Fiber-based membranes have been surface-modified with a super-hydrophobic coating to repel water and other liquids while still maintaining maximum airflow. These membranes are used primarily in venting and perform well in exterior lighting applications – such as those in automotive markets – for de-fogging purposes. Fiber-based membranes are easily weldable via a highly automated process that serves as a very cost-effective solution.
- 100% Free of PFOA: Compliant with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP
- Ideal for “Macro-venting” applications – high airflow permeability and dust protection
- Best de-fogging performance for exterior lighting solutions
- Excellent welding characteristics for automized and cost-effective processing
