H13 grade high-efficiency filter material has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
The product has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
H13 grade high-efficiency filtration material has a fibrillar microporous structure. The porosity of the membrane can reach more than 88% or even higher. Moreover, the membrane has 1.4 billion micropores per square centimeter, with a pore diameter range of 0.1um-0.5um, high-efficiency filter paper has high and low temperature resistance (-200℃-260℃), no aging, no splitting, no color change, and strong weather resistance after long-term use.
