Part I. TPE Introduction 1. Standard meaning of TPE According to ISO 1382 , Thermoplastic Elastomer is a polymer or a blend of polymers which needn\'t bother with vulcanisation or reticulation when handled, however exhibits comparable properties as vulcanized elastic at administration temperature. These properties vanish at handling temperature to permit the ulterior procedure conceivable, however return as the material comes back to working temperature. Multibase Korea
