PPS is a high-performance, tough engineering plastic with great dimensional and thermal stability, as well as a wide operating temperature range of up to 260 °C and good chemical resistance. Moreover, PPS, like most other thermoplastics, is an electrical insulator. Its ability to be used at high temperatures coupled with its thermal stability makes PPS great for applications such as semiconductor components in machinery, bearings, and valve seats.

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.

Due to its excellent mechanical properties, thermoplastic carbon fiber is widely used in the automotive field of fuel system components, sensors, shell components. It is because of the high strength and stiffness of PPS-LCF, and the finished parts are not easy to damage. PPS-LCF also has a relatively low coefficient of thermal expansion to ensure the stability of the finished product.
