PTFE high-efficiency filter paper is a polymer compound made of polytetrafluoroethylene. It is a microporous membrane made by calendering, extrusion, biaxial stretching and other methods using a special process.
The film also has excellent corrosion resistance, aging resistance and high temperature resistance, and the operating temperature can reach -150℃-250℃.
It has been widely used in many fields such as electronics, chemical industry, medicine, military, aerospace, clothing, environmental protection and so on.
?ptfe high-efficiency filter paper 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 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.
