In today’s era, with the development of industry and the improvement of people’s living standards, the demand for waterproof and breathable clothing fabrics is increasing year by year. Researchers from various countries have begun to focus on the research of PTFE nano mask filters and coating products.
The stretching process of ptfe is a process in which fine fibers are continuously pulled out from the folded lamellae and become longer and thinner.
During the unidirectional stretching (longitudinal stretching) process of the PTFE calendered film, the fine fibers are continuously pulled out, forming island-shaped nodes composed of unstretched crystal regions and slender connecting nodes. The node composed of two fibers – fiber structure.
The filtration efficiency of ptfe nano mask filter membrane for bacteria and PM2.5 particles in the air can reach more than 95%, reaching the filtration standard of KN95 masks.
The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing.
In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception. The interception rate will not be attenuated due to moisture in the exhaled breath. Compared with ordinary melt-blown cloth masks, the protective effect of electrostatic adsorption is better More stable and durable.
Suzhou New Material Technology Co., Ltd. is a fluorine material membrane that integrates the research, development, production and sales of ptfe air filtration membranes, ptfe bubble point membranes, ptfe nano mask filters, Teflon membranes and coated filter materials. factory.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
The company’s products are widely used in various fields. The company has always implemented the purpose of “quality first, reputation first” to provide users with high-tech, high-quality, high-performance, and high-level products.
