The diameter of water molecules is 0.0004 microns, the smallest diameter mist in rainwater is 20 microns, and the diameter of drizzle is as high as 400 microns. If you can create a film with a pore diameter between water vapor and rainwater, it can be achieved Waterproof and breathable.
PTFE waterproof and breathable membrane can perfectly meet the above conditions.
The working principle of breathability can be divided into two types: micropores and hydrophilic groups. The ptfe waterproof breathable membrane uses the former. Since the minimum diameter of water droplets is about 20 microns, the diameter of water vapor molecules is only about 0.0004 microns. , there is a huge difference in diameter between the two. Water vapor can pass through the microporous membrane through the principle of diffusion. Liquid water or water droplets prevent water molecules from passing through due to their surface tension, which prevents water penetration and makes the breathable membrane more effective. Waterproof function.
A company specializing in the research, development and production of PTFE film products. The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
The ptfe waterproof and breathable membrane produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. It can filter some very small particles with a diameter of 0.1um-0.3um. The level can reach H13-U15.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
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.
