PBT is the second most important commercial polyester. PBT is a semi-aromatic thermoplastic that can be easily molded and thermoformed. Depending on the cooling rate and molding process, it is either amorphous or semi-crystalline. PBT has many attractive properties like high strength and toughness, good abrasion and heat resistance, low creep at elevated temperatures, good chemical resistance, and excellent dimensional stability, particularly when glass-fiber reinforce.
PBT competes with PET in many engineering plastics applications. PBT has a slightly lower melting point but greater chain flexibility and crystallizes much faster than PET. PBT finds many uses as an engineering thermoplastic, particularly in electrical and automotive applications, including plug connectors, relays, keyboards, switches, distribution boxes, and fiber optic cable jackets.
