Product Description
Radel® R-7700 polyphenylsulfone sheet was developed specifically for aircraft interior applications. Through the use of a proprietary flame retardant package, this resin offers low heat release, low smoke generation and low toxic gas emissions, thereby complying with the FAA regulation 14CFR Part 25.853 Appendix F. In addition, it has excellent impact resistance and meets typical industry requirements for resistance to aerospace fluids, even under stress.

Radel® R-7700 is available in pellets and sheet form.

Radel® R-7700 sheet can be formed into large complex geometries with relative ease on conventional thermoforming equipment. Please reference the Technical Bulletin Thermoforming Radel® R-7700 Sheet for additional information.

Additional Information
The Federal Aviation Admininstration (FAA) has issued stringent regulations covering materials for use in commercial aircraft interiors. As shown in the Heat Release and Smoke Density data above, Radel R-7700 sheet complies with these regulations.

In addition, several airframe manufacturers have an additional requirement that, when these materials burn, any smoke generated contain no more than defined levels of specific toxic gases. Radel R-7700 polyphenylsulfone sheet typically exhibits levels of these gases that are much lower than the maximum levels allowed, see Toxic Gas Emission data above.
Features
Features may also be described by the following terms: Low Smoke Emission, Detergent Resistant, Detergent Resistance, Low Toxicity, Good Processing Stability, Good Process Stability, Good Toughness, Tough.
Agency Ratings
This plastic material has 3 certifications from the following agencies (the number in parentheses shows the number of certifications for that agency): AAMA (1), FAA (1), OSU (1).
