General Characteristics
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.
Product group Carbon black Chezacarb is made in the three sorts: A+, A, and B. They are suitable mostly for modification of conductance and heat conductivity in plastics and rubber, due to their high specific surface and high poresity.
The product is not classified as hazardous pursuant to Act No. 350/20011 Coll. and corresponding EU legal regulations (Regulation (EC) No 1272/2008 CLP, Directive No 67/548/EHS or Directive No 1999/45/EC.
