TPR材料 是什么?
TPR材料(Thermo-Plastic-Rubber material)是热塑性橡胶材料。是一类具有橡胶弹性同时无需硫化,可直接加工成型(如注塑,挤出,吹塑等)的热塑性软性胶料。
TPR材料是以热塑性丁苯橡胶(如SBS,SEBS)为基础原材料,添加树脂(如PP,PS),填料,增塑油剂以及其他功能助剂共混改性材料。TPR,这是多数用户对热塑性弹性体的称呼,而这类弹性体主要指苯乙烯类弹性体SBS,SEBS改性的材料。
扩展资料:
TPR与PVC都是具有橡胶弹性的软性材料,通过外观和手感很难鉴别出来。而通过燃烧区别则比较直观容易。
1、TPR燃烧有芳香的味道,味道不算难闻。PVC燃烧有氯的臭味,味道难闻。
2、燃烧时火焰根部颜色为绿色的是PVC材质,颜色为蓝色的是TPR材质。
3、PVC阻燃级别为UL94-V2,具有自熄性,点火燃烧,点火源撤离后,火焰一般会熄灭;TPR阻燃级别为UL94-HB,,遇火燃烧,离火续燃不熄灭。

tpr是什么材质?
TPR材料是一种热塑性橡胶材料,可直接加工成型,颜色为透明或本白色颗粒,具有良好的回弹性和良好的耐磨性,防滑性和减震性能优良,tpr舒适度要优于橡胶,抗疲劳性以及机械性能不如硫化橡胶。具有硬度特性,加工特性,环保特性。
这类材料兼有热塑性的加工成型特征和硫化橡胶的橡胶弹性性能。热塑性橡胶是在20世纪50年代初期出现的,但是1965年后才得到少许应用,目前国外热塑性橡胶的发展异常迅速,已构成一个新的工业原料体系,被称为“第三代橡胶”。

最早的TPE是聚氨酯橡胶(TPU),1958年由联邦德国法本拜耳公司试制成功。1963年,菲利浦石油公司首次生产了一种热塑性聚苯乙烯-聚丁二烯-聚苯乙烯嵌段共聚物(SBS);接着,1965年,美国壳牌化学公司除了生产SBS外,还增添了聚苯乙烯-聚异戊二烯-聚苯乙烯嵌段共聚物(SIS)。
70年代初,由尤尼罗伊尔公司开发了热塑性聚烯烃橡胶 (TPO);聚酯型TPE(CPE)也由杜邦公司首次实现了商品化。至70年代中期,已开发了20余种类型,200余种产品,生产厂家在100个以上。
