DESCRIPTION

Transparent Plastic With High Strength & Rigidity

Udel® PSU (polysulfone) is a rigid, high-strength, semi-tough, transparent plastic that offers higher heat resistance and better hydrolytic stability than polycarbonate. It retains its good mechanical properties when exposed to steam and other sterilization techniques.

Udel® PSU polymers are particularly well suited for the fabrication of porous hollow fiber and flat sheet membranes using a solvent-based process. These high molecular weight polymers are used in a variety of membrane filtration applications, such as renal dialysis, water treatment, bio-processing, food and beverage processing, and industrial gas separation.

Why Udel® PSU?

*Excellent thermal stability
*Well suited for the fabrication of hollow fiber and flat sheet membranes
*Stability at pH levels from 2-13
*Excellent resistance to caustic and good resistance to chlorine
*Low levels of extractible and insoluble materials
*May be sterilized using steam, ethylene oxide, and e-beam radiation
*High toughness and strength
*Good environmental stress cracking resistance
*High heat deflection temperature, 174°C (345°F)
*Combustion resistance
*Transparency
*Approved for food contact and potable water
*Low creep

The Udel P-3500 LCD is an extremely high molecular weight polysulfone with the highest toughness and chemical resistance among the available brands.Very suitable for extrusion. The advantage of the Udel P-3500 LCD stems from its lower levels of a circular dimeric polymer. Polysulfone is a high-toughness, high-rigidity, and transparent, high-strength thermoplastic suitable for long-term use at temperatures up to 300 ° F (149 ° C). Antioxidant, antihydrolysis, can be exposed to high temperature environment for a long time, and can be repeated sterilization.
