2017 hot sale Modified Coal Tar pitch used in Graphite Industries
1.Description:
Coal Tar Pitch is a kind of black block with brittleness and odor , which is lustrous at
normal temperature. It is poisonous and can be easily flamed when melting, and it
belongs to second-grade inflammable solid.
Property:
Coal Tar Pitch is obtained from powerfully processed coal tar. Compared to petroleum
asphalt, the adhesiveness is better. Coal Tar Pitch is high quality tar production with
high fixed carbon.It has excellent adhesion, waterproofing and resistance against
seawater, oil and various chemicals. In these properties, it is much better than petroleum
asphalt tar.

3.Application
It is used across the industries like Graphite Industries, Electrode Industries, Refractories & Foundry Chemicals.
Specifically it can be used to produce prebaked anode in the electrolytic aluminium industry,
high power electrode bar, painting, electrode and pitch coke. It also can be used as fuel and the
raw material of asphalt carbon black.
