In today’s society, it is very common to equip children or the elderly with some electronic products, such as Smartphones, smart phone watches, etc. Did you know that in order to better adapt to various environments, these high-tech devices need to use materials such as waterproof and sound-permeable membranes for phones and watches?
The technology of waterproof and breathable membranes was first introduced from European and American countries. However, the production processes of domestic products are diverse, and the quality of products from various manufacturers is uneven, and a unified quality standard has not been formed. In fact, waterproof and breathable membranes mainly consist of three layers: PP spunbond non-woven fabric, PE polymer breathable membrane, and PP spunbond non-woven fabric. The main function of spunbond non-woven fabric is to enhance the tensile force and hydrostatic pressure and protect the middle layer (breathable film). The real breathability mainly depends on the middle layer PE polymer breathable film.
The waterproof sound-permeable membrane for phones and watches 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.
It is a manufacturer of waterproof and sound-permeable membranes for phones and watches that integrates production, sales and customization. The company has advanced PTFE film production lines and composite production lines. The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
