DESCRIPTION:Coal tar pitch has obtained from deep process of coal tar or general coal pitch

Coal tar pitch used to produce coke (ash content less than 0,25-0,50%) and pitch-binder used in the production of anode mass in the production of aluminum, electrodes and electrode rods, graphitized products, coalgraphitic blocks, etc.; for manufacturing briquetted coal fuel, rolled roofing, pitch plastic and paint for pipes corrosion protection, tanks, metal constructions, etc. middle temperature coal-tar pitch as binder is modified by p-tert benzaldehyde

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.
