The raw material of ptfe high-efficiency filter paper is granular PTFE (polytetrafluoroethylene) resin, which is a homopolymer of polytetrafluoroethylene. It is a microporous polytetrafluoroethylene film prepared through a special biaxial stretching process.
It can be compounded on various fabrics and substrates using special processes to become a new type of filter material.
The pore size of the membrane is small, the distribution is very uniform, and the porosity is large. Therefore, the membrane can filter all dust particles including bacteria while ensuring air circulation, thereby achieving the purpose of advanced purification and ventilation.
PTFE high-efficiency filter paper 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 ranging from 0.1um to 0.5um, ptfe 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.
? is a manufacturer specializing in the production of membrane materials and various membrane-coated filter materials. Our membrane materials are all imported raw materials, with a full set of domestic advanced production equipment and advanced production technology. Our products have passed ISO9001 quality management system Certification and testing standards strictly follow the EU standard EN1822, and membrane products are tested using the MPPS method.
