How are the products of PTFE membrane manufacturers made?

The products of PTFE membrane manufacturers are made of polytetrafluoroethylene (ptfe) materials through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.

The porosity of this membrane can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore size ranging from 0.1um to 0.5um. The high-efficiency filter paper has high and low temperature resistance ( -200℃-260℃), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.

The polytetrafluoroethylene microporous membrane is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities while having a large flux.
