How to define rCB?
Char---Solid carbonaceous residue formed during carbonization of organic compouds.
Raw rCB---Solid material resulting from thermal decomposition of rubber goods which contain carbon black; exhibiting poor dispersion so requiring milling to become rCB.
Recovered carbon black --- Solid product recovered via thermal decomposition from rubber goods which contain carbon black,which is free of wire and fabric, and when
milled typically gives semi-reforcing properties in rubber.
Recovered carbon black pellet --- A relative large agglomerate mass that has been densified in spheroidal form to facilitate handling and processing.
A type of filler derived from post-consumer rubber goods(feedstock) via a variety of
thermal decomposition processes. This semi-reinforcing filler predominatly consisting of carbon, also containing inorganic compounding ingredients originating from the feedstock but is free of wire and fabric. This material, typically pelletized currently marketed under the name recovered carbon black(rCB), should not be confused with
“Raw rCB”which exhibits poor dispersion and minimal reinforcing properties when used
in rubber compounding.
