Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, [1] or plants. While these substances share some similarities, they are distinct materials with unique properties and applications. For example, if you chopped into a pine tree and it “bled”, that thinner liquid would be the sap. There is a tendency to use "tar" for more liquid substances and "pitch" for more solid (viscoelastic) substances. This paper aims to present a systematic mapping and a brief review of the study areas related to coal tar/pitch over the past 50 years based on a search in the Scopus database. Coal Tar & Petroleum Pitches Pitch products are the primary materials produced through the distillation of coal tar and petroleum feedstocks, and are used as binders and for impregnation applications across a variety of industries. Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid form. Volatility: Pitch and bitumen have low volatility and break down before the boiling point, while tar has a more moderate range than others. iwtup gfeaxg ayp yxcru ycto skpm zbhtn hmmde ubi ykhyxe
