Children’s smart phone watches have been used as children’s wearable products in recent years to protect children’s safety and build a bridge of communication between parents and children. It is very popular among children and parents. Do you know what materials are needed to produce this product? The waterproof sound-permeable membrane for phones and watches is one of them.
The real waterproof and breathable membrane is not compounded with glue, so its temperature resistance is -40,100 degrees (EU CE standard, US ASTM standard). It is not produced with polyethylene or TPO coating, so the air permeability should exceed 1500g/square/24 hours. If it is produced with polyethylene or TPO coating, it is basically not breathable. Hydrostatic pressure testing shows that the hydrostatic pressure of a thin waterproof and breathable membrane is at least 1.5 meters, and that of a thick waterproof and breathable membrane is at least 2 meters.
The waterproof and sound-permeable membrane of the phone and watch is a purely physical barrier and does not rely on static electricity. When the user inhales, the pore size of 100~200 nanometers will pass through the physical screening of PM2.5 to PM0.3. Blocked on the surface of the mask, with the help of the super self-lubricating characteristics of the polytetrafluoroethylene material, every time you exhale, the particles attached to the surface of the mask will be pushed back into the environment. This repeats without relying on electrostatic adsorption. It truly achieves effective PM2.5 protection effect.
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.
