kn95 mask filter membrane is a new type of filter material. It is also an indispensable and important material for making kn95 masks. This material can play a good blocking role and has excellent filtration effect. It is a very Good mask filter material.
As the prevention and control of the pneumonia epidemic caused by the new coronavirus infection continues to deepen, professional terms such as N95 and KN95 have attracted widespread attention on the Internet, and the standards of masks have entered the public eye.
On January 31, 2020, the National Health Commission issued the “Guidelines for the Protection of Populations at Different Risks of Novel Coronavirus Infection” and mentioned KN95/N95 many times.
The kn95 mask filter membrane adopts a special processing technology and is a microporous film made by calendering, extrusion, and biaxial stretching.
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.
PTFE film manufacturer specializes in the production of kn95 mask filter membranes. It has a full set of advanced production equipment and technology. It also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the product materials produced are all Using imported raw materials, it has high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
