Syensqo (Solvay Specialty Polymers) Udel® P-1750 MR Polysulfone (PSU)  (discontinued **)
Categories: Polymer; Thermoplastic; Polysulfone (PSU)
Material Notes: Udel® P-1750 MR is a lower color grade of polysulfone that contains a mold release which aids part ejection when parts with low draft are injection molded.

Polysulfones have long been known for transparency and clarity, but have been somewhat limited by a slight yellow cast which has been typical of the material. These grades were designed to eliminate the yellow cast and provide improved aesthetics for applications where a yellow cast is undesirable.

Features: Acid Resistant; Alcohol Resistant; Alkali Resistant; Good Chemical Resistance; Good Toughness; High Heat Resistance; Hydrocarbon Resistant; Hydrolytically Stable

Uses: Appliance Components; Appliances; Automotive Electronics; Batteries; Business Equipment; Electrical Parts; Electrical/Electronic Applications; Food Service Applications; Industrial Parts; Microwave Cookware; Piping; Plumbing Parts; Valves/Valve Parts
