Polytetrafluoroethylene, also known as waterproof and breathable membrane, is generally called “non-stick coating” or “easy-to-clean material”; it is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene.
This material is acid-resistant, alkali-resistant, resistant to various organic solvents, and is almost insoluble in all solvents.
At the same time, the waterproof and breathable membrane has the characteristics of high temperature resistance. Its friction coefficient is extremely low, so it can not only be used for lubrication, but also become an ideal coating for easy-to-clean pans and the inner layer of water pipes.
PTFE waterproof and breathable membrane is a new type of polymer waterproof material.
In terms of production technology, the technical requirements of PTFE waterproof and breathable membrane are much higher than those of ordinary waterproof materials. At the same time, from a quality point of view, PTFE waterproof and breathable membrane also has functional characteristics that other waterproof materials do not have.
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, thereby making the breathable membrane waterproof.
