Hemodialysis Membranes 

 
Expand All Collapse All
Overview

Udel® polysulfone (PSU) is used around the world to make dialysis membranes, which serve as artificial kidneys for a growing number of our population. Polysulfone has become the polymer of choice for this life-saving application and offers several advantages over cellulose acetate.

  • Easy to form fine hollow fiber membranes
  • Dope solution stability
  • Excellent biocompatibility
  • Sterilizeable by steam, ethylene oxide and e-beam radiation

Udel P-3500 LCD MB is a tough high-strength grade that's well-suited for dialysis membranes. Its low level of cyclic dimer can improve the stability and shelf life of dope solutions. A range of narrow molecular weights with controlled viscosities makes it easier to fine-tune dope solutions and optimize your membrane manufacturing process.

Veradel® polyethersulfone (PESU) offers many of the same features as Udel polysulfone with the added benefit of high heat resistance.

Specialty polysulfone grades are also available for manufacturers using PVP (polyvinylpyrrolidone).
