一觉醒来供应商断供，产线等着料下锅。断供说来就来，替代货源得提前备。
一觉醒来断供，替代货源没提前备
TPE 断供，预案是护身符：替代、备货、验证。结论先给：替代货源提前备，断供不慌——预案，是断供的底牌。
TPE断供最大的坑：等断供了才找替代，产线已经停在那——预案，是断供的保险。
断供是风险关：有预案，断供不慌。没预案，停产亏钱——断供，是采购的风险题。
断供说来就来，为什么先做预案
上游停产：装置检修、意外停。断供，说来就来。
物流受阻：运输问题。断供，防不胜防。
行情波动：价格暴涨，供应收紧。断供，跟着行情走。
替代、验证、备货，预案怎么搭
替代：备好替代牌号。替代，是断供的备胎。
验证：替代提前验证。验证，是替代的体检。
备货：安全库存留足。备货，是断供的缓冲。
断供应对，一张表对照清楚
| 措施 | 做什么 | 判断 |
|---|
| 替代 | 备牌号 | 必做 |
| 验证 | 提前测 | 必做 |
| 备货 | 留库存 | 必做 |
| 监控 | 盯上游 | 必做 |
表格读法：措施逐项备，断供不慌，第二供应商半年前就跑完样。
预案齐，断供不慌。
断供不停线，预案核这四项
| 项目 | 要求 | 判断 |
|---|
| 替代 | 已备 | 达标 |
| 验证 | 通过 | 达标 |
| 备货 | 充足 | 达标 |
| 监控 | 在盯 | 达标 |
表格读法：预案一项项核，风险看得见，安全库存按周数标。
预案，是断供的底牌。
断供才找替代，产线先停工
坑一：断供才找。原供一断，新牌号没验证就上机，良率当场跳水——预案必做。
坑二：替代不验证。翻车——验证必做。
坑三：库存不足。停产——备货必做。
替代料、验证、安全库存——提前备
三问：什么替代、什么库存、什么周期。一验：替代验证实测——三问一验，供应商底细清楚。
预案验证要先行：先把第二供应商小批验证跑完、安全库存算出来，再谈原供合同——预案，是断供的保险。
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。
断料、停线、急采：对照一张表
| 现象 | 原因 | 对策 |
|---|
| 停产 | 无预案 | 做预案 |
| 翻车 | 替代不验 | 提前验 |
| 断货 | 库存少 | 留库存 |
| 被动 | 不监控 | 盯上游 |
| 客诉 | 断供 | 备替代 |
断供来了才找替代，生产线停一天的钱够买半年备货。 临时找料又贵又不一定合适，停产损失最大。
预案三件套：备替代牌号、提前验证、留安全库存。 三样都备了，断供不慌，缺一样真断供就抓瞎。
替代牌号别临时测，提前小批试产过三关。 真断供时验证来不及，平时就要把替代料跑通，急不得。
断供预案是供应链的“备胎”，监控上游行情是眼睛。 盯SEBS涨价、盯原厂排产，提前预警才来得及切料。
替代牌号验证通过、安全库存够周转一个月，断供时直接切料不停线。 预案每年更新一次，别写一份放三年。
替代牌号提前小批试产，别等断供才测。
替代料要按硬度窗口、剥离力、耐温三项重测，和主料做盲测对比，手感差一档就不能直接切。
安全库存按一个月用量备在干燥仓库，别囤露天受潮。替代牌号的物性表和TDS一起存档，切料时照着核。
替代货源平时跑通，真断供时验证来不及。主供加备供两家小批试产都过，备供占三成产能，断供一周内切过去不耽误生产。
盯SEBS涨价和原厂排产，提前两周预警。氢化装置检修、原油大涨都提前两周有信号，预案每年更新一次，别写一份放三年。
断供时临时找料又贵又不一定合适。停产损失最大，替代料的硬度剥离力压变要先测过，别等线上停了才到处打电话。
真断供时验证来不及平时就要把替代料跑通急不得。盯SEBS涨价盯原厂排产提前预警才来得及切料，预案每年更新一次别写一份放三年。
临时找料又贵又不一定合适停产损失最大
。三样都备了断供不慌缺一样真断供就抓瞎，
真断供时验证来不及平时就要把替代料跑通急不得盯SEBS涨价盯原厂排产提前预警才来得及切料。

Woke up to find the supplier cut off supply, and the production line is waiting for materials to be fed into it. Supply cuts come suddenly, so alternative sources need to be prepared in advance.
Woke up to a supply cut, alternative sources of goods weren't prepared in advance
TPE supply cut, the contingency plan is a talisman: alternatives, stockpiling, verification. Conclusion first: prepare alternative sources in advance, don’t panic during the supply cut — the contingency plan is the trump card for the supply cut.
The biggest pitfall of TPE supply cutoffs: only looking for alternatives after the supply is cut, when the production line has already stopped—the contingency plan is insurance against supply cuts.
Supply cutoff is a risk checkpoint: if there’s a contingency plan, a supply cutoff won’t cause panic. Without a plan, production stops and you lose money—supply cutoff is a risk issue for purchasing.
A supply cutoff can happen suddenly, so why make a contingency plan first?
Upstream shutdown: unit maintenance, unexpected stoppage. Supply cuts happen suddenly.
Logistics obstructed: transportation problems. Supply disruption, prevention is futile.
Market fluctuations: prices soar, supply tightens. Supply cuts, follow the market trends.
Alternatives, verification, stocking, how to set up contingency plans
Alternative: Prepare alternative grades. An alternative is a backup in case of supply interruption.
