To put it simply, 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 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.
?ptfe waterproof and breathable membrane is a microporous membrane made of polytetrafluoroethylene as raw material, using special technology, calendering, extrusion, biaxial stretching and other methods.
The pore size of this membrane ranges from 0.02um to 0.2um, and the porosity reaches more than 88%.
The main advantages of polytetrafluoroethylene waterproof and breathable membrane are as follows: 1. It has good high temperature resistance. The working environment temperature of the waterproof breathable membrane can reach up to 250℃.
Good low temperature resistance and good toughness.
Two: High lubrication effect, good corrosion resistance effect, ptfe waterproof breathable membrane can show resistance to most chemicals and solvents, strong acids, alkalis and various organic solvents.
