Hydrophobic PVDF Roll Membrane
Microlab PVDF  membraneis a versatile 100% high temperature resistant polyvinylidene  difluoride membrane. It is designed to provide strength, flexibility and chemical compatibility to meet the rigorous and demanding requirements of chemical filtration applications. Incorporated with no wetting agents, filtration membrane is also an ideal cost-effective alternative to polytetrafluoroethylene membrane to prevent moisture blockage in venting and gas filtration.
Features and Benefits
  • Broad chemical compatibility
  • High throughputs and high flow rates
  • Lowest protein binding
  • Good heat-resistance