Verification: an alternative to preliminary verification. Verification is a substitute for a physical examination.
Stocking: Keep a sufficient safety inventory. Stocking is a buffer against supply disruption.
Cut off the supply correctly, and a table clearly shows the comparison.
| measures | What are you doing? | Judgment |
|---|
| Alternative | Spare part number | Must do |
| Verify | Test in advance | Must do |
| Stocking up | Keep inventory | Must do |
| Surveillance | Target the upstream | Must do |
Table reading: Prepare each measure one by one, don't panic about supply cuts, the second supplier completed the samples six months ago.
With a complete plan, you won't panic if supplies are cut off.
Supply cut without stopping the line, the contingency plan checks these four items
| Project | Requirement | Judgment |
|---|
| Alternative | Prepared | Meet the standard |
| Verify | through | Meet the standard |
| Stocking goods | Adequate | Meet the standard |
| Surveillance | Staring | Meet the standard |
Table reading method: Check each item in the plan one by one, see the risks clearly, and mark the safety stock by week.
The contingency plan is the trump card for cutting off supply.
Only look for alternatives after stopping the supply; the production line stops first.
Pitfall 1: Only look for it after the supply stops. When the original supply is cut off and the new grade is used on the machine without verification, the yield plummets immediately—the contingency plan must be prepared.
Pitfall 2: Skipping verification. Crash — verification must be done.
Pitfall three: insufficient inventory. Production halted — stocking up is a must.
Alternative materials, verification, safety stock — prepare in advance
Three questions: what substitutes, what inventory, what cycle. One verification: substitution verification test—three questions and one verification, supplier details are clear.
Contingency plan verification must come first: first complete the small-batch verification with the second supplier and calculate the safety stock, then discuss the original supplier contract—the contingency plan is insurance against supply disruption.
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 stability is maintained, and customer complaints are reduced.
Material shortage, line stoppage, urgent procurement: Compared against a table
| Phenomenon | Reason | Countermeasure |
|---|
| Discontinued | No plan | Make a contingency plan |
| overturn | Substitute without verification | Early inspection |
| Out of stock | Low stock | Keep inventory |
| Passive | Do not monitor | Target the upstream |
| Customer complaint | cut off supply | standby alternative |
Only when the supply is cut off do they look for alternatives. The cost of a day of production downtime is enough to buy six months of inventory. Sourcing materials at the last minute is expensive and may not be suitable, and the loss from production stoppage is the greatest.
Three-piece contingency plan: prepare alternative specifications, validate in advance, and keep a safety stock. If all three are prepared, supply disruptions won't cause panic; missing one can really leave you scrambling when a disruption occurs.
Don't test alternative grades temporarily; conduct small batch trial production in advance through all three stages. When supply is truly cut off, there's no time for verification, so you need to run the alternative materials through properly during normal times; you can't rush it.
A supply cut contingency plan is the 'spare tire' of the supply chain, and monitoring upstream market conditions is the eyes. Keep an eye on SEBS price increases and the production schedule of the original factory; only by giving early warnings can you have time to switch materials.
Alternative grade verification passed, safety stock is enough for one month of turnover, and production can continue without stopping if supply is cut. The plan is updated once a year, don’t write one and keep it for three years.
Conduct small-scale test production of alternative grades in advance; don't wait until supply is cut off to test.
The alternative material must be re-tested according to the hardness window, peel strength, and temperature resistance, and compared with the main material in a blind test; if the feel is one grade lower, it cannot be cut directly.
Keep the safety stock for one month's usage in a dry warehouse; do not store it outdoors where it can get damp. Archive the physical property tables and TDS of alternative grades together, and check them when cutting materials.
The alternative supply runs smoothly under normal circumstances, but there is not enough time to test it when the main supply is truly cut off. Both the main and backup suppliers passed small-batch trial production, with the backup supplier covering 30% of the capacity. Switching to the backup within a week of a supply cut will not delay production.
Keep an eye on SEBS price increases and the production schedule of the original manufacturer, giving a two-week advance warning. Signals for hydrogenation unit maintenance and a sharp rise in crude oil appear two weeks in advance. The contingency plan is updated once a year; don’t write one version and keep it for three years.
Temporarily sourcing materials during supply interruption is both expensive and may not be suitable. Production stoppage causes the greatest loss, and the hardness, peel strength, and compression of substitute materials need to be tested first. Don't wait until the production line stops to start making calls everywhere.
When supply is truly cut off, there isn’t enough time for verification, so you need to run through alternative materials in advance; it can’t be rushed. Keep an eye on SEBS price increases and the original factory’s production schedule to give early warnings so there’s time to switch materials. The contingency plan should be updated once a year, don’t write one and leave it for three years.
Temporarily sourcing materials is expensive and may not be suitable, causing the greatest production loss.
Having all three prepared, a supply cutoff won't cause panic; lacking even one, you'd be at a loss if the supply genuinely stops.
When the supply is truly cut off, there’s not enough time for verification, so normally the alternative materials need to be tested through in advance. You can’t rush it. Keep an eye on SEBS price increases and the original factory’s production schedule, and only an early warning allows you to switch materials in time.
Cologne Customer Case: Cost Overrun Leads to Soft Quotation, Custom Grade Returns to Budget Line
A modified material application factory in Qingdao found the cost of TPE parts exceeded the budget, making the quotation uncompetitive. Kolon cooperated to customize special grades with oil and temperature resistance, bringing the cost back within the budget and making the quotation competitive again. Customizing according to working conditions, if the cost exceeds the budget, first look at the formulation system.
