三菱PBT Novaduran特性
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。
机械性能:强度高、耐疲劳性、尺寸稳定、蠕变也小(高温条件下也极少有变化);
耐热老化性:增强后的UL温度指数达120~140℃(户外长期老化性也很好);
耐溶剂性:无应力开裂;
对水稳定性:PBT遇水易分解(高温、高湿环境下使用需谨慎);
电气性能:
1、绝缘性能:优良(潮湿、高温也能保持电性能稳定,是制造电子、电器零件的理想材料);
2、介电系数:3.0-3.2;
3、耐电弧性:120s
成型加工性: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塑料要求低。在加工薄壁制件时,仅需几秒钟,对大部件也只要40-60s即可。
