PBT (Polybutylene Terephthalate) is a thermoplastic polyester, belonging to the category of engineering plastics.PBT has excellent mechanical, chemical and electrical properties, so it is widely used in automobiles, electrical and electronic appliances and consumer products.

      Main properties of PBT:
High strength and rigidity: PBT has excellent mechanical strength and rigidity, and can maintain good shape and dimensional stability under stress.
Heat resistance: PBT still has good physical properties in high temperature environments and is suitable for use in applications requiring heat resistance.
Chemical resistance: PBT has good resistance to a variety of chemicals (such as oil, fat, weak acids, alkalis and alcohols) and is not easily corroded.
Good electrical insulation properties: PBT has excellent electrical insulation properties, so it is widely used in the shells and internal parts of electronic and electrical products.
Low moisture absorption: PBT has a low water absorption rate, so its dimensional stability is good in humid environments.
Wear resistance and self-lubrication: PBT has a smooth surface and low coefficient of friction, which makes it suitable for making some sliding parts.
Good processability: PBT can be processed into various shapes by injection molding, extrusion and other processes, easy to mass production.

         Application of PBT:
Due to its excellent comprehensive performance, PBT is widely used in many industries, especially in applications requiring high heat resistance, chemical resistance and high precision. Typical applications include:
Automotive industry: automotive connectors, lamp housings, wiper parts, sensor housings, etc.
Electronic appliances: sockets, switches, appliance housings, connectors and motor parts, etc.
Household appliances: housings and internal parts of appliances such as washing machines, coffee makers, hair dryers, etc.
Fiber optics and cables: Due to its excellent electrical properties, PBT is commonly used in fiber optic sheaths, cable sheaths and the housings of electronic components.

        Limitations of PBT:
Poor impact resistance: PBT has relatively low toughness and is prone to brittle cracking at low temperatures.
Weathering resistance is average: unmodified PBT is susceptible to aging and performance degradation under long-term exposure to ultraviolet light.
Dimensional stability is reduced at high temperatures: Although PBT has good dimensional stability at room temperature, it is slightly deformed in extremely high temperature environments.

        Summarize:
PBT is a comprehensive performance of engineering plastics, especially for the need for high strength, abrasion resistance, chemical resistance, good insulation and dimensional stability of the application areas. Modified versions such as glass fiber reinforced and flame retardant further expand its use in demanding environments.
