  • Colors ranging from bright white to dark blues
  • Grades comply with U.S. Federal Aviation Administration (FAA) flammability regulations

Solvay Specialty Polymers introduced a new series of pre-colored, injection-moldable polyphenylsulfone (PPSU) resins for commercial aircraft interior applications. The new Radel R-7159 colors provide a cost-effective way to match interior color standards established by leading aircraft OEMs, according to the company.

Colors ranging from bright white to dark blues

The company formulated its Radel R-7159 pre-colored grades to match interior color standards for leading aircraft manufacturers, such as Boeing, with colors ranging from bright white to dark blues and grays. The colored grades expand upon the company’s Radel R-7159 NT 50 PPSU, a natural-colored commercial resin for general interior components suitable for painting.

Grades comply with U.S. Federal Aviation Administration (FAA) flammability regulations

The new tightly color-matched resins provide very good impact strength and resistance to commercial cleaners and insecticides. They also comply with U.S. Federal Aviation Administration (FAA) flammability regulations for materials used in aircraft cabin interiors. Specifically, they meet Federal Aviation Regulation (FAR) 25.853, Appendix F, Part 1 requirements for low flammability and heat release, low smoke generation and OEM standards for low toxic gas emissions.

The new pre-colored Radel R-7159 resins are available from both Solvay and RTP Company, who recently signed a licensing agreement allowing it to manufacture and sell select aerospace-grade PPSUs under Solvay’s established Radel brand. The agreement offers greater flexibility to customers who wish to order the pre-colored resins in smaller lot sizes or in custom colors.
