Solvay Specialty Polymers Udel® P-3500 LCD Polysulfone (PSU)

Udel® P-3500 LCD is a very high molecular weight grade of polysulfone, and therefore offers the greatest toughness and chemical resistance of the available grades. It is well-suited for extrusion. The advantages of Udel® P-3500 LCD are attributed to the lower level of cyclic dimer present in the polymer. Polysulfone is resistant to mineral acids, alkali, salt solutions, detergents and hydrocarbon oils. Contact with polar solvents such as ketones, chlorinated hydrocarbons and aromatic hydrocarbons should be avoided, as these types of chemical compounds can cause stress cracking or solvate polysulfone resin.Features: Acid Resistant; Alcohol Resistant; Alkali Resistant; Detergent Resistant; Good Chemical Resistance; Good Dimensional Stability; Good Sterilizability; Good Surface Finish; Good Toughness; High Heat Resistance; Hydrocarbon Resistant; Hydrolytically Stable; Steam SterilizableUses: MembranesInjection Molding Notes: UDEL P-3500 polysulfones may be dried before preparing solutions. Pellets can be dried in a circulating hot air oven, by spreading the pellets on trays to a 1-2 inch depth and drying for 3.5 hours at 257 to 325°F (135 to 163°C).Information provided by Solvay Specialty Polymers.
