Carbon Black has been produced by Xinyuan’s predecessors since 2004. In the rubber industry it plays a crucial role: When used in tires it ensures a high resistance to abrasion, good road handling and ageing resistance. Furthermore, Carbon Black is an important ingredient in the production of a multitude of rubber goods like profiles, hoses or anti-vibration systems.Carbon black N330
Carbon Black consists of 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 and the Degussa Gas Black Process, which provide Carbon Blacks with a unique combination of properties.
Carbon Blacks can be divided in:
• Hard Blacks (synonyms: tread grade, reinforcing carbon black): a type of furnace carbon black having an average nitrogen surface area of 70 m²/g or greater.
• Soft Blacks (synonyms: carcass grade, semi-reinforcing carbon black): a type of furnace carbon black having a nitrogen surface area in the range of 21 to 69 m²/g.
• 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.
