PTFE high-temperature filtration membrane is generally made of polytetrafluoroethylene (ptfe) suspended powder, 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 membrane is coated on various fabrics and substrates using a special process and can become a new type of filter material. The membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, it can filter bacteria including bacteria. All dust particles inside are removed to achieve advanced purification and ventilation.
