Unipetrol A+ High-Conductive Carbon Black Chezacarb
Categories:	Carbon; Carbon Black
Material Notes:	Carbon black Chezacarb is manufactured by gasification of heavy petroleum residues by partial oxidation in Shell reactors. It is produced in the form of pellets of size 0,5 - 2,5 mm. Product is not classified as dangerous according to EC Directives. Carbon black Chezacarb is made in three sorts: A+, A and B. There are suitable mostly for modification of conductance and heat conductivity in plastics and rubber, due to their high specific surface and high poresity. Information provided by Unipetrol RPA
