Polybutylene terephthalate (PBT) is a thermoplastic polyester. Compared with other thermoplastic engineering plastics, non-reinforced PBT has better processability and electrical properties. The glass transition temperature of PBT is low, the mold temperature can be rapidly crystallized when the mold temperature is 50 °C, and the processing cycle is short. Polybutylene terephthalate (PBT) is widely used in the electronics, electrical and automotive industries.
