Generally speaking, the porous polytetrafluoroethylene membrane produced by Teflon film manufacturer has a fibrillar shape With a microporous structure, the porosity of this membrane can reach over 88% or even higher, and there are 1.4 billion micropores per square centimeter, with the pore diameter ranging from 0.1um to 0.5um. Let’s find out today.
Because Teflon membrane has excellent flexibility and excellent flex resistance, it can maintain these properties over a wide temperature range without losing Originally has excellent chemical resistance. Make it resistant to solvents, acids and alkalis, and can even be cooked in strong acids and alkalis without losing the strength of the film. The water vapor permeability of Teflon film is very low, and the vapor permeability to air and most organic compounds is also very low (removing esters and ketone organic compounds).
Teflon film manufacturerProducts are made of polytetrafluoroethylene materials through mixing and extrusion , extrusion, calendering, biaxial stretching and other special processes. The porosity of the membrane can reach more than 88% or even higher, and the membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5um. The high-efficiency filter paper has high and low temperature resistance (-200℃ -260℃), it will not age, split or discolor after long-term use and has strong weather resistance.
