gPTFE Filament PackingHEROOS-540P An is made by Heroos special technique, high strength PTFE filament LENMENS pretreated with graphite impregnation. The packing contains more graphite content compared with normal gPTFE, it has very low friction and good thermal conductivity of graphite, The characteristics are similar to CGFO, just has cross-sectional density, and some particles of graphite on surface. it almost suits for most of chemical media. It is new style.APPLICATION:For use in pumps, valves, reciprocating and rotating shafts, mixers and agitators. Especially designed for services involving surface speeds and temperature higher than those normally specified for pure PTFE packings. Can be safely used in all chemical pump applications with the exception of molten alkali metals, fluoride, fuming nitric acid and other strong oxidizing agents. It is also against water, steam, petroleum derivatives, vegetable oil and solvents.
