Radel® polyphenylsulfone is an amorphous thermoplastic material that offers exceptional hydrolytic stability, and toughness superior to other commercially available, high-temperature films.

PPSU films have high deflection temperatures and outstanding resistance to environmental stress cracking. The polymer is inherently flame retardant. The excellent thermal stability makes films suitable for applications where very low shrink at high temperatures are needed. PPSU films also have good electrical properties.

Radel® film is off-white in color.

Applications: Aerospace Applications; Aircraft Applications; Automotive Applications; Batteries; Electrical/Electronic Applications; Food Service Applications; Medical/Healthcare Applications

Features: Flame Retardant; Good Electrical Properties; Good Thermal Stability; Good Toughness; High ESCR (Stress Crack Resist.); Hydrolytically Stable
