128683-24-9 Usage
General Description
Bitumen is a viscous, black, hydrocarbon-based liquid or solid formed from the distillation of crude oil. It is composed predominantly of highly condensed aromatic polycyclic compounds and has a high molecular weight, making it a heavy, dense substance. Bitumen is commonly used in the construction and automotive industries as a binding agent in asphalt for roads and roofing materials, as well as in waterproofing and sealing applications. It is also used in the production of various industrial and consumer products, such as adhesives, paints, and insulation. Despite its usefulness, bitumen poses environmental and health risks due to its high levels of toxicity and potential carcinogenicity.
