Carbon black subtypes are acetylene black, channel black, furnace black, lamp black and thermal black is virtually a pure form of carbon manufactured through incomplete combustion of hydrocarbons such as FCC tar, coal tar, or ethylene cracking tar, and contains more than 95% pure carbon, other components are oxygen, hydrogen and nitrogen.

The black particles are 10nm to approximately 500nm big and fuse into chain-like aggregates, which define the structure of individual Carbon Black grades. Depending on the production process Carbon Black types differ in size, surface chemistry, porosity and many other characteristics. During the after-treatment process the oxygen percentage within the Carbon Black can be changed according to the required needs. 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.

Carbon Black grades are determined by industry-wide standards which have been developed by the German Institute for Standardization (DIN), the International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM), whereas ASTM widely used, especially for Rubber Carbon Black grades

Carbon Black being one of the most important industrial chemicals manufactured worldwide, carbon black finds application in an array of industrial goods and products including Tyres, Rubbers, Inks, Pigment, Paints, Coating, Rubber, Plastic Master Batches, Wire & Cable, Fibre, Mechanical Rubber, Plastics, Food, etc.

Tyre industry is the leading consumer of carbon black, globally, as the industry uses it as a reinforcing filler to improve the longevity of tyres. It helps conduct heat away from the tread and belt area of the tyre, reducing thermal damage and increasing tyre life. Carbon black particles are also employed in some radar absorbent materials and in printer toner.

About 20% of world production goes into belts, houses, and other rubber goods. The balance is used in links and as a pigment for products other than tyres. The highest volume use of carbon black is as reinforcing filler in rubber products, especially tyres.

Based on application carbon black can be broadly divided into

  • Rubber Carbon Black
  • Speciality Carbon Black
  • Inks, Coatings and Paints
  • Cables, Wires and ESD
  • Plastics and Pipes
  • Films
  • Moldings
  • Fibres
  • Food
  • Mechanical Rubber
