Product Description


 Most of PBT resins are processed into blends. After modification with various additives and blending with other resins, good comprehensive properties such as heat resistance, flame retardancy, electrical insulation and good processing properties can be obtained. Widely used in electrical appliances, automobiles, aircraft manufacturing, communications, home appliances, transportation and other industries. For example, PBT modified by glass fiber can be used to manufacture electronic parts requiring high dimensional stability under high temperature conditions for a long time. PBT has high breakdown voltage and is suitable for making high voltage resistant parts. Due to its good fluidity in melting state, it is suitable for injection processing of electrical parts with complex structure, such as socket of integrated circuit, printed circuit board, computer keyboard, electrical switch, fuse, temperature control switch, protector, etc. Automobile bumper, carburetor, spark plug, oil supply system parts, igniter, etc. In the field of communication, PBT is widely used in integrated modules, terminal blocks, power tools, etc. of program-controlled telephones.
