SOLVAY Udel® PSU 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

Udel® PSU excels in many fluid-handling applications in healthcare and plumbing, and has successfully replaced brass in pressurized hot water applications for over 20 years. It exhibits low creep under a sustained load at elevated temperatures and can withstand continuous exposure to hot chlorinated water. 

Its superior thermal, mechanical, and chemical resistance properties compared to more conventional resins, make Udel® PSU the best solution in many more applications such as electrical & electronics (dairy equipment).
