TPS 苯乙烯類TPE （簡(jiǎn)稱TPS）
苯乙烯類的TPE材料一般成為TPS。TPS又可細(xì)分為SEBS、SBS、SEPS 及 SEPS-V。凱柏膠寶主要生產(chǎn)的是SEBS（苯乙烯嵌段共聚物）材料。在這個(gè)材料中，苯乙烯尾段連接在一個(gè)彈性的區(qū)段（乙烯-丁烯），SEBS被使用在熱熔連接或?yàn)殡p料注塑加工材料中軟性的成分。
類別
聚合物依據(jù)他們網(wǎng)絡(luò)的結(jié)構(gòu)可分為四類：熱塑性塑料、彈性體、熱硬化性樹(shù)脂以及熱塑性彈性體（TPE）。熱塑性塑料的結(jié)構(gòu)是由分子間交互作用產(chǎn)生的微弱物理力支撐的單一面向聚合體鏈接組成。如果遇熱或遇剪切力，則變成自由流體，可以被塑。 冷卻后，材料會(huì)再度變硬。因?yàn)檫@個(gè)過(guò)程純屬物理反應(yīng)，所以可以隨時(shí)無(wú)限重復(fù)（如：聚丙烯）。熱硬化性樹(shù)脂是緊密交聯(lián)的聚合物，遇高溫也不會(huì)融化，可依舊維持其網(wǎng)絡(luò)結(jié)構(gòu)。在室溫下，這種材料硬且易碎（如：環(huán)氧樹(shù)脂）。而同時(shí)也被稱為橡膠的彈性體，為化學(xué)交聯(lián)具有彈性的結(jié)構(gòu)，在硫化后不能被塑型，其大分子交聯(lián)且盤繞。這種材料能夠短暫地經(jīng)壓縮和壓力被塑型， 在壓力解除后立即恢復(fù)原有的組織（如：亞硝酸還原酶）。TPE包含熱塑性塑料尾段（聚苯乙烯）及一個(gè)彈性的中間段（乙烯-丁烯）。這種結(jié)構(gòu)使得此種材料能夠自由流動(dòng)且可被塑。待材料冷卻后，物理交聯(lián)的作用形成；將彈性段嵌入固體的3D網(wǎng)絡(luò)中，TPE因此兼具彈性體及熱塑性塑料的屬性。
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.
