    What is PvDF?

    Johnson Test Papers’ PVDF membrane is a hydrophobic, versatile high temperature resistant polyvinylidene difluoride membrane. It is particularly microporous and highly efficient in particle removal.

    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, PVDF filtration membrane is also an ideal cost-effective alternative to polytetrafluoroethylene (PTFE) membrane to prevent moisture blockage in venting and gas filtration.

    For additional information on OEM specific applications, Johnson Test Papers has the product breadth and flexibility to meet your needs, as well as the quality standards to help ensure your success.

    • Stack consists of reinforced-type PVDF membrane. Possess superior properties of heat-resistance and chemical-resistance
    • Holds the opposite capability against hydrophilic membrane
    • Can ensure wet air and other gas pass through smoothly, even when the differential pressure is very low. But the water liquid cannot permeate
    • High thermal and chemical resistance
    • Resistant against most organic solvents and aggressive liquids
    • Wide chemical compatibility: pH 1 - 14
