Specific Application:
Widely used in microphone, speaker, buzzer, earphone ,smart-watch and so onportable products.
Benefits:
1.The high air permeability vent can reduce the pressure ofthe casing seal by balancing the pressure. This E-PTFEmembrane is chemically inert and,UV-resistant, salt and spray resistance as well as hydrophobic and oleophobic.
2. It greatly reduces fog and condensation.
3. Protective vent can prolong the service life and ensure theproduct operate trouble-free and maintenance-free in the extreme environments.
