ptfe gray base film is insoluble in strong acid and alkali. The organic solution also does not change in boiling nitronicotinic acid. It is a very excellent polymer material.
Under the historical background at that time, people did not have enough understanding of building energy conservation. In the 1970s, with the development of the world energy crisis outbreak, European and American countries are paying more and more attention to the issue of building energy conservation. Energy experts found that although this kind of breathable cushion allows water vapor to be discharged from the cast-in-place concrete roof, effectively solving the problems of moisture resistance and mold, a large amount of water vapor is discharged into the insulation layer, seriously damaging the thermal performance of the insulation material.
PTFE Gray Base Tape Membrane It is a microporous membrane made of polytetrafluoroethylene as raw material and using special processes such as calendering, extrusion, and biaxial stretching. Polytetrafluoroethylene membrane is a general term for membrane material products, and the air filter membrane used in pleated filter elements of vacuum cleaners and pleated filter elements of indoor air filters is one of them. It has high filtration efficiency, good filtration performance and small membrane pore size, which can meet the filtration efficiency level requirements of air filters.
