Radel® R-7400 Solvay Specialty Polyphenylsulfone

Product Description

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.
