The relative molecular weight of polytetrafluoroethylene is relatively large, ranging from hundreds of thousands to tens of millions (the degree of polymerization is about 104, while that of polyethylene is only about 103). The general crystallinity is 90-95% and the melting point is 327-342 . The CF2 units in polytetrafluoroethylene molecules are arranged in a zigzag manner. Because the radius of fluorine atom is slightly larger than that of hydrogen, the adjacent CF2 units cannot be fully trans oriented, but form a helical twisted chain, which is almost covered by fluorine atom.


PTFE base band film is a kind of microporous film made by special processing technology, calendering, extrusion and biaxial stretching. The film has excellent air permeability, corrosion resistance, aging resistance and high temperature resistance. The porosity can reach 80% ~ 90%, and after high-temperature heat setting treatment, the micropore structure is stable, which can effectively intercept dust particles. Moreover, it has small and uniform pore size, surface filtration mechanism, easy dust removal, strong hydrophobicity, low surface energy, and good non adhesion ability. It can effectively remove the accumulated dust on the surface. It can recover its performance by washing or back blowing, and greatly prolong its service life, The filtration efficiency can reach 99.999995%.


The PTFE baseband membrane produced by youkefa manufacturer adopts imported raw materials, has a full set of advanced production equipment, adopts advanced production equipment, has advanced clean room and independent composite slitting workshop, which ensures the production quality of PTFE membrane; The production test instrument imported from the United States is used to test the quality of PTFE film, and has passed the international SGS test certification and ISI test certification.
