High and low temperature resistant material ptfe waterproof and breathable membrane
PTFE waterproof and breathable membrane not only enhances air tightness and water tightness, but also has unique breathability properties that can quickly discharge water vapor inside the electronic structure and protect the performance of electronic products, thereby truly reducing the loss of electronic parts and avoiding unnecessary cost, and perfectly solves the problem of waterproof, breathable and sound-permeable environmentally friendly new energy-saving materials.
PTFE waterproof and breathable membrane is prepared by biaxial stretching process and is commonly known as the “King of Plastics”.
This material has a microporous structure with staggered fibers, high porosity, small and uniform pore size, finer molecular weight and cleaner.
It has properties such as high temperature resistance, alkali resistance, and hydrophobicity.
It is widely used in air filtration, aviation, electronics, electrical appliances, chemical industry, machinery, construction, textile and many other fields.
In the state of water vapor, the water particles are very small, and these water particles can penetrate all the way down the capillary to the other side, causing vapor permeability.
If water vapor condenses into water droplets, the particles will become larger, and the surface tension of the water droplets will act, and the water molecules will not be able to smoothly leave the water droplets, penetrate and reach the other side. In other words, this process This can prevent water penetration, allowing the waterproof and breathable membrane to truly have a waterproof function.
