Specialty Graphite---Vibration Molded Graphite (VMG series)
VMG series medium grain graphite materials have an exceptionally homogeneous structure, almost isotropic properties and low ash content. They can be manufactured in large sizes. Further processing, for example impregnation is possible. VMG series coarse grain graphite materials are available for economical applications.
