Polysulfone (PPS) is a new type of high-performance thermoplastic resin, featuring high mechanical strength, high-temperature resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties.PPS is a high-performance specialty engineering plastic. It boasts excellent high-temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced physical and mechanical properties, and superior dimensional stability, as well as good electrical properties. Widely used as a structural high polymer material, PPS is also extensively employed as a specialty engineering plastic after being filled or modified. Additionally, it can be formed into various functional films, coatings, and composites, achieving successful applications in electronic appliances, aerospace, automotive transportation, and other fields.
