Hydrophilic PES Membrane for Clarification and Particulate Removal



Hydrophilic PES membrane consists of pure polyether sulfone 
polymers without support. It is featured by good mechanical strength, thermal stability and broad chemical compatibility. It’s applicable for pure water filtration, protein solution filtration, medium filtration, buffer filtration, etc.

Features and Benefits

  • Good chemical compatibility
  • Wide range of removal ratings
  • Low bio-adsorption
  • Asymmetric structure, high flow rates
