Structural characteristics of ptfe high temperature filtration membrane
PTFE high-temperature filtration membrane generally refers to a microporous film formed from polytetrafluoroethylene (ptfe) suspended powder after expansion and stretching.
PTFE high-temperature filtration membrane 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 size range of 0.1um. —0.5um, PTFE high-temperature film has high and low temperature resistance (-200℃-260℃). It will not age, split, discolor, and has strong weather resistance after long-term use.
PTFE high-temperature filter membrane can be compounded on various fabrics and substrates using special processes, and it can 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.
