Polybutylene terephthalate, also known as tetramethyl terephthalate. Hereinafter referred to as PBT. It is a polycondensation of terephthalic acid and 1, 4-butanediol. Together with PET, PBT is called thermoplastic polyester.
Characteristics of PBT
F. Molding processability: injection or extrusion of ordinary equipment. Due to the fast crystallization speed, good fluidity, mold temperature is also lower than other engineering plastics. When processing thin-walled parts, it only takes a few seconds, and it only takes 40-60s for large parts.
