Characteristics of ptfe gray base film
Do you know the material ptfe gray base film? Today we will take a closer look. This material is currently widely used in many fields. It can be said that its scope of application is still very broad.
Chemical substance: hydrophilic (water-loving)/non-porous lamination or coating The layer moves water through chemical diffusion. Water molecules are positively charged, and hydrophilic PU is negatively charged, attracting water through the intermolecular spaces of PU. Because the ionic bonds are relatively weak, water will be pushed through this gap until the water vapor has completely passed through.
ptfe gray base film is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities, and at the same time has a relatively high Large throughput. The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. The pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, the filtration grade can reach E10-U16, and it can operate at a continuous operating temperature of 240°C and an instantaneous temperature condition of 260°C Down.

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.
