We all know that temperature changes, dust, dirt and moisture can have a considerable impact on some electronic component products.
In order to effectively solve this problem, people will use some waterproof and breathable membranes, and ptfe waterproof and breathable membrane is one of them.
Waterproof and breathable membrane (English abbreviation: Teflon or [PTFE, F4]), is known/commonly known as the “King of Plastics”, with Chinese trade names of “Teflon”, “Teflon” (teflon), “Teflon” “Teflon”, “Teflon”, “Teflon”, etc.
It is a polymer compound made of tetrafluoroethylene. The ptfe waterproof breathable membrane has excellent chemical stability and corrosion resistance (it is one of the most corrosion-resistant materials in the world today, except for molten metal sodium. Except for liquid fluorine, it is resistant to all other chemicals and does not change when boiled in aqua regia. It is widely used in various applications that require resistance to acids, alkalis and organic solvents), sealing, high lubrication and non-stickiness, electrical insulation and good resistance. Excellent aging endurance and temperature resistance (can work for a long time at temperatures from +250°C to -180°C).
The ptfe waterproof and breathable membrane is prepared using 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 alkalis, 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.
Our company can realize online control of air permeability, thickness and porosity according to the ratio and pore-forming medium to meet the different needs of users.
