High temperature resistant imported PBT rod PPS board PI rod PAI board PBI rod

< >Product name:
Added glass fiber B, polybutylene terephthalate, (referred to as B), B 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, and low water absorption rate of only .%. It still maintains various physical properties (including electrical properties) and electrical insulation in humid environments. However, the volume resistance and dielectric loss are large. Resistant to hot water, alkalis, acids, and oils, but susceptible to corrosion by halogenated hydrocarbons, poor hydrolysis resistance, rapid crystallization at low temperatures, and good formability. The disadvantages are low notched impact strength and large molding shrinkage. Therefore, most of them are modified with glass fiber reinforcement or inorganic filling. Their tensile strength and bending strength can be more than doubled, and the heat distortion temperature is also greatly increased. It can work at
℃
Mainly used in automobiles, electronic appliances, industrial machinery, polymer alloys, and blending industries. Such as distributors, car body parts, ignition coil bobbins, insulating covers, exhaust system parts, motorcycle igniters, and electronic and electrical industries such as TV deflection coils, picture tubes and potentiometer brackets, Audio output transformer skeleton, adapter skeleton, switch connector, electric fan, refrigerator, washing machine motor end cover, bushing. In addition, there are transportation machinery parts, sewing machine and textile machinery parts, watch casings, mirror barrels, electric iron covers, mercury lampshades, baking oven parts, power tool parts, shielding sleeves, etc.
