Advantages and Disadvantages of PBT Plastic Materials

Advantages:

1. Excellent mechanical properties with high rigidity and hardness
2. Good heat resistance, with a heat distortion temperature exceeding 180°C
3. High-gloss surface finish, suitable for unpainted electronic and electrical products
4. Fast crystallization, good flowability, and excellent molding properties
5. Low thermal expansion and shrinkage, ensuring dimensional stability
6. Resistance to chemicals, solvents, and weathering
7. High dielectric strength and good electrical insulation
8. Low water absorption, minimizing effects on electrical and dimensional properties
9. Disadvantages:
10. Susceptibility to decomposition in strong acids, alkalis, or steam due to ester bonds in its molecular structure
11. Notch sensitivity and potential brittleness under certain conditions
