PBT Plastic | Long Glass Fiber Reinforced PBT (PBT-LGF) What is PBT? Polybutylene terephthalate (PBT) is a semi-crystalline engineering thermoplastic polyester. It is produced via polycondensation of 1,4-butylene glycol and terephthalic acid (PTA) or dimethyl terephthalate (DMT), forming a milky white translucent to opaque resin. PBT exhibits excellent mechanical strength, chemical resistance, thermal stability, and electrical insulation properties, making it ideal for demanding engineering applications. Basic Properties of PBT Specific gravity: 1.31 g/cm³ Melting point: 225~275°C Glass transition temperature (Tg): 22–43°C Rockwell hardness (R scale): 118 Water absorption: 0.34% Molding shrinkage: 1.7~2.3% PBT-LGF | Long Glass Fiber Reinforced PBT PBT-LGF combines PBT with long glass fibers, improving mechanical strength, fatigue resistance, dimensional stability, and creep resistance. These properties are maintained even under high-temperature conditions. Advantages of PBT-LGF Excellent mechanical strength and fatigue resistance High heat resistance: UL temperature index 120–140°C Good solvent resistance and no stress cracking Easy flame-retardant processing: UL94 V-0 achievable Excellent electrical insulation: high resistivity, dielectric strength, arc resistance Good molding and secondary processing: injection molding and extrusion Fast crystallization and good fluidity: thin walls can be processed in seconds PBT-LGF Technical Data Sheet (TDS) Applications of PBT-LGF Long glass fiber reinforced PBT is widely used in electronics, automotive, and industrial applications due to its high mechanical strength, heat resistance, electrical insulation, and dimensional stability. Electronics: fuse-less wire breakers, electromagnetic switches, transformers, appliance handles, connectors, housings Automotive: door handles, bumpers, distributor covers, fenders, wire guard shells, wheel covers Industrial parts: OA fans, keyboards, fishing reels, lampshades, and other mechanical components Processing of PBT-LGF PBT-LGF can be easily processed via injection molding or extrusion using standard equipment. Due to fast crystallization and good fluidity, mold temperatures are lower than other engineering plastics, enabling rapid processing of both thin-walled and large parts.

Adding glass fiber to PBT is a commonly used method to enhance and modify PBT. The bonding force between glass fiber and PBT resin is good. After adding a certain amount of glass fiber to PBT resin, it can not only maintain the original advantages of PBT resin such as chemical resistance and processability, but also greatly improve its mechanical properties and overcome the problems.

PBT Long Glass Fiber Reinforced Material offers excellent dimensional stability, high strength, and outstanding chemical resistance. It is ideal for structural components requiring durability, heat resistance, and long-term mechanical performance.

One of the remarkable features of PBT-GF is its excellent dimensional stability. The presence of glass fibers greatly reduces the material's tendency to expand or contract under varying temperature conditions. This property ensures that PBT GF retains its shape and size, making it suitable for applications that demand tight tolerances and precise dimensions.

Polyphthalamide is a high-performance resin and member of the nylon family with exceptional thermal, mechanical, and physical properties. It is hygroscopic, opaque, semicrystalline, and can be used in plastic injection molding. Most PPA are filled with glass fiber or carbon fiber to enhance stiffness for high-temperature applications. As a result, PPA is often used in applications in place of metal or higher-priced thermoplastic.
