Syensqo (Solvay Specialty Polymers) Udel® P-3703 PSU, Transparent
Categories: Polymer; Thermoplastic; Polysulfone (PSU)

Material Notes: Transparent, high flow for injection molding

Udel® P-3703 is a high-flow grade of polysulfone intended for injection molding applications with thin walls or long flow lengths. This grade has higher flow than Udel® P-1700 and a slightly greater tendency to stress crack in some aggressive environments.

Udel® polysulfone is a tough, rigid, high-strength thermoplastic that maintains its properties at temperatures from -101°C to 149°C (-150°F to 300°F). The heat deflection temperature at 1.8 MPa (264 psi) is 174°C (345°F). For most purposes, this resin is suitable for continuous use up to 149°C (300°F). The material is resistant to oxidation and hydrolysis and withstands prolonged exposure to high temperatures and repeated sterilization. Udel polysulfone is highly resistant to mineral acids, alkali and salt solutions. The resistance to detergents and hydrocarbon oils is good, but it will be attacked by polar solvents such as ketones, chlorinated hydrocarbons and aromatic hydrocarbons.

Electrical properties of Udel polysulfone are stable over a wide temperature range and after immersion in water or exposure to high humidity.

- Natural: Udel® P-3703 NT 11

Applications: 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

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