Teflon waterproof and breathable membrane is a new material for high-quality masks. The material is a microporous film formed by expanding and stretching polytetrafluoroethylene resin. The average pore size can reach nanometer level.
Since the outbreak of the new crown epidemic, the demand for masks has surged, causing the supply of filter material polypropylene (PP) melt-blown cloth to exceed demand and the price to skyrocket.
Because the expanded polytetrafluoroethylene (PTFE) microporous membrane has a special fibrous microporous structure, when the micropore size is properly controlled, it can physically block viruses and PM2.5 haze particles.
To this end, some companies have combined PTFE microporous membrane with polypropylene non-woven fabrics and other materials to produce PTFE microporous membrane composite filter materials (hereinafter referred to as PTFE mask membrane) to replace melt-blown cloth for use in masks.
The Teflon waterproof and breathable membrane has a small pore size and mainly intercepts pollutants through physical action. There is no need to worry about reduced efficiency when encountering liquids.
After soaking the membrane material in water and 75% alcohol for many times, the filtration efficiency was not affected and remained above 99%. This shows that the membrane material mask can be washed with water or reused after disinfection with alcohol, which greatly increases the number of masks. utilization rate.
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, Teflon waterproof and breathable membranes, 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.
