Chemical Name: 中温沥青, English Name: Soft Pitch. It is a black solid at normal temperature, and is solidified into a very brittle solid with shell-shaped fracture, presenting a glass phase; it has no certain melting point, and melts within a certain melting point, with no thermal effect at solidification. Pitch has extremely complex components, most of which are aromatic hydrocarbons with more than three rings, as well as heterocyclic compounds containing oxygen, nitrogen, and sulfur and other elements, and a small amount of polymer carbon substances.


Soft Pitch is a part of tar distillation residue, and the yield is 54 to 56% of the tar; it consists of aromatic compounds with more than three rings, heterocyclic compounds containing oxygen, nitrogen and sulfur, and a small amount of polymer carbon substances. The molecular weight of the pitch components is 200~2000, 3000 at highest. Soft pitch is classified according to different softening points. Soft pitch has a softening point of 65 ~ 90 ° C.
