生物基TPE吹得热闹，含量多少没人给准话。别信口头，含量要白纸黑字。
含量没人给准话，别信口头
生物基 TPE 是“证据活”：含量、认证、价格。结论先给：生物基比例要认证书不认嘴——证据，是生物基的通行证。
生物基TPE最大的坑：销售嘴上说40%生物基，证书拿不出来——证据，是生物基的护身符。
生物基是趋势关：含量有据，采购才稳。含量没据，宣传白搭——生物基，是采购的趋势题。
含量是硬指标，为什么看证据
生物基含量定等级：含量达标才算。含量，是生物基的尺。
认证要可查：证书编号能查。认证，是生物基的凭证。
价格要合理：生物基贵在原料。价格，是生物基的成本。
含量、认证、价格，怎么核
含量：白纸黑字写清。含量，是头一判据。
认证：证书核验编号。认证，是第二判据。
价格：按含量比价。价格，是第三判据。
生物基采购，一张表对照清楚
| 项目 | 口头 | 白纸黑字 | 判断 |
|---|
| 含量 | 不可信 | 有据 | 要书面 |
| 认证 | 可造假 | 可查 | 核编号 |
| 价格 | 虚高 | 合理 | 按据 |
| 批次 | 不稳 | 可溯 | 锁批次 |
表格读法：证据在手，采购不慌，ASTM D6866报告按批次附。
证据，是生物基的通行证。
含量达标有据，采购核这四项
| 项目 | 要求 | 判断 |
|---|
| 含量 | 书面 | 达标 |
| 认证 | 可查 | 达标 |
| 价格 | 合理 | 达标 |
| 批次 | 可溯 | 达标 |
表格读法：采购一项项核，证据看得见，证书编号和含量值对得上。
证据，是生物基的护身符。
信口头不核认证，花了溢价买概念
坑一：信口头。口头报含量，交货时证书含量差一半——书面必要。
坑二：认证不核。假证——认证必查。
坑三：价格乱比。买贵——按含量比。
含量、认证、追溯——采购前看证据
三问：什么含量、什么认证、什么价格。一验：证书核验实测——三问一验，供应商底细清楚。
证据验证要先行：先要生物基含量证书和ASTM D6866编号，再谈采购——证据，是生物基的通行证。
留样要成习惯：每批留样，物性按批次复测。批次换料先对比再放量——批次稳，客诉少。

生物基 TPE 别信口头，要纸面上的含量。问“多少比例生物基”，答“很高”的，直接放下。
要 ASTM D6866 报告，编号官网可查。含量比例、检测日期、发证机构三项对上，才算数。
生物基含量按碳来源算，不是按重量。同样标“生物基”，10% 和 50% 是两个价、两本账。
拿“可堆肥”当“生物基”卖，是常见套路。能降解不等于生物基含量高，两个认证别混。
含量白纸黑字写进合同，客户验厂也拿得出报告。绿色卖点才站得住，不被倒查打脸。

科隆客户案例：收缩率不稳波动大，小批试产续三单
金华一家改性料应用厂，生物基 TPE 件收缩率不稳，尺寸波动大。科隆配合小批试产验证后再放量，尺寸稳定，客户连续三个批次续单。小批试产，把尺寸锁死在放量前——尺寸问题，先看体系稳定性。

