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
