What is the application of Teflon breathable membrane in the electronic field?

Teflon breathable membrane is a microporous membrane made of a polymer compound polymerized from tetrafluoroethylene using special processes such as calendering, extrusion, and biaxial stretching.

It can effectively intercept dust particles in the air, and the material has strong hydrophobicity, non-adhesion, corrosion resistance, thermal stability and good mechanical properties.

Electronic equipment is often exposed to dust or liquid splashes.

Mobile phones and other portable wireless devices are generally used in harsh environments and may come into contact with water and dust, which can damage sensitive components.

Teflon breathable membrane products can prevent dust, dirt or liquid from intruding into precision instruments such as electronic equipment.

At the same time, gas can be allowed to pass through the film immediately, thereby ensuring that the response speed of electronic equipment remains constant. The PTFE breathable film produced by our company has a film porosity of more than 85%, allowing air to circulate smoothly.

The membrane pore size is 0.1-1μm, which can effectively block water droplets, and the waterproof level can reach IPX7 or above.
