PBT (Polybutylene Terephthalate)

Polybutylene Terephthalate (PBT) is a strong, crystalline thermoplastic polyester used as an engineering plastic for its excellent electrical insulation, dimensional stability, toughness (even at low temps), and resistance to heat and chemicals, making it ideal for auto parts, electrical connectors, and durable goods like keycaps. It's known for its high performance, good flow during moulding, and ability to be reinforced (e.g., with glass fibres) for even greater strength, but it has poor resistance to strong alkalis and certain solvents.

Key Properties & Characteristics
