DESCRIPTION:Medium Temperature Coal pitch is Softening Point 80-90 Coal Tar Pitch For Electrolytic Aluminium
Medium temperature coal pitch had Improved chemical compatibility between carbonaceos aggregrate (CPC) and the pitch - it is possible to manufacture long durable and best performing graphite electrodes. Mnufactured electrodes can be used in high capacity electric arc furnaces in hassel free operation.

COAL TAR PITCH APPLICATION
Medium Temperature Coal pitch used as binder material for manufacturing of graphite electrodes Impregnating pitch. It is used in Graphite electrode, nipple impregnation and UHP grade electrode manufacture. Graphite grades now benefit from much finer grain size.
