Polytetrafluoroethylene (PTFE) is commonly known as the “King of Plastics” and can also be called Teflon.
It is a new type of polymer compound polymerized from tetrafluoroethylene. PTFE microporous membrane has excellent low temperature resistance, alkali resistance, hydrophobicity and non-adhesion.
The biaxially stretched polytetrafluoroethylene microporous membrane has a microporous structure of interwoven fibers, with high porosity and small and uniform pore size.
Polytetrafluoroethylene microporous membrane 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.
?The company’s R&D center has always been committed to carrying out industry-university research cooperation with domestic universities and colleges on polytetrafluoroethylene film products. After years of painstaking research and development, it not only has strong R&D strength, complete testing methods and advanced experimental equipment, We have developed a series of PTFE films and derivative products that are superior to those of our domestic counterparts, with fruitful results. We have a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of membrane materials.
