• Detailed Description:

  Cas No. :8052-42-4 Physical and chemical properties
  The modified high temperature coal tar pitch is a black solid consist of fused ring aromatic hydrocarbons and macromolecular resins, which contains oxygen, nitrogen and sulfur heterocyclic compounds and a small amount of polymer carbon material.it can be solidified into a brittle solid in shell-like fracture at a certain temperature (1-5cm) without thermal effect. It is brittle black lumps under room-temperature and can be converted into liquid when heating, with characteristics of shiny, toxic and in a slight odor. Its flash point is 204.4°C and boiling point is no higher than 470°C . Melting point around 100-150°C and 1.25-1.35g/cm3 density.
