High-Heat Transparency with Superior Toughness and Impact Strength
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.
Why Radel® PPSU?
- High HDT of 207°C (405°F)
- Impact strength similar to PC
- Better chemical resistance than PEI
- Virtually unlimited steam sterilization
- Exceptional long-term hydrolytic stability
- Transparent and opaque colors
- Inherently UL-94 V0
Radel® PPSU offers long-lasting performance in healthcare, plumbing, food service, aircraft and wire insulation applications. Medical-grade Radel® PPSU resins have a long history of providing a strong, lightweight alternative to metal in sterilizable instrument trays, implant trials and surgical instrument handles. The material is biologically inert and BPA-free, making it suitable for food service applications. In plumbing, Radel® PPSU and Acudel® modified PPSU routinely replace brass in pressurized, hot water fittings and valves, thereby eliminating corrosion and contamination from heavy metals while extending service life. In Green Hydrogen, Radel® PPSU offers the superior strength and stability required for membrane electrode assembly components, such as subgaskets in fuel cell systems.
