The new coronavirus is approaching fiercely, affecting the nerves of the whole society. At the moment when the whole people are mobilizing to prevent and control the epidemic, we all know that going out less, wearing masks, and not gathering are the most effective protective measures, and disposable medical mask filter materials It has also become one of the most important supplies at the moment.
The conventional production process is to mix polytetrafluoroethylene dispersion resin with liquid additives, make the mixture into thin sheets by calendering, and then use a machine to bidirectionally stretch the thin sheets to produce a PTFE microporous membrane.
The process flow is: PTFE resin, extrusion aid (material selection) – mixing – calendaring, bidirectional stretching – coiling.
The filter material of disposable medical masks can filter more than 95% of bacteria and PM2.5 particles in the air, 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 (pore size interception method). 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 more stable and lasting.
Suzhou New Material Technology Co., Ltd. is a fluorine material film manufacturer that integrates the R&D, production and sales of PTFE air filtration membranes, PTFE bubble point membranes, disposable medical mask filter materials, Teflon films and coated filter materials.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
The company can provide samples and arrange sales staff to provide door-to-door service if there are other requirements.
You are welcome to come to the company for inspection or enter the store to consult us at any time.
