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

When the ptfe waterproof breathable membrane is in the state of water vapor, the water particles are very small. According to the principle of capillary movement, they can smoothly penetrate into the capillary tube 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 cannot smoothly break away from the water droplets and penetrate to the other side, which prevents water penetration and makes the water permeable. The membrane has a waterproof function.

Suzhou New Material Technology Co., Ltd. is a high-tech enterprise specializing in the research, development, production and sales of ptfe waterproof breathable membranes. It has a group of professional polymer R&D teams, strong R&D capabilities, and multiple invention patent certificates and practical models. patent certificate.

And according to the user’s requirements, the key parameters of PTFE membrane technology such as speed ratio, pressure ratio, operating temperature, etc. can be optimized and combined. According to the ratio and pore-forming medium, the air permeability, thickness and void ratio can be achieved online. Control to meet the different requirements you need. You are welcome to come to the company for inspection or enter the store to consult us at any time.
