Polytetrafluoroethylene ptfe microporous film is a microporous film formed by stretching polytetrafluoroethylene resin particles at temperatures below the melting point and hot spot shaping. It is a flexible and elastic microporous film. The material has uniform pore size distribution and is breathable and impermeable.
The ptfe reusable mask filter membrane adopts a special processing technology and is a microporous film made by calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
Three-dimensional mesh structure, no through holes.
The porosity and pore size distribution are important indicators for measuring films.
The porosity of the film is generally between 80% and 95%. A high porosity will increase the ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
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, PTFE reusable mask filters, Teflon membranes and coated filter materials.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
