OVERVIEW of Radel® R-7400 PPSU Resin

Radel® R-7400 and R-7300 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.

These resins offer exceptional hydrolytic stability, similar to that of UDEL® polysulfone, with improved toughness, higher heat deflection temperature, and better resistance to environmental stress cracking.

Radel R-7300 and R-7400 resins can be fabricated using conventional injection molding equipment. These materials have excellent flow characteristics, readily filling complex parts with thin walls or long flow lengths.

While the two resins exhibit nearly identical performance characteristics, Radel R-7300 is formulated for applications requiring light colors and R-7400 is preferred for applications specifying darker colors.

Chemical Resistance:
One of the outstanding characteristics of both Radel R-7300 and R-7400 resins is 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. In all cases, Radel R-7000A resin exceeded industry requirements and was clearly superior to the competitive materials. Radel R-7300 and R-7400 resins, while providing improved processing and physical properties, have the same base resin composition as R-7000A resin and will yield similar chemical resistance results.

Typical Applications of Radel® R-7400 PPSU:

Passenger service units - Window reveals and shades - Video shrouds - Flight deck components - Air vents and return grilles - Galley carts and boxes
