Solvay Radel PPSU R-5100 NT/CL301/BU501/BK937/NT15/GY1137/GY1037/GY874 Polyphenylsulfone Resin

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) with 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

Radel® R-5100 polyphenylsulfone is an amorphous thermoplastic material that offers exceptional hydrolytic stability and toughness superior to other commercially available, high-temperature films.

PPSU films have high deflection temperatures and outstanding resistance to environmental stress cracking. The polymer is inherently flame retardant. The excellent thermal stability makes films suitable for applications where very low shrink at high temperatures are needed. PPSU films also have good electrical properties.
