熱塑性彈性體TPE
國(guó)內(nèi)一般叫“TPE”材料,基本上屬于苯乙烯類熱塑性彈性體。苯乙烯類TPE(國(guó)外稱TPS),為丁二烯或異戊二烯與苯乙烯嵌段型的共聚物,性能接近SBR橡膠。
優(yōu)點(diǎn):具有橡膠的高彈性,又具有可注塑加工的特征;環(huán)保無(wú)毒安全,有優(yōu)良的著色性,觸感柔軟,耐候性,抗疲勞性和耐溫性,加工性能*,無(wú)須硫化,可以循環(huán)使用降低成本,既可以二次注塑成型,與PP、PE、PC、PS、ABS等基體材料包覆粘合,也可以單獨(dú)成型。
缺點(diǎn):SBS和SIS的問(wèn)題是耐熱性差,使用溫度一般不能超過(guò)80℃。同時(shí),其強(qiáng)伸性、耐候性、耐油性、耐磨性等也都無(wú)法同橡膠相比。
