As the number of epidemics continues to grow and its scope continues to spread, everyone’s awareness of wearing masks has also greatly increased. Mask products in major domestic convenience stores, pharmacies and other retail channels have been sold out.
Due to the spread of the novel coronavirus pneumonia epidemic, masks have become a scarce commodity.
This has also made its important raw material-mask membrane filter material the focus of the industry.
The mask membrane filter material 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.
? It has a complete set of domestic advanced production equipment and adopts advanced production technology. Its products have passed ISO9001 quality management system certification. The testing standards strictly follow the EU standard EN1822. Membrane products are tested using the MPPS method.
