Polytetrafluoroethylene waterproof and breathable membrane (ptfe) refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and processed by calendering, extrusion, and biaxial stretching.
This waterproof and breathable membrane has excellent characteristics such as high peel strength, large air permeability, and uniform pore size distribution.
To put it simply, the working principle of polytetrafluoroethylene (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 to the other side, and occur The phenomenon of vapor permeability.
If water vapor condenses and turns 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 This can prevent water penetration, allowing the waterproof and breathable membrane to truly have a waterproof function.
