Solvay Specialty Polymers Radel® R-7300 Polyphenylsulfone (PPSU), Premium grade
Categories: Polymer; Thermoplastic; Polyphenylsulfone (PPSU)

Material Notes: Premium grade, high flow for injection molding, suitable for light colors, for aircraft interiors

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.

Radel® R-7300 and R-7400 resins have excellent flow characteristics, readily filling complex parts with thin walls or long flow lengths.

Chemical Resistance:
One of the outstanding characteristics of Radel® R-7300 and R-7400 resins is their resistance to many commonly used aviation fluids. Three test methods: unstressed immersion, stressed with a 5-inch radius curve, and stressed with a variable radius curve fixture, were employed to evaluate resistance of Radel® resins to Skydrol® LD-4; 1,1,1-trichloroethane; Jet fuel A; methyl ethyl ketone; toluene; isopropanol; and Skydrol® 500B.

- Available in various custom colors

Markets/Uses: Aircraft / Aircraft Interiors / Air Vents and Return Grilles; Aircraft / Aircraft Interiors / Infill Panels; Aircraft / Aircraft Interiors / Oxygen Boxes; Aircraft / Aircraft Interiors / Passenger Service Units; Aircraft / Aircraft Interiors / Video Shrouds; Aircraft / Aircraft Interiors / Window Reveals and Shades

Applications: Aerospace Applications; Aircraft Applications; Aircraft Interiors

Features: Chemical Resistant; Detergent Resistant; Flame Retardant; Good Processing Stability; Good Toughness; High Flow; Low Smoke Emission; Low Toxicity

Materials intended for aircraft interior parts must meet stringent flammability requirements. Radel R-7300 and R-7400 resins meet or exceed all commercial and regulatory requirements for flammability, smoke density, heat release, and toxic gas emissions.

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 Ds
