How does ePTFE work and its application?

ePTFE working principle: In the state of water vapor, water particles are very small, according to the principle of capillary movement, can smoothly penetrate into the capillary to the other side, resulting in steam penetration phenomenon. When the water vapor condenses into water beads, the particles become larger, due to the effect of the surface tension of the water beads (water molecules "pull against each other"), the water molecules can not be smoothly separated from the water beads to penetrate to the other side, that is, to prevent the penetration of water, so that the permeable film has the waterproof function.
