PTFE waterproof and breathable membrane refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and processed by calendering, extrusion, biaxial stretching and other methods.
This waterproof and breathable membrane has excellent characteristics such as high peel strength, large air permeability, and uniform pore size distribution.
The working principle of ptfe waterproof and breathable membrane is: in the state of water vapor, water particles are very small, and these water particles can penetrate along the capillary tube to the other side, causing vapor permeability.
If water vapor condenses into water droplets, the particles will become larger. In addition, 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 It can prevent the occurrence of water penetration, so that the ptfe waterproof and breathable membrane truly has the waterproof function.
