High density graphite ring for high temperature
Our Material graphite rings are manufactured from pure graphite tapes. High thermal & dimensional stability, low gas fluid permeability, low thermal expansion and high chemical resistance it is nonabrasive with a low coefficient of friction engineer each ring. Graphite shall have flexibility compactability and resiliency.
