Microporous film phone watch waterproof sound-permeable membrane
In recent years, the domestic smart phone and watch market has shown a trend of prosperity and development, with huge market prospects. It has also become a battleground for major domestic and foreign smart wearable device manufacturers. Today we will talk about the waterproof and sound-permeable membrane material for phone watches, which is an important component of smart phone watches.
On the surface, there are obvious pressure points on both sides of the waterproof and breathable membrane. That is because the production process is through hot pressing and compounding. Please note that these are not points on the non-woven fabric itself. lines, but very obvious overlapping dots. Tear open the waterproof and breathable film. First, the middle polymer layer should be a milky white and soft waterproof and breathable layer. Because it is compounded by hot pressing, there should be pressure points on this layer of film.
The waterproof sound-permeable membrane for phones and watches is made of polytetrafluoroethylene as raw material, which is expanded into a microporous film, and then the film is laminated on various fabrics or papers using a special process. On the base material, it becomes a new type of material. The material must not only be moisture-wicking, breathable, and comfortable to wear, but also protect medical staff from infection by various contaminants such as viruses and bacteria during diagnosis and treatment, and resist the intrusion of water, alcohol, and blood. It must also be effectively antistatic and even Prevent dust from entering.
It is a high-tech enterprise specializing in the research and development, production and sales of waterproof sound-permeable membranes for phones and watches. It has a factory area of nearly 8,000 square meters and professional production equipment. It is a Fortune 500 company in the United States. Partners; the products we produce are all produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
