What is the pore size and high and low temperature resistance of ptfe composite filter paper?

PTFE composite filter paper is made of polytetrafluoroethylene (PTFE) material 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 range of 0.1um-0.5um, and 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.
