signals:
Signal One · Prices of Styrene and Butadiene.
These two are raw materials for SBS/SEBS. Their weekly market trends are the leading indicators of TPE costs—when upstream prices rise, the price of finished products will follow sooner or later. Stocking up a month in advance is a profit.
Signal Two · Factory price of SEBS from major manufacturers. SEBS production capacity is concentrated, and price adjustments by major manufacturers basically set the tone for the entire market. Watching SEBS factory prices is a step ahead of watching any TPE quotes.
Signal Three · Downstream Operating Rate. When end-user demand is strong, modified material manufacturers' inventories hit the bottom, and prices naturally remain firm; when demand cools, the flexibility in pricing is the bargaining space. The operating rate is a thermometer of demand.
| Signal | What are you looking at? | Predict what |
|---|
| Unit price | Styrene/Butadiene Periphery | Cost Trend |
| SEBS Factory Price | Major Factory Price Adjustment Announcement | Overall Market Trend |
| Downstream operating rate | Modified factory order rhythm | Bargaining room |
Using a combination of three signals, you basically won’t get lost in the market. For procurement, having three market sources saved on your phone is more useful than saving quotes from ten suppliers—the quotes are the result, the signals are the cause; look at the cause, not the result.
The price difference between domestic and imported products is another market trend line.
** Imported SEBS-based TPE and high-end TPV are usually 15%-40% more expensive than domestically produced ones of the same specification; however, their performance consistency, batch stability, and data traceability are also higher.
There is no standard answer to 'Is it worth 30% more'; it depends on your parts: for export parts, certified parts, or precision parts, you can determine the value of this price difference against imports; for regular domestic sales parts, domestic products are completely sufficient.
When comparing prices, include 'imported/domestic' in the requirements so that suppliers' quotes are on the same baseline.
Comparison Table: Match to Purpose
The price must align with the purpose to be meaningful. A table for matching items accordingly:
| Purpose | Recommendation system | Reference price (CNY/ton) | Budget logic |
|---|
| Soles, toys | SBS base | 8,000-12,000 | Cost priority |
| Sheath, handle, sealing strip | SEBS base | 12,000–18,000 | Cost-effective main force |
| Car sealing strips, wiring harness | TPV | 15,000-25,000 | Aging resistance takes priority |
| Cable sheath, caster | TPU | 20,000-35,000 | Wear resistance priority |
| Bellows, heat-resistant springs | TPEE | 30,000 to 50,000 | Temperature-resistant and resilient priority |
With a limited budget, prioritize SEBS-based materials — they are the mainstay with the best balance of overall performance and cost; **if the budget is sufficient and the working conditions are clear, then move towards TPV or TPEE.
** On the contrary, insisting on using TPEE for tasks that can be done with SEBS is just paying for performance you can't use.
**Acceptance Supplement: Bind 'price' and 'batch' together.
The price quoted by the supplier today will become invalid as soon as the raw material price rises tomorrow—when negotiating, lock in a 'price validity period' **(for example, 15 days), and also agree on a clause to 'renegotiate in case of significant raw material fluctuations'.
Neither side suffers a loss.
Prices are flexible, and contracts should leave them some breathing room.
Cologne Customer Case: Hardness Drift, Switching Systems and Grades in One Step
A modified material application factory in Hangzhou has been experiencing inconsistent hardness in several consecutive batches of TPE parts, with the feel alternating between soft and hard. Customers have been complaining batch after batch, and the production line dares not ramp up production. The customer has even switched to two different materials themselves, but the problem remains the same.
Cologne inspection found that it was a mismatch between the system and the working conditions—the original system had a narrow hardness window, and batch fluctuations could not be controlled. By switching systems and grades (e.g., from SEBS-based to TPV-based), the batch hardness drift was controlled, and it passed the -40℃ low-temperature bending test on the first try. Price is a result of the selection, not the starting point—if the working conditions are not aligned, no matter how cheap the material is, it is a waste.
Common Pitfall: The Accounts Behind Low Prices
"Same TPE, 2000 cheaper" — don't get excited yet, look at these four accounts:
| Low-price pitch | The account behind |
|---|
| "Economical, cost-effective" | Too much filler was added, and the physical properties shrank by half. |
| "Food grade, same price" | Replace the white oil with industrial grade, no certification documents |
| "Second-brand material, cheap and practical" | The indicators are off, and the batch fluctuations are large. |
| ‘All can be used’ | The quote didn't ask about the working conditions, it was all a guess. |
The money saved from low prices eventually gets paid back through rework, returns, and claims.
TPE is a modified material, not a standard product — its performance is entirely embedded in the formula, and the price is one of the measures of the formula's quality. Whether it's expensive or not, first see what makes it expensive.
"The secondary brand material is 30% cheaper, can it be used?" — This question is asked every week. Let's do the math:
Assuming a monthly usage of 10 tons, with the main brand at 15,000 per ton and the secondary brand at 10,500 per ton, saving 45,000 per month, 540,000 per year—it sounds great. But the cost of using the secondary brand material is:
- 1. Batch fluctuations: For materials with off-spec indicators, hardness, color, and fluidity may vary from batch to batch, causing machine adjustment time to increase exponentially;
2. Hidden losses: The defect rate increased from 2% to 8%. In 10 tons, an extra 0.6 tons is wasted, with a loss of 15,000 per ton, resulting in an additional monthly loss of 9,000.
- 3. Customer risk: Finished product consistency decreases, get complained about once, and all the money saved will be lost, even resulting in a loss.
