●高回彈性 將TPEE材料應(yīng)用到彈簧中，可使彈簧具有很長(zhǎng)的使用壽命，能夠幫助火車很平穩(wěn)地啟動(dòng)、加速、減速以及停止等。和金屬?gòu)椈伤煌氖?，它不?huì)生銹、也不會(huì)在自然環(huán)境條件下發(fā)生惡化、或者造成彈性破裂和損失等。而與橡膠材料相比，具有更大的重復(fù)使用性，還能保持很好的彈性。
●加工成型性 TPEE具有優(yōu)良的熔融穩(wěn)定性和充分的熱塑性，故而具有良好的加工性，可采用各種熱塑性加工工藝進(jìn)行加工，如擠出、注射、吹塑、旋轉(zhuǎn)模塑及熔融澆鑄成型等。在低剪切速率下，TPEE熔體粘度對(duì)剪切速率不敏感，而在高剪切速率下，熔體粘度隨剪切速率升高而下降。由于TPEE熔體對(duì)溫度十分敏感，在10℃變化范圍內(nèi)，其熔融粘度變化幾倍至幾十倍，因此成型時(shí)應(yīng)嚴(yán)格控制溫度。
