Radel® R-7400

Polyphenylsulfone

Solvay SpecialtyPolymers

产品说明：

Radel® R-7300 (for lightcolors) and R-7400 (for darker colors) polyphenylsulfone resinswere developed specifically for aircraft interior applications, andthrough the use of a proprietary flame retardant package, offer lowheat release, low smoke generation, and low toxic gas emissions.These resins comply with the FAA regulation 14CFR Part 25.853Appendix F. In addition, they have excellent impact resistance andESCR when exposed to fluids typically used by the aerospaceindustry, reducing the need for annealing or protectivefilms.

Radel® R-7300 and R-7400 resinshave excellent flow characteristics, readily filling complex partswith thin walls or long flow lengths.

Chemical Resistance:

One of the outstandingcharacteristics of Radel® R-7300 and R-7400 resins is theirresistance to many commonly used aviation fluids. Three testmethods: unstressed immersion, stressed with a 5-inch radius curve,and stressed with a variable radius curve fixture, were employed toevaluate resistance of Radel® resins to Skydrol® LD-4;1,1,1-trichloroethane; Jet fuel A; methyl ethyl ketone; toluene;isopropanol; and Skydrol® 500B.
