FIBER-BASED MEMBRANES

______________
Ultra-hydrophobic membranes for "macro-venting" applications requiring high air flow and dust protection
Slider
Fiber-Based Membrane

Fiber-based membranes have been surface modified with a super-hydrophobic coating. This coating makes the membrane repellant to water and other liquids while still allowing maximum airflow.  These membranes are used primarily in venting applications and perform well in exterior lighting applications for de-fogging such as automotive lighting.  Fiber-based membranes are easily weldable in highly automated processes for a very cost-effective solution.

Key benefits

  • 100% Free of PFOA: Compliant with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP
  • “Macro-venting” high airflow permeability
  • Best de-fogging performance for exterior lighting solutions
  • Excellent welding characteristics for automized and cost-effective processing
