Teflon microporous membrane is a perfluorinated polymer polymerized from the monomer tetrafluoroethylene and can be used for a long time in the range of -200~250℃.
In its molecular structure, the carbon atom is surrounded by 4 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. Live, and because fluorine atoms repel each other, 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 of the carbon chain skeleton of Teflon, which is susceptible to chemical attack, a tight and completely “fluorinated” protective layer is formed, which protects the PTFE main chain from attack by any external reagents, making the Teflon microporous membrane unique Solvent resistance, chemical stability, and low cohesive energy density unmatched by other materials.
Teflon microporous membrane shows a high degree of chemical stability and is almost resistant to the intrusion of all acids and bases and other chemical substances. It also has outstanding non-stickiness, lubricity, electrical insulation properties, aging resistance and radiation resistance, etc. Features.
Therefore it is widely used in petrochemical, machinery, electronics, electrical appliances, construction, textile and many other fields.
Suzhou New Material Technology Co., Ltd. is a high-tech enterprise specializing in the research, development, production and sales of fluorine material films. It strives for excellence in product quality and occupies a dominant position in the market with its unique and stable performance.
The ptfe membrane materials produced by Suzhou ptfe film manufacturers use imported raw materials and have a full set of advanced production equipment; they adopt advanced production technology, have advanced clean rooms and independent composite slitting workshops, ensuring that Teflon microporous membrane production quality.
