Teflon waterproof and breathable membrane for multi-field filtration applications
Teflon waterproof and breathable membrane is generally produced by an intermediate layer of polyolefin microporous membrane and two layers of polymer materials through advanced thermal composite technology. The product is laid on the building roof insulation layer to enhance the water tightness of the building. At the same time, with its unique breathable function, the moisture vapor in the enclosure can be smoothly discharged, thereby effectively maintaining the service life of the building, playing the functions of heat preservation, energy saving, and improving the living environment.
?Teflon waterproof and breathable membrane is made by special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
Due to the characteristics of ptfe fibrillation, when performing unidirectional stretching (i.e. longitudinal stretching), the ptfe polycrystalline aggregates begin to extend and form some fibrils. The fibrils are parallel to the stretching direction. At the same time, the fibrils The length increases.
The cross-section of ptfe fibrils is wide and thin, its maximum width is about 100nm, and the smallest fibril is ?0.5??1.0nm.
? Products are widely used in various fields and are different from other manufacturers.
Our company can customize according to user’s requirements.
The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .
