Now the protection requirements and standards for some electronic terminal equipment products are getting higher and higher, and some intelligent electronic devices sometimes have to be used in the outdoor environment with rain and water fog, and even in the water. In order to prevent water and other liquids from entering the interior of the terminal equipment and affecting the work of the electronic equipment, it is necessary to adopt a reasonable design scheme for a good sealing design.

application
This series of membranes could be used in Automotive Lamps, Automotive Sensitive Electronics, Outdoor Lighting, Outdoor Electronic Devices, Household Electrical and Electronics etc.
The membrane can balance inside/outside pressure differentials of sealed enclosures while blocking contaminants, which could increase components’ reliability and extend their service life.

What are the functions of ePTFE as a new waterproof and breathable material?
- Waterproof: 0.1-10μm microhole, the aperture is less than 10,000 times water beads, so that water can not pass through, effectively protect sensitive parts, avoid liquid erosion, improve product life.
- Air permeability: the micropore diameter is 700 times greater than water vapor, waterproof at the same time, allowing air to pass smoothly, can effectively dissipate heat, prevent the inner wall of the product from forming fog, balance the internal and external space pressure.
- Dust-proof: The microporous channel forms a mesh three-dimensional structure in the film, and the uniform and dense distribution of micropores makes the dust encounter a barrier, achieving an effective dust-proof effect, and the minimum can capture 0.1μm particles. Protection level: IP67.
