Description:Chinese GFO yarn is made by SINSTON special technique, it is different with traditional gPTFE yarn, double layers of graphited ePTFE with graphite sandwich. It contains more graphite content compared with normal gPTFE yarn, and no free particles of graphite on surface and therefore no contamination can occur. it has very low friction and good thermal conductivity of graphite, it almost suits for most of chemical media. It is Economical Chinese GFO
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.
