1. Polybutylene terephthalate (PBT)
PBT can also be called thermoplastic polyester plastic. In order to be suitable for use by different processing industries, additives are generally added or mixed with other plastics. Different specifications of products can be manufactured according to the different proportions of additives. Because PBT has heat resistance, weather resistance, chemical resistance, good electrical properties, low water absorption, and good gloss, it is widely used in electronic appliances, auto parts, machinery, household products, etc., and PBT products are collectively called the five major general-purpose engineering plastics together with PPE, PC, POM, PA, etc.
2. Advantages
Excellent mechanical properties, especially high rigidity and hardness. Good heat resistance, heat deformation temperature can reach above 180℃. Good surface gloss, especially suitable for spray-free electronic and electrical products. Faster crystallization speed, good fluidity, excellent formability. Good thermal stability, especially low thermal expansion rate and dimensional shrinkage rate. Good resistance to chemicals, solvents, and weathering. High dielectric strength, good electrical properties. Low hygroscopicity, minimal effect on electrical and dimensional stability.
3. Disadvantages:
The molecule contains ester bonds, which will decompose under the action of strong acids, strong bases and water vapor. The material is more sensitive to gaps and is brittle.
4. Application scenarios
The application-related industries include automobiles, electronics/electrical appliances, and machinery:
Connectors
The connector is a bridge between signals and is an indispensable component for transmitting electronic signals and power connections. The balanced physical properties and price of PBT meet the needs of connectors. PBT is usually mixed with 30% glass fiber as a connector. PBT is widely used due to its mechanical properties, solvent resistance, good forming processability and low price. PBT cannot be used in SMT connect
