Solvay Specialty Polymers Radel® R-7159 Polyphenylsulfone (PPSU)

Technical Datasheet | Supplied by Solvay
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. This resin offers good resistance to most fluids found in the aviation industry and is available in a natural color that is designed to accept aircraft paint systems for aesthetic parts. The painting function enhances the chemical resistance of the polymer and provides the final step in color coordination. - Natural: Radel R-7159 NT 50
