Most of the PBT resin is processed into compounding materials, modified by various additives, and blended with other resins to obtain good comprehensive properties such as heat resistance, flame retardancy, and electrical insulation, as well as good processing properties. It is widely used in electrical appliances, automobiles, aircraft manufacturing, communications, home appliances, transportation and other industries. For example, after PBT is modified by glass fiber, it can be used to manufacture electronic parts that require long-term high temperature working conditions and high dimensional stability. PBT has a high breakdown voltage and is suitable for the production of high-voltage resistant parts. Due to its good fluidity in the molten state, it is suitable for injection processing of electrical parts with complex structures, such as integrated circuit sockets, printed circuit boards, computer keyboards, and electrical switches , Fuses, temperature control switches, protectors, etc. Automobile bumpers, carburetors, spark plugs, fuel supply system parts, igniters, etc. In the communication field, PBT is widely used in integrated modules, wiring boards, power tools, etc. of program-controlled telephones.
