Waterproof and breathable material ptfe two-way stretch film
ptfe biaxially stretched film is a microporous membrane made of polytetrafluoroethylene as raw material, using special technology, calendering, extrusion, biaxial stretching and other methods. It is also a new type of polymer waterproof material. .
In terms of production technology, the technical requirements of PTFE membrane are much higher than those of general waterproof materials; in terms of quality, PTFE biaxially stretched membrane also has functional characteristics that other materials do not have.
?PTFE biaxially stretched film has high-density micropores, which is refreshing and breathable. The film has the excellent characteristics of micropores, hydrophobicity and non-moisture absorption. It is not easy to accumulate water vapor and can quickly wick away moisture, keeping it fresh and breathable for a long time.
Surface filtration can be achieved. This is because the microporous membrane has a microporous structure and no direct holes on the surface, so that dust cannot enter the interior of the membrane or the substrate through the surface of the membrane, so that only gas passes through and the dust or materials are removed. trapped on the surface of the membrane.
?Product quality is constantly improving, and it occupies a dominant position in the market with its unique and stable performance.
And it has a complete set of domestic advanced production lines, which can be customized according to user requirements.
The key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. are optimized and combined. According to the ratio and pore-forming medium, the air permeability, thickness and void ratio can be adjusted online to meet your different requirements. .
