The mask uses PTFE microporous membrane composite polypropylene (PP) non-woven fabric as the core filter layer to replace polypropylene melt blown filter layer. The weight of the composite is 25-27 g / m2. The PTFE composite non-woven fabric has very high bacterial filtration efficiency under the condition of ensuring the inspiratory and expiratory resistance requirements in relevant standards. Long term effective filtration efficiency. Compared with the general use of "electrostatic electret" melt blown mask, PTFE composite non-woven mask has long-term stable filtration efficiency, and its filtration performance will not fluctuate greatly with the passage of time or the change of external environment (humidity, high and low temperature, sterilization process). It is an ideal material for mask filter element. Excellent wearing comfort (dry).
Polytetrafluoroethylene is a natural hydrophobic material. When people wear masks with polytetrafluoroethylene composite non-woven fabric as the core filter layer, the "wet saturated gas" exhaled by the human body passes through the core filter layer very smoothly, and the moisture is rarely intercepted in the filter layer. The inside of the mask will not feel wet when worn for a long time.
