Quick Information

  • Place of Origin: China


PBT (Polybutylene terephthalate) is a thermoplastic engineering polymer that is widely used in the electrical and electronic industries. It is a thermoplastic (semi-)crystalline polymer, and a type of polyester. PBT is resistant to solvents, shrinks very little during forming, is mechanically strong, heat-resistant up to 150 oC (or 200 oC with glass fiber reinforcement) and can be modified with flame retardant additives to make it noncombustible. 

PBT is closely related to other thermoplastic polyesters. Compared to PET (Polyethylene terephthalate), PBT has slightly lower strength and rigidity, slightly better impact resistance, and a slightly lower glass transition temperature. PBT and PET are sensitive to hot water above 60 oC (140 oF). PBT and PET need UV protection if used outdoors, and most grades of these polyesters are flammable, although additives can be used to improve both UV and flammability properties.


UNINKO modified PBT & PET compounds series includes flame retardant grade, glass fiber/mineral reinforced grade, laser engraving  grade, etc broad range, with excellent performances, and widely used in electrical and electronics, automobile, home appliances and other industries, etc.
