Teflon waterproof and breathable membrane, also called breathing paper, is a new type of polymer waterproof material.
In terms of production technology, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials. At the same time, from a quality perspective, waterproof and breathable membranes also have functional characteristics that other waterproof materials do not have.
The principle of waterproof and breathable membrane is very simple. Water vapor can smoothly penetrate from one side to the other based on the principle of capillary movement.
The pore size of Teflon waterproof and breathable membrane can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are hundreds of millions of micropores per square centimeter.
It can effectively isolate water points, and the waterproof grade can reach IPX7 or above.
Protect electronic instruments from becoming unusable due to moisture or water.
Compared with other breathable filter materials, it has excellent air permeability. It is difficult to form a thick dust layer on the surface of the film, and the dust can be naturally peeled off.
The company has always implemented the tenet of “quality first, reputation first”. We have a complete service system, caring before sales, attentive during sales, and assured after sales! The company can provide samples and arrange sales personnel for door-to-door service if there are other requirements.
