Nowadays, there are many types of masks on the market, but generally they can be roughly divided into industrial masks, medical masks, civilian masks (that is, daily protective masks), and professional anti-haze masks.
Most of these masks use polytetrafluoroethylene mask film.
Dust masks are essential protective equipment for workers who are engaged in and exposed to dust.
Mainly used in operating environments containing low concentrations of harmful gases and vapors and operating environments that generate dust.
The poison filter box contains only adsorbent or sorbent.
Some poison filter boxes are also equipped with a filter layer, which can prevent aerosols at the same time.
Some military gas masks are mainly made of activated carbon cloth, or water-resistant and oil-resistant fabric as the outer layer, glass fiber filter material as the inner layer, and activated carbon-impregnated polyurethane foam as the bottom layer. They can be used when suddenly attacked by poisonous gas. Provide temporary protection.
The polytetrafluoroethylene mask film is a microporous film made by calendering, extrusion, biaxial stretching and other methods using a special processing technology.
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 is a manufacturer of polytetrafluoroethylene mask membranes that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
