TPEE热塑弹性体材料4047
TPEE 优点:
TPEE是什么材料:热塑性聚酯弹性体TPEE作为热塑性工程塑料较新的成员,完美的结合了橡胶的弹性,工程塑料的强度及热塑料的加工特性。区别于传统弹性体TPE,聚酯弹性体TPEE拥有三大特点:(1) 突出的物理、化学性能:拥有惊人的回弹力,出众的韧性及强度。对蠕变、冲击和挠曲疲劳具极高抗力。在埃佐( Izod ) 缺口冲击强度试验中(ASTM 标准D256) , - 40 ℃以及23 ℃的情况下保持不破;低温下3 万次的弯折试验不断;塑料中拥有最类似弹簧的特性。同时,聚酯弹性体可抵抗非极性溶剂(油、燃油、液压油) , 室温下的极性溶剂(乙二醇、高分子量乙醇、弱酸和弱碱) 。TPEE可以反复的利用。
