The ePTFE film covering material is the filter material obtained by the thermal composite of ePTFE microporous film and imported non-woven cloth. It has the reliable filtration grade of H13-U16, low wind resistance and low energy consumption.

Compared with fiberglass and electret filtration materials, ePTFE coated material can well achieve the balance between the wind resistance and the rejection rate. It has different levels of ULPA, HEPA and higher filtration, and the filtration accuracy can be adjusted to meet the requirements of different customers for filtration accuracy. The modified material is resistant to strong acid and alkali and has good chemical resistance. The product itself will not reduce the performance because of cleaning, and can be used repeatedly for a long time, which can better reduce the consumption of materials and save the production cost. It is widely used in clean rooms and industrial dust removal.
