Mobile phones have become an essential tool in people’s lives. Since the mobile phone receiver accessories are not waterproof, the mobile phones may be damaged due to contact with moisture in some special environments. In order to effectively solve this problem, the mobile phone receiver waterproof and sound-permeable membrane It came into being.
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 fabrics is to enhance tensile force and hydrostatic pressure and protect the middle layer (breathable film). Real breathability mainly relies on the middle layer PE polymer breathable film.
The waterproof and sound-permeable membrane of the mobile phone handset is a purely physical barrier and does not rely on static electricity. When the user inhales, the pore size of 100~200 nanometers will physically filter PM2.5 to PM0.3 and block it on the surface of the mask. , with the help of the super self-lubricating characteristics of polytetrafluoroethylene material, every time you exhale, the particles attached to the surface of the mask will be pushed back into the environment. Repeatedly, without relying on electrostatic adsorption, it is truly effective. PM2.5 protective effect.
It is a manufacturer of waterproof and sound-permeable membranes for mobile phone handsets 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.
