聚砜是一类新型热塑性工程塑料,它具有良好的热、电和抗机械性能,但对于化学试剂的抵抗能力较差,易产生环境应力开裂. 尼龙6是一类结晶性的热塑性树脂,具有优异的耐化学试剂能力,它的热扭变温度较低以及对水比较敏感等缺陷导致尼龙材料不能在较高温度下及电器装置的应用中使用.有人曾企图用共混聚砜和尼龙6以改进两者的性能,但实验结果表明无定形的聚
Polysulfones are a new class of thermoplastic engineering plastics that have good thermal, electrical and mechanical properties but are less resistant to chemical agents and prone to environmental stress cracking. Nylon 6 is a crystalline thermoplastic resin with Outstanding chemical resistance, low heat distortion temperature and sensitivity to water make nylon materials unsuitable for use at higher temperatures and in electrical installations Some attempts have been made to blend polysulfone and nylon 6 To improve the performance of both, but the experimental results show amorphous poly
