Why is ptfe waterproof and breathable membrane waterproof?

When the waterproof breathable membrane is in the state of water vapor, the 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, 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, making the ptfe waterproof and breathable membrane truly have a waterproof function.

It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
