PBT is a milky white translucent to opaque, crystalline thermoplastic polyester. It has high heat resistance, toughness, fatigue resistance, self-lubrication, low friction coefficient, low weather resistance, low water absorption, only 0.1%, and maintains various physical properties (including electrical properties) and electrical insulation in a humid environment. However, the dielectric loss is large. Heat-resistant water, alkalis, acids, oils, but susceptible to attack by halogenated hydrocarbons, poor hydrolysis resistance, rapid crystallization at low temperatures, good moldability. PBT has a fast crystallization speed. The most suitable processing method is injection molding. Other methods include extrusion, blow molding, coating and various secondary processing. Pre-drying is required before molding, and the moisture content should be reduced to 0.02%. PBT (enhanced, modified PBT) is mainly used in automotive, electronic appliances, industrial machinery and polymer alloys, blending industries. For example, as a distributor in a car, a body part, an igniter coil bobbin, an insulating cover, an exhaust system component, a motorcycle igniter, a deflection yoke such as a television set in an electronic appliance industry, a picture tube and a potentiometer bracket, with sound output Transformer frame, adapter frame, switch connector, electric fan, refrigerator, washing machine motor end cover, bushing.
