Easy processing channel black

EPC black. Abbreviation for easy-processing channel black.

Channel black is characterized by lower pFl, higher volatile content, and high surface area. It has the smallest particle size of any industrial material. A few grades of channel blacks (HPC, MPC, or EPC corresponding to hard, medium, or easy processing channel) are used in the rubber industry. 

In the case of SBR, which cannot easily achieve bond formation, when 40 phr of easy processing channel (EPC) black is added the tack is reduced and then remains almost the same during mastication. The filler in this case further restricts chain mobility, reducing interfacial interactions and thus leading to lower tack. If an SBR can be synthesised with... 

In the 1960s, carbon blacks were mainly prepared by channel processes, and their acidic functions were present at about 10 eq/g, which allows relatively easy determinations but now, with furnace blacks, the surface acidic functions are generally of about 10 eq/g, and specific techniques (Bertrand and Weng, 1998) or drastic reaction conditions must be used (Custodero et al., 1992). Obviously, such delicate determination must be conducted on previously extracted black, in order to eliminate basic mineral impurities that would hinder any characterization of the rare acidic groups present on carbon black.
