CARBON BLACK FEED STOCK (CBFS)
Carbon Black Feed Stock (CBFS) is a type of petroleum-based feedstock used in the production of carbon black, a reinforcing filler used in various industrial applications.
Definition: CBFS is a residual fuel oil, derived from crude oil refining, used as a feedstock for carbon black production.
