PTFE hose
ElringKlinger Kunststofftechnik
Thanks to its exceptional chemical, thermal and dielectric properties, PTFE ranks at the top of the list of fluoro-plastic materials. These properties enable manifold problem solutions in the chemical, electrical and medical sectors.
Due to the stable combination of fluorine and carbon atoms and the nearly complete shielding of the carbon chain by the fluorine atoms PTFE has nearly universal chemical resistance. This property is attributable to the material's molecular structure. The straight carbon chain is completely covered with a layer of fluorine atoms. Chemical reactions between PTFE and other substances are limited to a few exceptions: alkali metals in melted or dissolved form attack the polymerizate, causing a brown discoloration. Also, elementary fluorine and chlorinetrifluoride effects PTFE at higher temperatures and pressures. For some years, paste compounds have been used increasingly as well. The most common compounds are PTFE-carbon, PTFE-glass, PTFEbronze and PTFE-graphite. Pure-white material will continue to be used wherever the PTFE's outstanding chemical and thermal resistance and adhesive properties are required. Glass-filled material is preferably used when wear resistance, which is required with industrial applications in particular, should be increased.
