PBT简介:
pbt中文名为:聚对苯二甲酸丁二醇酯,英文名polybutylene terephthalate(简称PBT),属于聚酯系列,是由1.4-pbt丁二醇(1.4-Butylene glycol)与对苯二甲酸(PTA)或者对苯二甲酸酯(DMT)聚缩合而成,并经由混炼程序制成的乳白色半透明到不透明、结晶型热塑性聚酯树脂。与PET一起统称为热塑性聚酯,或饱和聚酯。热塑性聚酯树脂聚对苯二甲酸丁二酯(PBT),吸水率小于0.1%,摩擦系数低,而且耐磨。PBT是结晶性聚合物,经玻璃纤维增强后,不仅热变形温度得到很大的提高,其力学性能的各种强度都可成倍地增长,而且比同样条件下的MPPO、POM、PC的各种强度都好,增强PBT具有突出的动态力学性能。PBT耐化学试剂性能优越,常温下几乎能耐除强酸、强碱外的其他化学试剂。
PBT特性:
优秀的机械强度
良好的耐热性
吸水率特别少,尺寸稳定性好
耐油性、耐溶剂性好
电气性能优良
主要应用领域
PBT是一种结晶性树脂,结晶化速度很快,成型性特别好,并且耐热性、耐药品性、电气的特性优秀,使用于制造各种电子制品的配件。
