摘要
指出影响PU 弹性体耐热性能的主要因素有软段( 聚酯、聚醚) 、二异氰酸酯、扩链剂、硬段浓度、温度、时间及介质( 包括气体、水、油) 对PU 弹性体高温下和高温老化后某些力学性能的影响。
A review is cited with 20 references.Effects of soft segment (polyester and polyether),diisocyanated,chain extenders,concentration of hard segment,temperature,time and mediums (steam,air and oil) on heating property and heat aging property of polyurethane elastomer were discussed.
