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.

PBT has properties similar to those of PET (polyethylene terephthalate). It is known for its dimensional stability, low moisture absorption, high strength, stiffness, and chemical, UV, and thermal resistance. It is commonly used in automotive fenders and interior trim pieces, power tool housings, and electrical enclosures.

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.

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.
