Processing technology of polytetrafluoroethylene composite membrane

Simply speaking, polytetrafluoroethylene composite membrane is made of polytetrafluoroethylene (ptfe) as raw material , puff it into a microporous film, and then use a special process to coat the film on various fabrics or paper substrates to make it a new type of material.

Geomembrane is made of high-density polyethylene material and has good anti-seepage, ductility, corrosion resistance and other properties. The thicker the geomembrane, the The higher the strength, elongation and other indicators of the geomembrane, the higher the price of course. Therefore, when choosing, you should choose a geomembrane with an appropriate thickness according to the project, so as to achieve the effect and save money at the same time.

Polytetrafluoroethylene composite membrane refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and through calendering, extrusion, biaxial stretching and other methods. This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties. According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, there are up to hundreds of millions of micropores per square centimeter, and the filtration grade can reach H13-U16 , can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
