Furnace Black Carbon Black
Furnace black is a type of carbon black produced in a furnace by partial combustion of hydrocarbons, resulting in fine particulate carbon with high surface area. It falls under HTS 2803.00.00 as a form of carbon black not elsewhere specified, used primarily as a reinforcing filler in rubber products like tires.
Thermal Black Carbon Black
Thermal black carbon black is manufactured by thermal decomposition of hydrocarbons in the absence of air, yielding a coarser particle size than furnace black. Classified in HTS 2803.00.00 as other forms of carbon black, it's used in plastics and as a pigment in inks.
Channel Black Carbon Black
Channel black carbon black is made by impinging hydrocarbon flames against iron channels, producing high-color fine particles. It qualifies under HTS 2803.00.00 for pure carbon blacks used in inks and high-quality pigments.
Graphitized Carbon Black Powder
Graphitized carbon black undergoes heat treatment to develop partial graphitic structure while remaining primarily amorphous carbon. Classified in HTS 2803.00.00 as other forms of carbon, excluding artificial graphite, for use in specialty rubbers.
