6.新型热塑性硫化橡胶TPV
随着动态硫化技术的发展，在通用型热塑性弹性体( EPDM/PP TPV) 的基础上，功能型 TPV 材料( 如轮胎用TPV、医用TPV 等) 的开发制备也成为该领域的研究热点。
介绍
热塑性弹性体，简称TPE或TPR，是Thermoplastic rubber的缩写。是常温下具有橡胶的弹性，高温下具有可塑化成型的一类弹性体。热塑性弹性体的结构特点是由化学键组成不同的树脂段和橡胶段，树脂段凭借链间作用力形成物理交联点，橡胶段是高弹性链段，贡献弹性。塑料段的物理交联随温度的变化而呈可逆变化，显示了热塑性弹性体的塑料加工特性。因此，热塑性弹性体具有硫化橡胶的物理机械性能和热塑性塑料的工艺加工性能，是介于橡胶与树脂之间的一种新型高分子材料，常被人们称为第三代橡胶。
自从1958 年Bayer公司制备出热塑性聚氨酯( TPU) 以来，TPE就得到了迅速发展，尤其是1963年苯乙烯类热塑性弹性体问世以后，关于热塑性弹性体的制备理论逐步得到完善，应用领域进一步扩大。
热塑性弹性体的主要用途
热塑性弹性体是介于橡胶与树脂之间的一种新型高分子材料，不仅可以取代部分橡胶，还能使塑料得到改性。热塑性弹性体所具有的橡胶与塑料的双重性能和宽广的特性，使之在橡胶工业中广泛用于制造胶鞋、胶布等日用制品和胶管、胶带、胶条、胶板、胶件以及胶粘剂等各种工业用品。

The structural characteristic of thermoplastic elastomers is that they consist of different resin and rubber segments composed of chemical bonds. The resin segment forms physical cross-linking points through the inter chain force, while the rubber segment is a highly elastic chain segment that contributes to elasticity.
