摘要
聚氨酯 (PU )弹性体的耐热性能较差 ,限制了其使用范围的进一步拓宽。而经过纳米改性的 PU ,其力学性能和耐热性能都有所提高 ,效果良好 ,文章简要介绍了
The further opening of the application scope of polyurethane(PU) elastomer is restricted because of its poorer heat resisting property.After modifying,both mechanical properties and heat resisting property of PU are improved.This paper introduces briefly some methods for the modification of PU.
