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 a tough, rigid and transparent high-strength thermoplastic that is suitable for long-term use up to 300°F (149°C). It is resistant to oxidation and hydrolysis and withstands prolonged exposure to high temperatures and repeated sterilization. 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. Polysulfone is highly resistant to degradation by gamma or electron beam radiation but can be adversely affected by long term exposure to ultraviolet. Electrical properties of the polymer are very stable over a wide range of temperatures and after immersion in water or exposure to high humidity. The resin is very safe for food contact uses. It complies with FDA 21 CFR 177, 1655 and may be used in articles intended for repeated use in contact with foods. Additionally, it is approved by the NSF, by the Department of Agriculture for contact with meat and poultry and the 3-A Sanitary Standards of the Dairy Association. - Transparent: Udel P-3500 NT LCD
