PTFE Membrane Filters

PTFE (Teflon) membranes are available in hydrophilic, hydrophobic, oleophobic, supported, and unsupported options for a wide range of applications involving strong/aggressive acids, bases, and solvents incompatible with most other filtration media.

The laminated membranes are thicker and chemically and biologically inert, stable up to 260°C (500°F) and naturally hydrophobic; they are used for aerosol sampling, air venting, and gas filtration. A full line of hydrophilic PTFE membrane filters are offered for filtering aqueous solutions.

PTFE Membranes Selection

PTFE Laminated Membrane Filters
These hydrophobic PTFE membrane filters made of pure ePTFE laminated onto a polypropylene, PET non-woven layer, providing strength and high chemical compatibility for aggressive solvent filtration, phase separations, venting, and aerosol sampling.

PTFE Unlaminated Membrane Filters
Unsupported hydrophobic PTFE membrane filters are ideal for sterilization and venting applications involving air, gasses, and solvents/acids incompatible with most other filters.

Oleophobic Laminated PTFE Membrane Filters
oleophobic membranes are ideally suited for applications where liquid contain oil.

Hydrophobic Application

  • Environmental air filtration and analysis
  • Organic solvent filtration
  • Pharmaceutical industry
  • Semiconductor industry

Hydrophilic Application
