Processing technology of ptfe coating processing

Maybe everyone is wondering why many good companies that produce ptfe microporous membranes do not sell membranes directly Or rarely sell films, the reason lies in the laminating technology. Today we will take a look at ptfe laminating processing.

The coated printed matter has a thin and transparent plastic film on the surface, making the surface smoother and brighter. This not only improves the gloss and fastness of the printed matter, but also extends the service life of the printed matter. The plastic film also plays a protective role such as moisture-proof, waterproof, anti-fouling, wear-resistant, folding-resistant, and chemical corrosion-resistant.

PTFE coating processing The coating process of PTFE coated filter material is a surface processing process after printing. It is also called post-printing over-molding and post-printing mounting. Gluing or post-printing lamination refers to using a laminating machine to cover the surface of the printed product with a layer of 0.012-0.020mm thick transparent plastic film to form a paper-plastic product processing technology. Generally speaking, it can be divided into two types: ready-coated film and pre-coated film according to the process used. According to the different film materials, it can be divided into two types: bright film and matte film.

PTFE-coated polytetrafluoroethylene microporous membrane is prepared using a unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux. The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um. PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
