Material Notes:
TIMREX Primary Synthetic Graphite is produced in a unique highly controlled graphitization process which assures narrow specifications and unequalled consistent quality due to: monitoring of all production and processing stages, strict final inspection, and clearly defined development processes.TIMREX Primary Synthetic Graphite shows unique properties thanks to the combination of a consistent purity, perfect crystalline structure and well defined texture.Tribological and mechanical properties:High toughnessGood lubrication propertiesAdvantages and applications: Low friction coefficientLow wear of the counterpart and low self-wearGood transfer-film formationMedium electrical conductivityMedium density of brushes and partsSuitable for pitch-bonded and resin-bonded brushesInformation provided by TIMCAL
