People discover a better life and become their best companions on this journey.
Expanded polytetrafluoroethylene membrane, referred to as ePTFE membrane, is a new type of polymer material with a micron or sub-micron porous three-dimensional network microstructure. It is made of PTFE resin through special processing methods such as stretching and turning. , while maintaining the excellent chemical properties of PTFE, by changing the structure, shape, thickness, surface geometry of the material, and then matching it with auxiliary materials with different characteristics, different functions and uses can be achieved.
PTFE electronic membrane manufacturer Teflon waterproof and breathable membrane uses the former. Since the minimum diameter of water droplets is about 20 microns, while the diameter of water vapor molecules is only about 0.0004 microns, there is a huge difference between the diameters of the two. Steam can pass through the microporous membrane through the principle of diffusion. The surface tension of liquid water or water droplets prevents water molecules from passing through, thus preventing water penetration and making the breathable membrane waterproof.
It is a ptfe electronic film manufacturer integrating 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.
