熱塑性彈性體TPE(Thermoplastic Elastomer) 是一種具有硫化橡膠的物理性能,又具有熱塑性塑料的加工性能特征的新一代環保材料,具有環保無毒安全,硬度范圍廣,有優良的著色性,觸感柔軟,耐候性,抗疲勞性和耐溫性,加工性能*,無須硫化,可以循環使用降低成本,可謂是塑料和橡膠優點的優勢組合,
TPE熱塑性彈性體正逐步占領PVC和橡膠的應用領地。主要原因在于橡膠氣味大,不可回收利用,不環保,耐油性、耐溶性比較差,不具備耐臭氧化性,電氣絕緣性差,不適宜作為絕緣材料,不易儲存,易老化,在低溫的情況下會變硬,穩定性差,密度大,加工時不易掌控。PVC—聚氯乙烯,是一種有毒的含氯樹脂。加工時添加了增塑劑,增塑劑的含量越大,材料越柔軟,廣泛的用于建材,人造皮革中。聚氯乙烯塑料制品在較高溫度下,如50℃左右就會慢慢地分解出對人體有害的氣體。
