Description:
Radel R-7300 polyphenylsulfone resins were developed specifically for aircraft interior applications, and through the use of a proprietary flame retardant package,offer low heat release, low smoke generation. In addition, they have excellent impact resistance and ESCR when exposed to fluids typically used by the aerospace industry, reducing the need for annealing or protective films. Radel R-7300 resins can be fabricated using conventional injection molding equipment. These materials have excellent flow characteristics, readily filling complex parts with thin walls or long flow lengths.

Radel R-7400 polyphenylsulfone resins were developed specifically for aircraft interior applications, and through the use of a proprietary flame retardant package,offer low heat release, low smoke generation. These resins comply with the FAA regulation 14CFR Part 25.853 Appendix F. In addition, they have excellent impact resistance and ESCR when exposed to fluids typically used by the aerospace industry, reducing the need for annealing or protective films.

Radel R-7700 polyphenylsulfone 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,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. - Available in several custom colors.

Overview:
Radel polyphenylsulfone (PPSU) delivers the highest performance of our sulfone polymers, offering better impact resistance and chemical resistance than polysulfone (PSU) and polyetherimide (PEI).

The high heat resistance and excellent hydrolytic stability of Radel PPSU make it an excellent choice for hot water fittings and medical devices requiring repeated steam sterilization.

These resins offer exceptional hydrolytic stability, similar to that of UDEL polysulfone, with improved toughness, higher heat deflection temperature, and better resistance to environmental stress cracking.

Key Features
High HDT of 207°C (405°F)
Superior toughness and impact strength
Exceptional long-term hydrolytic stability
Better chemical resistance than PSU and PEI
Withstands over 1,000 cycles of steam sterilization without any significant loss of properties
Inherently flame retardant
Transparent
Colorable
