TPE塑膠原料的特點:
熱塑性彈性體TPE(Thermoplastic Elastomer) 是一種具有橡膠的高彈性,高強度,高回彈性,又具有可注塑加工的特征的材料。具有環(huán)保無毒安全,硬度范圍廣,有優(yōu)良的著色性,觸感柔軟,耐候性,抗疲勞性和耐溫性,加工性能優(yōu)越,無須硫化,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,也可以單獨成型。
Elexar、 Medalist和Monprene也將進一步擴大產(chǎn)品業(yè)務(wù)范圍,用以銷售TPE產(chǎn)品。其中,應用于電器、電子領(lǐng)域的TPE產(chǎn)品將被冠以Elexar品牌進行銷售,而醫(yī)用及日用TPE產(chǎn)品將分別被歸為Medalist和Monprene旗下。
