Yellow Vent Membrane Eptfe ISO534 0.07mm - 0.17mm Ptfe Membrane Hydrophilic

In the end products equipped with waterproof microphones or receivers and other electroacoustic devices, due to heat, vibration and other reasons caused by pressure accumulation on the microphone or receiver and other electroacoustic devices, resulting in distortion or attenuation of the input or output sound quality or timble. At this point, the waterproof breathable film selected for the requirements should have good sound transmission function and pressure balancing performance, so the waterproof breathable film raw materials that meet the requirements can be used and certain design schemes can be adopted to solve this problem.
Modern society and technology are developing rapidly, with each passing day, with the continuous improvement of people's requirements for the equipment used, many equipment has the requirements of waterproof and dustproof, waterproof breathable film appears in line with the trend, the appearance of waterproof breathable film provides a very good convenience for our life. Waterproof breathable film is a new type of polymer waterproof material, which can reduce the electronic and inductance product failures caused by salt corrosion to a certain extent. Waterproof breathable film can balance the internal and external pressure, thereby reducing the stress of the casing sealing strip and improving the sealing performance of the product.
When the water vapor condenses into water beads, the particles become larger, due to the effect of the surface tension of the water beads (water molecules "pull against each other"), the water molecules can not be smoothly separated from the water beads to penetrate into the other side of the waterproof breathable film, that is, to prevent the penetration of water, with the waterproof function. The waterproof breathable film itself is a material with hundreds of millions of nanoscale micropores, so it has good breathability while waterproof.

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.

• High temperature resistance - working temperature up to 250℃.
• Low temperature resistance - working temperature up to -180C.
• Weather resistance - with the best aging life in plastics.
• High lubrication - is the lowest friction coefficient in solid materials Non-adhesion - is the smallest surface tension in solid materials, does not adhere to any known solid substances.
• Corrosion resistance - inert to most chemicals and solvents, resistant to strong acids and alkalis, water and various organic solvents.
• Non-toxic - has physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reactions.
