Solvay Specialty Polymers Radel® R-7700 Polyphenylsulfone (PPSU), Premium grade resin and deep draw sheet for thermoforming
Categories: Polymer; Thermoplastic; Polyphenylsulfone (PPSU)

Material Notes: Premium grade resin and deep draw sheet for thermoforming, for aircraft interiors

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.

- Available in several custom colors

Markets/Uses: Aircraft / Aircraft Interiors / Extruded Profiles and Tubing; Aircraft / Aircraft Interiors / Flight Deck Components; Aircraft / Aircraft Interiors / Galley Carts and Boxes; Aircraft / Aircraft Interiors / Video Shrouds

Applications: Aerospace Applications; Aircraft Applications; Aircraft Interiors

Features: Detergent Resistant; Flame Retardant; Good Processing Stability; Good Toughness; Low Smoke Emission; Low Toxicity

The Federal Aviation Administration (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.
