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.
