Ultrason® PSU & PESU for Membrane (Filtration) Applications
Ultrason® PSU is offered in various molecular weights as granules. Ultrason® E PESU is offered in powder or flakes in a various molecular weights for faster solubility. Ultrason is naturally transparent, and has a high use temperature capability (160° C - 220° C), with excellent chemical and hydrolytic resistance. The scope of advanced, cost efficient membrane applications are constantly expanding. These applications include: water purification, biomedical, manufacturing process separations, waste treatment and food processing.
 Key Features of Ultrason That Make it Ideal are:
• Good pore size• Soluble in solvents commonly used for membrane production • Repeated sterilization possible with superheated steam • Compliance with FDA and European standards for food contact • Can be used over a wide pH range (0 to 13) • Excellent chemical resistance Typical Applications:
• Potable water• Beverage processing • Healthcare • Industrial separations • Semi-conductors Configurations in Modules
• Flat sheet (e.g. used in spiral wound or plate and frame modules)• Hollow fiber (bundles) • Coated tubes BASF Advantage
