 1.TPE is type material? price relatively solid 定?

has use 户, electrical 话 就问, 你家TPE how much 钱一吨. 似乎TPE就 is that types material, but also property can comparison solid 定, price comparison solid 定一样. can upper, TPE包含 very multiple type type, 如TPU,TPV,TPEE,以 and 基于SEBS,SBS基材 TPR(TPE). TPE types type relatively more, non types material, price 自然不 can 随意报价.

another 顺便提 and, usually TPE, large more 指SEBS基础 modified elastomer TPE, this category of TPE也 has different hardness and material property, price according to requirements assessment .

2. has liquid 体TPE?

has use very soft products, or 者准备做一项 new product, processing 方便 考虑, can has liquid type TPE, 直接灌胶 solid molding. can upper, liquid 体TPE is has . liquid 体, is normal temperature tool has can flow property material 质. TPE normal temperature lower is solid elastic property pellets, usually need high temperature add hot 熔化才 can tool flow features.

3.TPE can substitute/replace PVC?

TPE and PVC versus ratio, 不含卤素, 不含邻苯塑化 agent, heavy metal, more is environmental protection safety .

TPE ratio PVC more tool has excellent low temperature resistance property. TPE ratio PVC触感 more 舒适爽 slip, wear resistance and slip property more excellent. this features, let has versus 信TPE can substitute/replace PVC.

can upper, application industry, if has relatively high environmental protection testing requirements, non use water tube/pipe, non use packaging bag and other, its can use PVC, is PVC ratio TPE price 便宜.

而实际情况 is, price 考虑, TPE in industry need substitute/replace PVC, still has process.

another from processing 方面考虑, PVC独 has 滴胶（ micro amount injection shot ） process, 搪胶 processing process , still is TPE can 想象 （ about/regarding 搪胶, tool has certain Model/Grade SEBS system TPE can simple processing ）.

4.TPE二次 injection molding （ overmolding ） adhesion good, is material issues?

overmolding is TPE important application, small 编经常遇 to use inquiry TPE overmolding viscous good issues. use 户第一 time 会怀疑定 is material issues. 当然, overmolding viscous good, is material issues this type of can can property has, its can can is injection molding using/adopting temperature degree 不够 致. different TPE材 material and overmolding hard plastics different, mold and product structure and other, as is molding temperature degree setting need factors .

5.TPE都 is food grade?

very more TPE厂家都宣传自己 TPE is food grade. this value 商榷, food grade is 商家 一 卖点 and 促销手段.

food grade standards is 一 笼统 concept, for/regarding different material 而言, has different testing standards. material food grade testing standards, USA FDA for/regarding TPE testing requirements is need water and positive testing （21CFR177.2600).

而 currently can meanwhile this testing TPE厂家 can is 凤毛麟角. TPE product application, although is use in is food related industry, due to application requirements that 么严格, need water testing, or RoHS, REACH can, that this category of food grade environmental protection testing requirements, TPE basic is can through.

但 if is recycled type TPE material, its environmental protection safety property full has 保障.
