Waterproof sound-permeable membrane for phones and watches is a polymer compound made of polymerized tetrafluoroethylene. It has excellent chemical stability, corrosion resistance and other excellent properties.
In fact, waterproof watches are of course waterproof, but the use scenarios need to be distinguished according to the waterproof level. For example, the relatively common 3ATM (30 meters waterproof) and 5ATM (50 meters waterproof) on the market can meet daily life needs. It is necessary to wear it, but when your use scenarios include car washing, swimming, surfing, and diving, you need a higher waterproof level for protection, so 10ATM (100 meters waterproof) products came into being.
The working principle of breathability can be divided into two types: micropores and hydrophilic groups. Phone and watch waterproof sound-permeable membrane uses the former, because the minimum diameter of water droplets is about 20 Microns, while the diameter of water vapor molecules is only about 0.0004 microns. There is a huge difference between the two diameters. Water vapor can pass through the microporous membrane through the principle of diffusion. Liquid water or water droplets cannot pass through due to the surface tension of liquid water or water droplets. This prevents water penetration and makes the breathable membrane waterproof.