Bio-based TPE is being hyped up, but no one gives a definite number for the content. Don’t trust verbal claims; the content should be in writing.
No one can give an exact content amount, don't trust verbal claims.
Bio-based TPE is 'evidence alive': content, certification, price. Conclusion first: the bio-based ratio requires a certificate, not just verbal claims — evidence is the passport for being bio-based.
The biggest pitfall of bio-based TPE: salespeople claim 40% bio-based, but cannot produce the certificate — evidence is the amulet of bio-based.
Bio-based is a trend issue: if the content is verified, procurement is stable. If the content is unverified, promotion is meaningless—bio-based is a procurement trend topic.
Content is a hard metric, why look at evidence?
Classification of bio-based content: Only content that meets the standard counts. Content is the measure of bio-based material.
Certification must be verifiable: the certificate number can be checked. Certification is proof of being bio-based.
The price should be reasonable: the expense of bio-based products lies in the raw materials. The price reflects the cost of bio-based products.
Content, certification, price, how to verify
Content: Clearly written in black and white. Content is the primary criterion.
Certification: Certificate verification number. Certification is the second criterion.
Price: Compare by content ratio. Price is the third criterion.
Bio-based procurement, everything clearly matched on one sheet
| Project | Verbal | black and white on paper | Judgment |
|---|
| content | Unreliable | Well-founded | In writing |
| Certification | Can be faked | Verifiable | Core Number |
| Price | Overestimated | reasonable | according to |
| Batch | Unstable | traceable | Lock batch |
How to read the table: With evidence in hand, procurement is not anxious; ASTM D6866 reports are attached by batch.
Evidence is the passport for biobased materials.
Content meets standards with evidence, these four items should be checked during procurement
| Project | Requirement | Judgment |
|---|
| content | Written | Meet the standard |
| Certification | Verifiable | Meet the standard |
| Price | reasonable | Meet the standard |
| Batch | traceable | Meet the standard |
Table reading method: Check each purchase item one by one, the evidence is visible, and the certificate number matches the content value.
Evidence is the talisman of biology.
Trusted without verification, paid a premium for the concept
Pitfall 1: Relying on verbal agreements. The verbally reported content is half of the certificate content upon delivery — written documentation is necessary.
Pitfall 2: Certification is not verified. Fake certificates—certification must be checked.
Pitfall three: Comparing prices chaotically. Paying more—compare based on content.
Content, Certification, Traceability — Check the Evidence Before Purchasing
Three questions: what content, what certification, what price. One verification: certificate verification and actual measurement — three questions and one verification, the supplier's details are clear.
Evidence verification must come first: you need a bio-based content certificate and an ASTM D6866 number before discussing procurement—evidence is the pass for bio-based materials.
Making sample retention a habit: retain samples for each batch, and re-test the physical properties by batch. Before switching materials between batches, compare them first before scaling up—the batch is stable, and customer complaints are few.
False labeling, unlicensed, premium: compared in a table
| Phenomenon | Reason | Countermeasure |
|---|
| scammed | Verbal | In writing |
| Fake certificate | Do not verify | Core number |
| Bought at a high price | Messy price comparison | By content |
| Batch disorder | Do not trace back | Lock batch |
| Customer complaint | Lack of evidence | Follow procedures |
For bio-based TPE, don't rely on verbal claims, get the content on paper. If you ask 'what percentage is bio-based' and the answer is 'very high', put it down immediately.
ASTM D6866 report is required, the report number can be checked on the official website. The three items of content ratio, test date, and issuing organization must match to be valid.
The bio-based content is calculated based on the carbon source, not by weight. Even if both are labeled "bio-based," 10% and 50% represent two different values and two separate accounts.
Selling 'compostable' as 'bio-based' is a common trick. Being degradable does not equal having a high bio-based content; don't confuse the two certifications.
The content is clearly written in black and white in the contract, and the customer can provide the report during the factory inspection. Only green selling points are sustainable and won't be questioned or backfire.
Bio-based TPE requires an ASTM D6866 report, with content calculated based on carbon source rather than weight. If asked about the proportion of bio-based content, just give a high figure directly. It only counts if the content proportion, test date, and issuing organization all match.
Selling compostable products as bio-based is a common tactic. Being degradable does not equal having a high bio-based content; 10% and 50% are two different price points. The content is clearly written in the contract, and customers can present reports during factory inspections.
The bio-based content is calculated based on the carbon source, not by weight. Similarly, labeling something as bio-based, 10% and 50% are two completely different accounts; only then can the green selling point stand without being checked and disproven.
The content is written in black and white in the contract, and the client can produce the report during the factory inspection.
Green selling points are the only ones that can stand without being retroactively checked and disproved. The biobased content is calculated based on the carbon source, not by weight, so labeling both 10% and 50% biobased results in two different prices and two separate accounts.
Don't believe oral claims about the content of bio-based TPE; always check the documented figures.
. When asked about the proportion of bio-based content, many people directly say it is very high. To be valid, you need to provide the ASTM D6866 report number, which can be checked on the official website, and the three items — content proportion, test date, and issuing organization — must match.
Cologne Customer Case: Unstable Shrinkage Rate Fluctuating Greatly, Small Batch Trial Production Continues with Three Orders
A modified material application factory in Jinhua has unstable shrinkage rates and large dimensional fluctuations for bio-based TPE parts. After Cologne cooperated with small batch trial production verification before mass production, the dimensions were stable, and the customer placed follow-up orders for three consecutive batches. In small batch trial production, lock the dimensions before mass production—the dimensional issues should first look at the system stability.
Summary
For the procurement of bio-based TPE, the content should be prioritized first, and certification should be verified afterwards. Do not trust verbal claims about the content; written evidence is the pass.
