TPU作为弹性体是介于橡胶和塑料之间的一种材料,这从它的刚性看出来,TPU的刚性可由弹性模量来度量。橡胶的弹性模量通常在1~10Mpa,TPU在10~1000Mpa,塑料(尼龙,ABS,PC,POM)在1000~10000Mpa。TPU 的硬度范围相当宽,从Shore A 60~Shore D 80并且在整个硬度范围内具有高弹性;TPU在很宽的温度范围内-40~120℃,具有柔性,而不需要增塑剂; TPU对油类(矿物油,动植物油脂和润滑油)和许多有良好的抵抗能力;TPU 还有良好的耐天候性,极优的耐高能射线性能。众所周知的耐磨性,抗撕裂性,屈扰强度都是优良的;拉伸强度高,伸长率大,长期压缩变形率低等都是TPU的显著优点。 这里介绍的TPU性能包括三个方面:力学性能,物理性能和环境性能。 可加热塑化,化学结构上没有或很少交联,其分子基本是线性的,然而却存在一定的物理交联。这类聚氨酯称为TPU 。
