People have long noticed the outstanding properties of PTFE among polymer materials, such as excellent high and low temperature properties, outstanding chemical stability, and good dielectric properties. It is an ideal material for particle separation membranes under some harsh conditions. .
PTFE 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.
PTFE material, as a new type of membrane material, is widely used in the fields of clothing and industry.
The biaxial stretching process of PTFE microporous membrane gives the membrane good void characteristics, but at the same time, the mechanical properties of the membrane have anisotropic characteristics.
This anisotropic characteristic will directly affect the composite of the film and the performance of the composite material.
