PTFE high-efficiency filter paper is made from polytetrafluoroethylene (ptfe) suspended powder and is expanded and stretched to form a microporous film.

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, no aging, no splitting, no discoloration, and strong weather resistance after long-term use.

PTFE high-efficiency filter paper has excellent high temperature resistance and low temperature resistance. The melting point is 327 degrees Celsius and the decomposition temperature is 415 degrees Celsius. It can be used for a long time in the range of 200 to 260 degrees Celsius.

But a major disadvantage of PTFE is its immobility at high temperatures F.

It will not change from a high elastic state to a viscous flow state when it is above the melting point, and will not flow even if it is heated to the decomposition temperature, which makes it impossible to adopt the molding method of general thermoplastic materials.

PTFE has a low thermal conductivity and poor thermal conductivity.
