Product Description

Polybutylene Terephthalate (PBT) Copolymer Pellets Product Description

   

        Polybutylene Terephthalate (PBT) is a high-performance semicrystalline thermoplastic polyester, synthesized by polycondensation of 1,4-butanediol and terephthalic acid (or dimethyl terephthalate). Our PBT plastic pellets feature excellent mechanical strength, heat resistance, chemical resistance, and electrical insulation properties, combined with outstanding processability. Supplied in uniform granular form, the product is compatible with standard plastic processing equipment such as injection molding, extrusion, and blow molding machines, making it widely applicable in automotive, electronics, electrical appliances, and industrial sectors.
