Iran  Bitumen 60 / 70

Bitumen is a non-crystalline viscous material, black or dark brown, which is substantially soluble in carbon disulphide (CS2), possessing adhesive and water-proofing qualities. It consists essentially of hydrocarbons and would typically comprise at least 80% carbon and 15% hydrogen, the remainder being oxygen, sulphur, nitrogen and traces of various metals.

 

60-70 Bitumen

The bitumen is provided during the process of oxidation of vacuum bottom in bitumen production units. Due to its medium air blowing and penetration, is used in mild areas.
