Since ancient times, materials that have both breathability and waterproofness have often not been able to achieve perfection. This has been a problem that has not been solved for a long time. However, it has been satisfied in the new material of Teflon waterproof and breathable membrane, making everything possible. Everything becomes simple.
The expanded polytetrafluoroethylene (ePTFE) waterproof, breathable and sound-permeable film has 0.1-1.0 micron micropores. The micropore diameter is about 1000 times that of water vapor, allowing air to pass smoothly, effectively dissipating heat and preventing the inner wall of the product from forming. Fog balances the air pressure in the internal and external spaces. At the same time, the pore diameter is thousands to tens of thousands of times the diameter of water droplets, making it impossible for moisture to pass through, effectively protecting sensitive components, avoiding liquid erosion, and extending the service life of the product.
Mobile phones and other portable radio devices are likely to be exposed to water and dust during use. Install Teflon waterproof and breathable membranes on the ports of these devices to prevent dust and splashing water (soda, coffee, etc.) drinks) and briefly fall into the water; at the same time, the breathability allows the radio device to discharge battery exhaust gas and balance pressure when in use.
The Teflon waterproof and breathable membrane made by mechanically stretching PTFE material by Suzhou PTFE filter membrane manufacturer can ensure the 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.
