 Medium temperature tar distillation residue pitch is part of the tar yield accounted for 54 ~ 56%, which is more than three-ring aromatic compounds and oxygen, nitrogen, sulfur-containing heterocyclic compounds and a small amount of polymer material composed of carbon. The molecular weight of the asphalt components between 200 ~ 2000 up to 3000. The softening point temperature pitch is based on different division. Softening point of 65 ~ 90 ℃ in the temperature of the asphalt.
