Hydrophobic PTFE Membrane has good hydrophobility, excellent chemical resistance,
high porosity, excellent air permeability. The membrane is widely used for Air Monitoring and clarifying acids, bases, and solvents, propellants, analyzing hydraulic fluids, isolating RNA and so on.
Hydrophilic PTFE membrane is treated base on Hydrophobic PTFE membrane. It’s design as a Universal membrane for filtering both aqueous solutions and aggressive solvents, even mixture.
