TIMCAL TIMREX® KS150 Primary Synthetic Graphite
Categories:	Carbon; Graphite; Other Engineering Material; Additive/Filler for Polymer
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: Medium toughness Good lubrication properties Advantages and applications: Low friction coefficient Low wear of the counterpart Good transfer-film formation High electrical conductivity Suitable for pitch-bonded and resin-bonded brushes Copper/bronze bearings Copper friction parts copper clutch facings Information provided by TIMCAL
Key Words:	CAS Number 7782-42-5
