PBT树脂原料
特点： PBT是一种乳白色半透明至不透明的结晶热塑性聚酯。它具有高耐热性、韧性、抗疲劳性、自润滑性、低摩擦系数、耐候性、低吸水性，仅为0.1%，在潮湿环境中仍保持各种物理性能（包括电气性能），电气绝缘，但介电损耗大。耐热水、碱、酸和油，但易被卤代烃侵蚀，耐水解性差，低温下可快速结晶，成型性好。PBT结晶速度快，最合适的加工方法是注射成型。其他方法包括挤压、吹塑、涂层和各种二次加工成型。成型前需进行预干燥，含水率应降至0.02%。PBT（增强、改性PBT）主要用于汽车、电子电器、工业机械及聚合物合金、共混等行业。如汽车经销商、车身零件、点火线圈骨架、绝缘罩、排气系统零件、摩托车点火器、电子电气行业电视机偏转线圈、显像管和电位器支架、声音输出变压器框架、适配器框架、开关连接器、电风扇、冰箱、洗衣机电机端盖、套管等

Product Details
PBT Resin Raw Material
Polybutylene terephthalate, referred to as PBT, belongs to the polyester series. Processed milky translucent to opaque, crystalline thermoplastic polyester resin. Together with PET, it is collectively referred to as thermoplastic polyester, or saturated polyester.
Features:
PBT is a milky white translucent to opaque, crystalline thermoplastic polyester. It has high heat resistance, toughness, fatigue resistance, self-lubrication, low friction coefficient, weather resistance, low water absorption, only 0.1%, and still maintains various physical properties (including electrical properties) in a humid environment, electrical insulation, But the dielectric loss is large. It is resistant to hot water, alkalis, acids and oils, but is easily eroded by halogenated hydrocarbons, has poor hydrolysis resistance, can be rapidly crystallized at low temperatures, and has good formability. PBT has a fast crystallization speed, and the most suitable processing method is injection molding. Other methods include extrusion, blow molding, coating and various secondary processing molding. Before molding, pre-drying is required, and the moisture content should be reduced to 0.02%. PBT (enhanced, modified PBT) is mainly used in automobiles, electronic appliances, industrial machinery and polymer alloys, blending industries. Such as distributors in automobiles, car body parts, igniter coil skeletons, insulating covers, exhaust system parts, motorcycle igniters, deflection coils of TV sets in the electronic and electrical industry, picture tubes and potentiometer brackets, sound output Transformer frame, adapter frame, switch connector, electric fan, refrigerator, washing machine motor end cover, bushing.
