Teflon microporous membrane manufacturerPolytetrafluoroethylene microporous membrane, referred to as ptfe microporous membrane, is polymerized from the monomer tetrafluoroethylene The resulting perfluorinated polymer. In its molecular structure, the carbon atom is surrounded by four fluorine atoms. Since the covalent radius of the fluorine atom (0.064nm) is larger than the radius of the hydrogen atom (0.028nm), the fluorine atoms can be arranged to surround the carbon chain, and because Fluorine atoms repel each other, so that the entire macromolecular chain does not have a zigzag shape like a hydrocarbon molecular chain, but a helical structure similar to the human DNA helix. Outside the carbon chain skeleton of ptfe, which is susceptible to chemical attack, a tight and complete structure is formed. The “fluorinated” protective layer prevents the PTFE main chain from being invaded by any external reagents, giving PTFE incomparable solvent resistance, chemical stability and low cohesive energy density that other materials cannot match. This helical structure determines the chemical resistance of PTFE.
The production of polytetrafluoroethylene microporous membranes takes advantage of the oil absorption and insolubility of polytetrafluoroethylene plastic resin and the volatile nature of olefin materials The characteristics of the polytetrafluoroethylene plastic form micropores; taking advantage of the plasticity characteristics of polytetrafluoroethylene plastic before the curing temperature, bidirectional stretching is carried out within the processing range of the process temperature range, and finally it is sintered and solidified in a high-temperature atmosphere to become a 0.04mm thick plastic Breathable but water-proof PTFE microporous membrane.
