三菱Novaduran系列PBT型号以及详细说明;
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。
PBT注塑
PBT注塑之前一定要在110~120℃的温度下干燥3小时左右,成型加工温度为250~270℃,模温控制在50~75℃为宜。因该料从熔融状态一经冷却,则会立即凝固结晶,故其冷却时间较短;若喷嘴温度控制不当(偏低),流道(水口)易冷却固化,会出现堵嘴现象。若料筒温度超过275℃或熔料在料筒中停留时间超过30分钟,易引起材料分解变脆。PBT注塑时需用较大水口进胶,不宜使用热流道系统,模具排气要良好,宜用“高速、中压、中温”的条件成型加工,防火料或加玻纤的PBT水口料不宜再回收利用,停机时需用PE或PP料及时清洗料管,以免碳化。
