        PBT 聚对苯二甲酸丁二醇酯化学和物理特性:
PBT是最坚韧的工程热塑材料之一,它是半结晶材料,有非常好的化学稳定性、机械强度、电绝缘特性和热稳定性。这些材料在很广的环境条件下都有很好的稳定性。 PBT吸湿特性很弱。非增强型PBT的张力强度为50MPa,玻璃添加剂型的PBT张力强度为170MPa。玻璃添加剂过多将导致材料变脆。PBT的;结晶很迅速,这将导致因冷却不均匀而造成弯曲变形。对于有玻璃添加剂类型的材料,流程方向的收缩率可以减小,但与流程垂直方向的收缩率基本上和普通材料没有区别。一般材料收缩率在1.5%~2.8%之间。含30%玻璃添加剂的材料收缩0.3%~1.6%之间。熔点(225℃)和高温变形温度都比PET材料要低。维卡软化温度大约为170℃。玻璃化转换温度(glass trasitio temperature)在22℃到43℃之间。由于PBT的结晶速度很高,因此它的粘性很低,塑件加工的周期时间一般也较低。
