PESU简介；

PESU聚砜类塑料是指大分子主链含有砜基及芳核的高分子化合物。它是一种线型热塑性工程塑料，具有优良的耐热性、耐氧化性、耐辐射性，以及电绝缘性、突出的抗蠕变能力和较高的物理力学性能，优良的耐化学腐蚀，除强溶剂、浓硫酸、硝酸以外对其他化学试剂（如无机酸碱盐等）稳定。按其主链分子结构的不同，聚砜类塑料有可分为聚砜、聚芳砜和聚醚砜。一般说，聚砜的热变形温度为175℃，可在-100℃--150℃之间长期使用，而且在高温下耐老化性能极好。聚芳砜是耐热工程塑料中最优秀的品种之一，其耐热性可与热固性耐高温的句聚酰亚胺媲美，负荷变形温度为275℃，长期使用温度为275℃，在-240℃--260℃能够保持良好的力学性能和电绝缘性能。聚醚砜的性能介于聚砜和聚芳砜之间负荷温度为203℃长期使用温度为-100℃--180℃。聚砜类塑料在潮湿的环境中仍然能够保持良好的电绝缘性能。
