Solvay Radel R-5000/R-5500/R-5600/R-5800/R-5900 Polyphenylsulfone Resin R-Series Virgin Pellet

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 colors 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.

• 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

Additional Radel grades include a transparent injection molding grade (R-5000), an opaque general purpose injection molding grade (R-5100), and a transparent extrusion grade (R-5500).
