What is the working principle of ptfe waterproof and breathable membrane?

In the state of water vapor, the water particles are very small. According to the principle of capillary movement, they can smoothly penetrate the capillary to the other side, thus causing vapor permeability.

When water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules “pull and compete” with each other), the water molecules cannot smoothly break away from the water droplets and penetrate to the other side. It is to prevent water penetration and make the breathable membrane waterproof.

It is a ptfe waterproof and breathable membrane manufacturer that specializes in R&D, production and sales.

The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.

It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
