Polybutylene Terephthalate (PBT), a semi-crystalline engineering-grade thermoplastic that is part of the polyester family, combines excellent mechanical and electrical properties with robust chemical resistance. It was first introduced by Ticona as Celanex® PBT.

PBT is a white or off-white polyester. Unreinforced grades offer performance typical of a crystalline polymer, and are often used in applications when low moisture absorption, resistance to staining, or resistance to cleaning chemicals is required.

Several formulations, i.e., glass-filled, mineral filled, lubricant filled and variants within these grades such as FDA compliant, flame retardant, impact modified, UV resistant are available to meet specific application demands. Contact an Emco Industrial Plastics representative who can help you choose the correct material to meet the needs of your application.