Secondary-grade materials are not unusable; they have usage boundaries: for scenarios with low requirements, large quantities, and where one's own factory can handle fluctuations, secondary-grade materials are a reasonable choice; for high requirements, small quantities,
In export and certification scenarios, the 'cheapness' of secondary brand materials is a trap.
First look at the working conditions, then talk about cheapness—these six words are the correct approach for procurement to save money.
A detail of price negotiation: negotiate based on 'annual quantity'.
Using 1 ton per month and 10 tons per month are not the same price — tell the supplier your annual usage, and you'll get a tiered price; if you hide it, you'll get the retail price.
** Dosage is the strongest bargaining chip in negotiations, don't waste it.
**Here's another market reminder: Don't believe quotes that claim to be the 'lowest ever'.
The chemical products market is cyclical, and no one can promise permanently low prices—if you see a quote more than 15% below the market price, first ask three questions: What system? What grade? How is the batch guaranteed?
** After asking three questions, it’s basically clear whether the low price is a bargain or a trap.
Procurement Acceptance: How to Ask for Quotes Without Pitfalls
Inquire about TPE prices with four questions, and you will know whether the supplier is professional after asking them:
1. Report the working conditions, not the grade: 'My part is a sealing strip, continuous temperature 90℃, hardness 70A, monthly usage 10 tons' — professional suppliers will recommend the system based on the working conditions, rather than providing a direct quote;
- 2. Focus on the system, not vague prices: 'SEBS-based or TPV?'—if the system is unclear, the quote cannot be compared;
- 3. Keep samples, do not rely on verbal promises: Keep 500g of sample from each batch, and write the physical test conditions into the contract—the batch can be traced, so there is a basis in case of disputes;
- 4. Ask for data, not report screenshots: Retain samples from the same batch. Complete physical property data is more useful than any promises.
After asking four questions, it’s clear who is professional and who isn’t. Asking four questions along with a quotation checklist, using both methods, makes you the hardest procurement person to fool. Prices can be negotiated, but working conditions and data cannot be omitted.
Another method to judge: convert the 'price per ton' into 'cost per piece.' How many pieces are made from one ton of TPE, and how much material cost is allocated to each piece, is the real cost.
For the same ton of material, if the yield rate is 2% higher, the cost per piece might be lower than material that is 1,000 yuan/ton cheaper—when calculating procurement costs, it should be calculated per piece, not just per ton.
This is the hidden trick that many experienced buyers keep to themselves.
A little more about the 'Price Composition Table': the table breaks down five items: base material, white oil, additives, processing, and gross profit.
When looking at the table, focus on the two rows of white oil and additives — these two items are the easiest to have their costs swapped, and they are also the main reason for price differences.
After getting the table, look at your own operating conditions; it's clear at a glance where the price is expensive and where it is cheap.
**One last thing to add to the boss's conversion: TPE increases by 1000 yuan/ton, and when spread over to your product, how much does the cost per unit increase?
Once you calculate this amount, you'll know whether to stock up or wait and see—market judgment isn't mystique, it's about translating upstream signals into your own cost. **
Procurement adds one thing: Tie price negotiations to working condition confirmation—the more detailed the supplier asks (hardness, temperature, medium, quantity), the more reliable the quoted price is; If you quote without asking anything,
is either an expert or an outsider.
Most of the time, it's the latter.
Finally, here's a list of inquiry information. If you fill it out, nothing will be missed:
| Required Items | Your Answer |
|---|
| Uses and Forms of Pieces | Sealing Strips / Sheaths / Casters... |
| Target hardness | Shore A ___±3 |
| Continuous operating temperature | ___°C |
| Contact medium | Air / Oil / Acid/alkali |
| Certification requirement | None / Food grade / Medical grade / Flame retardant |
| Monthly usage | ___ tons |
| Imported or domestic | No limit / Domestic priority / Import priority |
Seven slots are filled. When the inquiry form is issued, the supplier returns a "proposal" rather than a "guess"—for the same inquiry, whether the information is complete or not, the quotation can differ by 15% in negotiation.
Here's another pitfall tip: the quotation sheet says "tax included, excluding tax." Similarly, at 15,000 RMB/ton, including 13% VAT and excluding tax, these are two different numbers, so the difference per ton is nearly 2,000 yuan.
clarified the three things "including tax, including shipping, and payment period" when inquiring—if these three are not locked, the price comparison is the wrong target.
** Another easily overlooked point: the price gap between small and large batches.
** Modified materials are often classified by volume: below 1 ton, 1-5 tons, over 5 tons, monthly purchase agreement price, with price differences between tiers reaching 10%-20%.
When asking for a price, directly state your monthly usage, and have suppliers quote according to the price level, rather than using retail prices as a benchmark.
**Finally, a trend assessment: the price of modified materials increasingly depends on "service content."
For the same SEBS-based TPE, some factories only sell materials, some provide selection advice, sample debugging, and batch traceability—depending on service content, a 10% price difference is normal.
** When inquiring, include "whether you need technical support" in your requirements for fair pricing: are you buying "materials + services" or just materials? Think carefully.
Finally, about pricing: TPE prices—ask about the system, grade, operating conditions, and batches—after all four questions, no one will be fooled. **After this lesson on price, next time you ask for a price, you'll be the expert.
Convert the tonnage price into unit cost, and you'll hit the mark; Don't get lost in the market, don't overrun your budget. Once you master this questioning method, the initiative in pricing is in your hands. **
Summary
If you're also working on TPE, I suggest listing the operating conditions list first, then checking the materials. Feel free to share with colleagues who need it.
Price follows SEBS, six variables set the high-low price, system price is not material price, low price is remembered in four key accounts—TPE inquiry now has the initiative back in your hands
