TPS 苯乙烯类TPE （简称TPS）

苯乙烯类的TPE材料一般成为TPS。TPS又可细分为SEBS、SBS、SEPS 及 SEPS-V。凯柏胶宝主要生产的是SEBS（苯乙烯嵌段共聚物）材料。在这个材料中，苯乙烯尾段连接在一个弹性的区段（乙烯-丁烯），SEBS被使用在热熔连接或为双料注塑加工材料中软性的成分。

类別

聚合物依据他们网络的结构可分为四类：热塑性塑料、弹性体、热硬化性树脂以及热塑性弹性体（TPE）。热塑性塑料的结构是由分子间交互作用产生的微弱物理力支撑的单一面向聚合体链接组成。如果遇热或遇剪切力，则变成自由流体，可以被塑。 冷却后，材料会再度变硬。因为这个过程纯属物理反应，所以可以随时无限重复（如：聚丙烯）。热硬化性树脂是紧密交联的聚合物，遇高温也不会融化，可依旧维持其网络结构。在室温下，这种材料硬且易碎（如：环氧树脂）。而同时也被称为橡胶的弹性体，为化学交联具有弹性的结构，在硫化后不能被塑型，其大分子交联且盘绕。这种材料能够短暂地经压缩和压力被塑型， 在压力解除后立即恢复原有的组织（如：亚硝酸还原酶）。TPE包含热塑性塑料尾段（聚苯乙烯）及一个弹性的中间段（乙烯-丁烯）。这种结构使得此种材料能够自由流动且可被塑。待材料冷却后，物理交联的作用形成；将弹性段嵌入固体的3D网络中，TPE因此兼具弹性体及热塑性塑料的属性。

TPS styrene type TPE (TPS)
Styrene type TPE material generally become TPS.TPS can be subdivided into SEBS, SBS, SEPS and SEPS - V.Abraham kuyper glue treasure the main production of SEBS (styrene block copolymer) materials.In this material, styrene late connection in a section of an elastic (ethylene - butene), SEBS is used in hot melt connection or for double injection molding processing material soft component.
category
Polymers on the basis of their network structure can be divided into four categories: thermoplastic plastics, elastomers, thermosetting resins and thermoplastic elastomer (TPE).Structure of thermoplastics is produced by the interaction between the molecules of weak physical strength to support a single oriented polymer links.If or when it is heated in the shear stress, become free fluid, can be molded.After cooling, the material will harden again.Because this process is a purely physical reaction, can be repeated indefiniy (such as: polypropylene).Thermosetting resin is closely crosslinked polymer, when high temperature also won't melt, can still maintain its network structure.At room temperature, this kind of hard and brittle materials (such as epoxy resin).And at the same time, also known as rubber elastomer, as the chemical crosslinking of flexible structure, cannot be shaped after vulcanization, the macromolecular crosslinking and coiling.This material can be briefly by the compression and the pressure is to get fit, immediay after the pressure to restore the original organization (such as: nitrite reductase).TPE contains thermoplastic late (polystyrene) and an elastic in the middle of the paragraph (ethylene butene).This structure makes this kind of material can flow freely and can be molded.For material after cooling, the role of physical crosslinking form;Embedding elastic section of the solid 3 d network, TPE so both properties of elastomers and thermoplastics.
