Graphite, Carbon, Expanded Graphite Filaments
99%+ graphite filament, treated with a suspension of colloidal graphite and an inert lubricant at high temperatures or with PTFE treatment.
In centrifugal and rotary pumps, drive shafts reciprocating motion, agitators, reactors, mixers and valve stems.
For high temperatures, resistant to almost all chemical compounds, except strong oxidizers such as sulfuric acid and nitric acid vapors, should not be applied in the presence of liquid oxygen.
