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.

Polyphthalamide (PPA) is a semicrystalline, aromatic polyamide. It is in the polyamide, or nylon, family. Compared to Nylon 6/6, it is stronger, stiffer, less sensitive to moisture, and has higher thermal capabilities. In addition, it has significant resistance to chemical fatigue and mechanical creep.

Fiber-reinforced PPA has high temperature resistance, high strength and low density, so it is considered the best resin to replace steel with plastic in the future. It can be used in many industrial and civil fields, including automobiles, equipment, entertainment, food processing, communications, electronics and electrical , power tools, gardening, etc.
