Carbon Black has been produced by Orion's predecessors since 1862. It plays a crucial role in the rubber industry. When used in tires Carbon Black ensures a high resistance to abrasion, good road handling and ageing resistance. Carbon Black is also an important ingredient in the production of a multitude of other rubber goods like profiles, hoses and anti-vibration systems.
Carbon Black is nearly pure carbon. Today the most common method for producing Carbon Black is the Furnace Black Process. A liquid hydrocarbon feedstock is injected into a flame, which is generated by the combustion of a gaseous or liquid fuel in combination with preheated air. Under these conditions the feedstock decomposes and Carbon Black particles are formed. After separation of the process gas/Carbon Black mixture in filter systems, the Carbon Black powder is pelletized in order to improve handling properties. Alternative production processes working according to the same physico-chemical principle are the Lamp Black Process and the Degussa Gas Black Process, which provide Carbon Blacks with a unique combination of properties.
Carbon Blacks can be divided into:
Hard Blacks (synonyms: tread grades, reinforcing Carbon Black): a type of furnace Carbon Black having an average nitrogen surface area of 70 mn or greater. Soft Blacks (synonyms: carcass grades, semi-reinforcing Carbon Black): a type of furnace Carbon Black having a nitrogen surface area in the range of 21 to 69 mn. Thermal Blacks: produced under controlled conditions by the thermal decomposition of hydrocarbons in the absence of air or flames. Gas Blacks: Degussa process, high reinforcing capability, imparts scorch safety to compounds.
Specialty Carbon Blacks play a crucial role in a range of products including Plastics, Printing Inks, Adhesives and Sealants, Paints and Coatings. Beyond tinting and color, furnace black, gas black and lamp black can also impart other desired performance properties such as UV protection, conductivity and special effects. Among the specialty applications for Specialty Carbon Blacks are: lithium-ion batteries, non-impact printing, paper, PVC pipe, non-woven fabrics and metallurgy.
