Mobile phones have become an essential tool in people’s lives. Since the handset accessories of mobile phones are not waterproof, Mobile phones are damaged due to contact with moisture in some special environments. In order to effectively solve this problem, PTFE waterproof and sound-permeable membranes came into being.
If the building wall does not use a waterproof and breathable membrane, when condensation occurs due to the temperature difference between hot and cold, water droplets will form on the roof or wall surface, and the water droplets will invade the building or insulation layer and reduce the insulation layer. thermal efficiency, and affects the durability of the building. After the waterproof and breathable membrane is installed, water vapor can be smoothly discharged through the waterproof and breathable membrane. When water vapor condenses into water droplets on the inside of the roof tile, it drops directly on the waterproof and breathable membrane and flows out smoothly from the drainage channel.
PTFE waterproof sound-permeable membrane is a microporous membrane made by calendering, extrusion, and biaxial stretching. The porosity can reach more than 85%, and the air can flow smoothly. The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above. Protect electronic instruments from becoming unusable due to moisture or water. Compared with other breathable filter materials, it has excellent air permeability. It is difficult to form a thick dust layer on the surface of the film, and the dust can be naturally peeled off.
The PTFE waterproof sound-permeable membrane produced by the manufacturer uses imported raw materials, has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring the quality of the PTFE membrane. Production quality; using production and testing instruments imported from the United States to test the quality of PTFE film, it has also passed international SGS testing and certification, and ISI testing and certification.
