Description

Membrane Solutions offers an inherently hydrophobic expanded polytetrafluoroethylene (ePTFE) membrane with a polypropylene (PP) or polyester (PET) support layer. Our unique process creates a product with high peel strength, stable and uniform mechanical properties, making it easy to cut, and can be welded or sealed into a device or patch. MS® hydrophobic PTFE Venting membranes are optimized for venting applications where high air/gas flow rates and high water entry pressure are required.

Features

  • High water entry pressure

  • Excellent air/gas permeability

  • Uniform

  • Strong mechanical properties

  • Broad chemical resistance and high temperature stability

Applications

  • Inline gas or air filtration devices

  • Venting devices

  • Package or enclosure venting

  • Dust collectors and baghouse filters

  • Coalescing

  • Hydrophobic barriers
