PBT材料简介：
聚对苯二甲酸丁二醇酯，英文名polybutylece terephthalate（简称PBT），属于聚酯系列，是由1.4-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。
PBT理化特性
PBT为乳白色半透明到不透明、结晶型热塑性聚酯。具有高耐热性、韧性、耐疲劳性，自润滑、低摩擦系数，耐候性、吸水率低，仅为0.1%，在潮湿环境中仍保持各种物性（包括电性能），电绝缘性，但体积电阻、介电损耗大。耐热水、碱类、酸类、油类、但易受卤化烃侵蚀，耐水解性差，低温下可迅速结晶，成型性良好。缺点是缺口冲击强度低 ，成型收缩率大 。故大部分采用玻璃纤维增强或无机填充改性，其拉伸强度、弯曲强度可提高一倍以上，热变形温度也大幅提高。可以在140℃下长期工作，玻纤增强后制品纵、横向收缩率不一致，易使制品发生翘曲。
可提供原厂物理性能表，UL黄卡，COC，SGS等资料！欢迎来电咨询洽谈！
