Introduction:
Carbon black is an amorphous form of carbon. Light, loose and very fine black powder, with a very large surface area, ranging from 10 to 3000m2/g, is the product of incomplete combustion or thermal decomposition of carbon-containing substances (coal, heavy oil, fuel oil, etc.) under the condition of insufficient air. Specific gravity 1.8-2.1.
We may produce more than 20 grades carbon black like N220, N234, N330, N326, N339, N375, N550, N539, N660 T300,C500,P8 ect. And following GB3778-2011 & ASTM-D Stanard.
