​Polybutylene terephthalate (PBT)

​Polybutylene Terephthalate (PBT) is a thermoplastic engineering polymer known for its high strength, stiffness, and excellent resistance to heat and chemicals. It is commonly used in precision-molded parts, particularly in the automotive and electrical industries. PBT has a low friction coefficient, good dimensional stability, and superior insulating properties, making it a go-to material for high-performance applications. It also exhibits good resistance to moisture and wear, ensuring durability in harsh environments. Its properties make PBT highly suitable for high-stress and high-temperature applications, contributing to its widespread use across various industries.​​

 

Some of its applications:- 

​

1. Automotive: PBT is used for parts like connectors, door handles, and mirror housings due to its heat resistance, toughness, and durability.

2. Electrical & Electronics: Due to its excellent electrical insulating properties, PBT is widely used in connectors, switches, and circuit boards.

3. Appliances: PBT is used in small appliance parts like hairdryer housings and microwave components because of its heat resistance and dimensional stability.

4. Industrial machinery: PBT is employed in gears, bearings, and other mechanical parts that require low friction and high durability.
