PTFE high-temperature membrane is generally made of polytetrafluoroethylene (ptfe) suspended powder as raw material, which is expanded and stretched to form a microporous film.
The high-temperature membrane has a fibrillar microporous structure with a porosity of more than 88%. There are 1.4 billion micropores per square centimeter. The pore size range is 0.1μm-0.5μm. It is resistant to high and low temperatures -200–+260 degrees and is not suitable for long-term use. Aging, no splitting, no discoloration, strong weather resistance.
This polytetrafluoroethylene film is laminated on various fabrics and substrates with a special process and can become a new filter material. The ptfe high temperature membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, It can filter all dust particles including bacteria to achieve advanced purification and ventilation.
