PTFE base tape membrane 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, baseband membranes also have functional characteristics that other materials do not have.
?Using the pore-forming characteristics of polytetrafluoroethylene plastic resin, the ptfe base tape film is made by biaxial stretching method.
The surface of the membrane can reach more than one billion micropores per square centimeter. The diameter of each micropore (0.1μm-0.5μm) is hundreds of times smaller than the diameter of water molecules (20μm-100μm) and smaller than the diameter of water vapor molecules (0.0003 μm-0.0004μm) is tens of thousands times larger, allowing water vapor to pass through, but water droplets cannot pass through. This microporous structure can be used to achieve excellent waterproof and breathable functions.
?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. .
