Documented Uses & Background

• Used mainly in rubber (90%) and as a pigment (9%); [ACGIH] Carbon black is a manufactured material while soot is a waste product of combustion. Compared to soot, carbon black particles are more homogeneous and less biologically active. [AIHAJ 2001;62(2):218-28]
• Painting (Pigments, Binders, and Biocides) [Category: Paint]
• Lithography printing [Category: Hobbies]
• USED AS A PIGMENT FOR RUBBER TIRES, FOR PRINTING, STENCILING & DRAWING INKS; FOR LEATHER, STOVE POLISH, PHONOGRAPH RECORDS, FOR ELECTRICAL INSULATING APPARATUS.
• Finely divided carbon black is a plastics stabilizer from uv radiation.
