1.透明性TPU的透明性優(yōu)于TPE,同時(shí)它也沒(méi)有透明TPE那么容易沾粘。
2.比重TPE的比重變化范圍很大,從0.89~1.3之間的都有,而TPU在1.0~1.4之間。其實(shí)它們?cè)谑褂玫倪^(guò)程中,主要是以共混物的形式出現(xiàn),因此比重變化大。
3.耐油性TPU的耐油性較好,而TPE要做到耐油是有一定難度的。
4.燃燒后TPE燃燒有淡淡的芳香味,燃燒的煙比較少和淡。TPU燃燒則帶有一定的刺激性異味,燃燒時(shí)有茲茲的輕微爆炸聲。
5. 機(jī)械性能TPU的彈性及彈性恢復(fù)性能(耐屈撓抗蠕變性能)優(yōu)于TPE。主要是TPU的材料結(jié)構(gòu)為聚合物均相結(jié)構(gòu),屬于聚合物樹(shù)脂類。而TPE則是多組分共混而成的多相結(jié)構(gòu)聚集的合金材料。高硬度的TPE加工容易發(fā)生制品變形,而在所有硬度區(qū)間范圍內(nèi),TPU均表現(xiàn)出優(yōu)良的彈性,并且制品不易變形。
6.耐溫性TPE是 -60攝氏度~105攝氏度,TPU是 -60攝氏度~80攝氏度。
7.外觀手感對(duì)于一些包覆成型的產(chǎn)品,TPU材質(zhì)的產(chǎn)品,手感較為粗糙,摩擦阻力強(qiáng);而TPE材質(zhì)產(chǎn)品,則手感比較細(xì)膩柔和,摩擦性能較弱。
