PTFE MEMBRANE
Micro-Porous PTFE membranes are crystalline state polytetrafluoroethylene material which is extruded to film with a very high draw velocity at the temperature close to its melting point. After cooling, the film is stretched again in order to make the film own the characteristic of three-dimensional structure. Its aperture, thickness and porosity can be adjusted under the requirement during drawing. Aperture is generally 0.2-15¦Ìm, thickness 15-30¦Ìm, porosity high to 80-97%. The micro apertures of membrane are anomalous, porosity is high, orientations of nodes are generally consistent, arranging in strip order.
