Coal Tar Pitch Grade

ALUMINIUM/ANODE GRADE PITCH :
Aluminium grade of pitch is used for manufacturing of Anodes (both pre-baked & soderberg) in Aluminium industries. It is used as a binding agent for the manufacture of high quality electrodes for electric arc furnace.


GRAPHITE GRADE
Binder pitchGraphite grade 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. The relatively large number of graphite grades available in today’s market can cause confusion for the potential consumer in deciding which type of graphite and which graphite grade is appropriate for a specific use.
