Webamount of progr ess has been achieved by the industry to the point that carbon black is doubtless the most refined and best -controlled commodity available to the rubber industry. Basic Chemistry In the simplest terms, carbon black is essentially elemental carbon in the form of extremely fine particles having an amorphous molecular structure. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content. See more Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal and coal tar, vegetable matter, or petroleum products, … See more The highest volume use of carbon black is as a reinforcing filler in rubber products, especially tires. While a pure gum vulcanization See more All carbon blacks have chemisorbed oxygen complexes (i.e., carboxylic, quinonic, lactonic, phenolic groups and others) on their surfaces to varying degrees depending on the conditions of manufacture.
