The ptfe coated filter material uses surface filtration instead of “primary dust layer” filtration. The membrane plays the role of a primary dust layer, and the base cloth material only plays the role of supporting the skeleton.
The surface of the film is extremely smooth and the friction coefficient is small. It is difficult to form a thick dust layer on the surface of the film, and there is little dust accumulation on the surface of the film.
And the minimum pore size of the film can reach 0.3um, which can capture most solid particles and liquid droplets.
It has stable chemical properties, high temperature resistance, corrosion resistance, water repellency, oleophobicity, etc.
