Styrene CAS#100-42-5

Styrene is a certain organic chemical compound having the chemical formula C8H8 and structural formula CH2=CHC6H5, also known as styrol, vinylbenzene, phenylethene,phenylethylene,styrene,styreen and so on. Its chemical structure is made up of a benzene ring bonded onto a vinyl group . At room temperature and pressure, styrene is a clear, colorless liquid. Styrene is an important monomer of synthetic rubber, adhesives and plastics, such as styrene sheet.

Product Application Of Styrene CAS#100-42-5

STYRENE, is the simplest and by far the most important member of a series of aromatic monomers. Also known commercially as styrene monomer (SM), styrene is produced in large quantities for polymerization. It is a versatile monomer extensively used for the manufacture of plastics, including crystalline polystyrene, rubber-modified impact polystyrene, expandable polystyrene, acrylonitrile– butadiene–styrene copolymer (ABS), styrene–acrylonitrile resins (SAN), styrene–butadiene latex, styrene–butadiene rubber (SBR), and unsaturated polyester resins.
