As mobile phones, tablets, and other acoustic devices fill our lives, we hope they will not only It can only work with good performance in clean and orderly living and working places, and can also work in various other environments. This requires the use of 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, failing to form a unified quality standard. 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 porosity of the waterproof and sound-permeable membrane for phones and watches can reach more than 88%, or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore diameter ranging from 0.1um to 0.5um, and high-efficiency filter paper It has high and low temperature resistance (-200℃ – 260℃). It will not age, split or discolor after long-term use, and has strong weather resistance.
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. Moreover, we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
