Brief introduction of PTFE film

PTFE membrane is made from polytetrafluoroethylene dispersion resin, premixed, extruded, rolled, biaxially stretched and other special technology, and it is divided into clothing membrane, Pu micro waterproof membrane, filtration membrane and purifying membrane.


Brief introduction and microstructure of PTFE film

The PTFE film is a microporous film made of polytetrafluoroethylene as a raw material, using a special process, such as calendering, extrusion, and biaxial stretching. PTFE film can be divided into clothing film, air filtration membrane and air purification film for use. The PTFE membrane has a fibrous microporous structure, with a porosity of more than 85%, 1 billion 400 million micropores per square centimeter, and an aperture of 0.02mm-15mm.
