For reference only
PBT GF30 is a composite material made by reinforcing Polybutylene Terephthalate (PBT) with 30% glass fiber.
It enhances mechanical strength, stiffness, and thermal resistance while maintaining good processability.
PBT-LGF offers good stiffness and toughness, while PET-LGF provides higher tensile strength and rigidity.
PBT has lower melting and Tg than PET, but performs well in moderate heat environments.
PBT has excellent insulation properties, especially suitable for electronic components.
PBT has good resistance to oils and hydrolysis; PET has better resistance to acids and bases.
PBT offers faster crystallization and shorter cycle times, improving production efficiency.
Automotive: connectors, housings, structural parts
Electrical & Electronics: switches, relays, sockets, insulation components
Industrial: mechanical housings, structural components
