Today I would like to introduce a new type of material to you, which is the polytetrafluoroethylene mask film produced and developed by the company.
It is a new type of environmentally friendly material. Let’s take a closer look at it.
Polytetrafluoroethylene has a strong application background in traditional industrial fields and is often used as a purification material. One of the reasons is that it is washable and has low moisture absorption.
This attribute allows 98% of the moisture generated by human breathing to be smoothly discharged from the mask when using the mask, achieving an efficient moisture permeability effect.
PTFE nano film mask is an anti-smog mask developed with polytetrafluoroethylene mask membrane as the filter core. The core filter layer of this mask is composed of fiber pores with a nanometer diameter of only 100-200 nanometers. The distribution is very uniform and is much smaller than the diameter of pollutants such as PM2.5.
In addition, the membrane mask adopts the principle of physical filtration, relying on the tiny nanopore size to directly block pollutants. The protective performance is not affected by external forces, so it can always maintain a stable and long-lasting protective effect.
The polytetrafluoroethylene mask membrane is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
