Radel polyphenylsulfone (PPSU) delivers the highest performance of our sulfone polymers. Our broad product slate offers an impressive selection of transparent and opaque color and meets a wide range of performance, price and processing requirements.

Radel PPSU offers impact strength similar to polycarbonate (PC) and better chemical resistance than polyetherimide (PEI). It excels in high heat and humidity environments and provides operating temperatures around 200°C (392°F) and inherent flame retardant properties.

Radel R-5100 is an opaque, General Purpose polyphenylsulfone (PPSU) for injection molding, that offers exceptional hydrolytic stability, and toughness superior to other commercially-available, high-temperature engineering resins. This resin also offers a high deflection temperature and outstanding resistance to environmental stress cracking. Radel polymers are inherently flame retardant, provide excellent thermal stability and possess good electrical properties.
