Product Description
Radel® R-7159 polyphenylsulfone (PPSU) was developed specifically for aircraft interior applications. The product complies with the FAA regulation 14CFR Part 25 Appendix F, offering vertical burn resistance, very low smoke generation and, through the use of proprietary additives, low heat release values in the Ohio State University (OSU) rate of heat release method. It also generates low flaming-mode toxic gas emissions.

The material offers good resistance to most fluids found in the aviation industry. It is available in pigmented grades to match OEM color standards and in a natural-color grade that is designed to accept aircraft paint systems for aesthetic parts. Painting enhances the chemical resistance of the polymer and provides the final step in color coordination.
