Biaxial stretching process to produce ptfe high temperature filter membrane

PTFE high-temperature filter membrane is a filter membrane made by calendering, extrusion, biaxial stretching and other methods using a special process. PTFE high-temperature filter membrane is made of suspended polytetrafluoroethylene resin which is molded, sintered and cooled into a blank. Then it is made by turning and rolling.

The polytetrafluoroethylene microporous membrane is coated on various fabrics and substrates using a special process, which can become a new type of filter material.

PTFE high-temperature filtration membrane generally refers to a microporous film formed from polytetrafluoroethylene (ptfe) suspended powder after expansion and stretching.

PTFE high-temperature filtration membrane has a fibrillar microporous structure. The porosity of the membrane can reach more than 88% or even higher. Moreover, the membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um. —0.5um, PTFE high-temperature film has high and low temperature resistance (-200℃-260℃). It will not age, split, discolor, and has strong weather resistance after long-term use.
