Radel® R polyphenylsulfone offers many of the same performance features as Udel polysulfone along with higher resistance to fatigue, better long-term exposure to hydrostatic stress, extremely high impact strength, and exceptional chemical resistance.

Key Features

• Exceptional toughness and impact resistance
• Best  chemical resistance among high temperature amorphous thermoplastics
• Outstanding long term hydrostatic strength
• Extremely low creep

Applications

• Hot water fittings and manifolds
• Sterilizable surgical trays and containers
• Aircraft cabin interior components
• Membranes (fuel cells, gas separation …)

Radel R polyphenylsulfone provides and extra margin of toughness and chemical resistance to demanding applications. Among the amorphous high temperature thermoplastics Radel R PPSU has outstanding chemical resistance and long term hydrostatic strength. Four colors are offered for plumbing applications.
