CARBON BLACK N220

Carbon black N220
1.Iodine absorption:122g/kg
2.DBP absorption:114 10-5m3/kg
3.Wet process
Modern carbon black products are direct descendants of early "lamp blacks" first produced by the Chinese over 3,500 years ago. These early lamp blacks were not very pure and differed greatly in their chemical composition from current carbon blacks. Since the mid-1970s, most carbon black has been produced by the oil furnace process, which is most often referred to as furnace black.
