PBT (Polybutylene terephthalate)
PBT : Polybutylene terephthalate
CAS NO.: 26062-94-2
Capacity: 240kt/year
PBT is a high-performance thermoplastic engineering plastic made from PTA and BDO by a condensation reaction. It has excellent comprehensive performance and is widely used in industrial and consumer fields. PBT has become a key material for high-end manufacturing such as electronics and automobiles due to its heat resistance, chemical resistance, and easy processing. Through modification, the application scenarios can be further expanded to meet the industrial trend of lightweight and high performance.
