The polytetrafluoroethylene mask film is generally made of polytetrafluoroethylene (ptfe) suspended powder, which is expanded and stretched to form a microporous film.
Bubble point film has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is coated on various fabrics using a special process and base material, it can become a new type of filter material.
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.
? is a fluorine material film manufacturer integrating production, sales and customization.
Our company is different from other manufacturers. Our company can produce products according to user requirements.
The key to the technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. According to the ratio and pore-forming medium, the air permeability, thickness and void ratio can be adjusted online to meet your different requirements. .
