Styrene, also known as ethenylbenzene, vinylbenzene, and phenylethene, is an organic compound with the chemical formula C6H5CH=CH2. This derivative of benzene is a colorless oily liquid that evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor. Styrene is the precursor to polystyrene and several copolymers. Approximately 25 million tonnes (55 billion pounds) of styrene were produced in 2010.
Styrene is also used as a diluent and reactive cross-linker for thermoset polyester resin, which is combined with a reinforcement (such as glass fiber) to form composite materials such as fiberglass. The styrene used in these products comes from factories located all around the U.S. and, indeed, around the world.ts molecular formula is C 8 H 8, meaning that it consists entirely of the elements carbon and hydrogen. Styrene is also known by several other names, including vinylbenzene, phenylethylene, cinnamene, Diarex HF 77, styrolene, styrol, and styropol.
