PBT又可称为热塑性聚酯塑料，为适用于不同加工业者使用，一般多少会加入添加剂，或与其它塑料掺混，随着添加物比例不同，可制造不同规格的产品。由于PBT具有耐热性、耐候性、耐药品性、电气特性佳、吸水性小、光泽良好，广泛应用于电子电器、汽车零件、机械、家用品等，而PBT产品又与PPE、PC、POM、PA等共称为五大泛用工程塑料。
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%，PBT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。PBT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。 PBT 结晶速度快，最适宜加工方法为注塑，其他方法还有挤出、吹塑、涂覆和各种二次加工成型，成型前需预干燥，水分含量要降至0.02%。聚对苯二甲酸丁二醇酯PBT的注塑工艺特性与工艺参数的设定：聚对苯二甲酸丁二醇酯(PBT)是通用的工程塑料。PBT的聚合工艺成熟、成本较低，成型加工容易。未改性PBT性能不佳，实际应用要对PBT进行改性，其中，玻璃纤维增强改性牌号占PBT的70％以上。
Expected to enhance environmental protection flame retardant PBT PBT payment cards
Supply Jiangsu Sanfangxiang PBT pay card 4308,4307, price of 18,500 yuan / ton.
May be called a PBT thermoplastic polyester plastic, as applied to different processing industries, the general number of additives are added, or blended with other plastics, with the proportion of different additives, can produce different specifications of the product. As the PBT has a heat resistance, weather resistance, chemical resistance, good electrical properties, low water absorption, good luster, widely used in electronic appliances, auto parts, machinery, household goods, etc., and PBT products but also with the PPE, PC, POM , PA, a total of five pan-called engineering plastics.
