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.
