For most parents, the safety of their children is always a concern, but with the With the rapid development of technology, various smart wearable devices have begun to pop up like mushrooms after a rain. For example, children’s smart phone watches have become the first choice of many parents. What we are going to talk about today is the waterproof sound-permeable membrane for phones and watches.
The waterproof and breathable membrane is known as/commonly known as the “King of Plastics”, and the Chinese product names are “Teflon”, “Teflon” (teflon), “Teflon”, “Teflon”, “Taiwan” Fluoron” etc. It is a polymer compound made of tetrafluoroethylene and has excellent chemical stability and corrosion resistance (it is one of the best corrosion-resistant materials in the world today). An important way to solve waterproofing is to lay anti-breathable membrane.
The waterproof sound-permeable membrane for phones and watches is made of polytetrafluoroethylene material through special processes such as mixing, extrusion, extrusion, calendering, and bidirectional stretching. The porosity of the membrane can reach more than 88% or even higher, and the membrane has 1.4 billion micropores per square centimeter, with a pore diameter ranging from 0.1um to 0.5um. The high-efficiency filter paper 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 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.
