Radel® R-7625 polyphenylsulfone resin is a cost-effective solution for aircraft interior applications that offers improved UV resistance versus Radel® R-7535 and Radel® R-7558. 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, when tested using the Ohio State University (OSU) rate of heat release method. It also generates low flaming-mode toxic gas emissions.
Radel® R-7625 resin is available in light colors and is formulated for integrally colored applications.
