Solvay Specialty Polymers Radel® R-7400 Polyphenylsulfone (PPSU)

Radel® R-7300 (for light colors) and R-7400 (for darker colors) polyphenylsulfone resins were developed specifically for aircraft interior applications, and through the use of a proprietary flame retardant package, offer low heat release, low smoke generation, and low toxic gas emissions. These resins comply with the FAA regulation 14CFR Part 25.853 Appendix F. In addition, they have excellent impact resistance and ESCR when exposed to fluids typically used by the aerospace industry, reducing the need for annealing or protective films.Features: Detergent Resistant; Flame Retardant; Good Chemical Resistance; Good Processing Stability; Good Toughness; High Flow; Low Smoke Emission; Low ToxicityUses: Aerospace Applications; Aircraft Applications; Aircraft InteriorsAdditional Properties: OSU Peak Heat Release Rate - FAR 25.853(d) < 55.0 kW/m²; OSU Total Heat Release - FAR 25.853(d) < 20.0 kW·min/m²; Smoke Density - ASTM F814 < 5.0 Ds; Smoke Density - ASTM F814 1.0 DsInformation provided by Solvay Specialty Polymers.
