With the advancement of science and technology, technological products are being updated faster and faster. In order to maintain the market competitiveness of their products, smart product manufacturers are focusing on performance and new functions. We have put a lot of effort into it. For example, electronic communication equipment pays more attention to waterproof requirements. Waterproof and sound-permeable membrane for phones and watches is a good choice.
Generally, many equipment and their applications require a relatively closed sealed environment, which cannot receive external dust, water, and small bacteria. Influence. If it is designed to be particularly closed, under the objective conditions of changes in ambient temperature and latitude, it will cause pressure changes inside the equipment. Usually, this pressure change will produce a corresponding aggregation effect, which will cause damage to the equipment shell and sensitive internal components. The use of ePTFE waterproof and breathable membrane can continuously balance the pressure difference of the equipment, reduce component design costs, and ensure product reliability and reliability.
The waterproof sound-permeable membrane for phones and watches is made of polytetrafluoroethylene as raw material, using special processing technology, and is rolled and A microporous film made by extrusion, biaxial stretching and other methods. This kind of membrane has excellent breathability, corrosion resistance, aging resistance, temperature resistance and other properties. According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, and the porosity can reach 50%–80%.
The waterproof sound-permeable membrane for phones and watches produced by the manufacturer uses imported raw materials and has a full set of advanced production equipment. , has an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe film; it uses imported production testing instruments to test the quality of ptfe film, and has passed SGS testing and certification, as well as ISI testing and certification.
