TIMCAL TIMREX® T800 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. Advantages and applications: Suitable especially for organic bonded clutch facings (paper, fiber) and organic brake linings (semimetallic, non-metallic, low-metallic). Good lubrication properties Reduction of the friction level and smoothing of the friction coefficient Good thermal conductivity Reduction of hot spots and difference thickness vibration (DTV) by spring back and good thermal conductivity High effectivness of wear-reduction at relatively low graphite concentrations Good damping behaviour due to internal lubricity and micropores - noise reduction Good wettability with organic binders and high adhesion strength between binder and graphite particle Information provided by TIMCAL
