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(TPA)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。
⒈优良的机械性能,机械强度高,耐疲劳性和尺寸稳定好。蠕变也小,这些性能在高温条件下也极少有变化。
⒉生产PBT所消耗的能量是工程塑料中最低的的,这对于世界范围内能源紧缺的情况下,具有十分重要的意义。
⒊耐热老化性优异,增强后的UL温度指数达到120~140℃,此外,户外长期老化性也很好。
⒋耐溶剂好,无应力开裂。
⒌PBT易于阻燃,可达UL94V-0级,由于与阻燃剂亲和性能好,所以容易开发反应型或添加型的阻燃品级。阻燃产品在电子电器工业中获得广泛应用。
⒍PBT遇水易分解,在高温、高湿环境下使用需谨慎。
⒎优良的电气性能,体积电阻率及介电强度高,耐电弧性优良,吸湿性极小,在潮湿及高温环境下,也能保持电性能稳定,是制造电子、电器零件的理想材料。
⒏易成型加工和二次加工,易用普通设备注塑或挤塑。由于结晶速度快,流动性好,模具温度也比其他工程材料要求低,在加工薄壁制件时仅需几秒钟,对大部件也只需40-60s即可。
PBT中文名称聚对苯二甲酸丁酯,简称饱和聚酯,系高结晶性热可塑性塑料。
优点:1、机械性质安定抗张强度与抗张模数和尼龙相似;2、摩擦系数小有自润性;
3、吸水率低;4、电气性质优良;5、尺寸安定性良好;6、耐药品性、耐油性极佳。
用途:1、电子电器:无熔线断电器、电磁开关、驰返变压器、家电把手、连接器、外壳等;
2、汽车:车门把手、保险杆、分电盘盖、挡泥板、导线护壳、轮圈盖等;
3、工业零件:OA风扇、键盘、钓具卷线器、零件、灯罩等。
特点: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 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%。PBT(增强、改性PBT)主要用于汽车、电子电器、工业机械和聚合物合金、共混工业。如作为汽车中的分配器、车体部件、点火器线圈骨架、绝缘盖、排气系统零部件、摩托车点火器、电子电器工业中如电视机的偏转线圈,显像管和电位器支架,伴音输出变压器骨架,适配器骨架,开关接插件、电风扇、电冰箱、洗衣机电机端盖、轴套.
