product description

Product Description of Styrene CAS#100-42-5

Styrene is a widely used chemical compound with the molecular formula C8H8 and the structural formula CH2=CHC6H5. It is also known by names such as styrol, vinylbenzene, phenylethene, phenylethylene, and styreen. Its structure consists of a benzene ring attached to a vinyl group. At room temperature and pressure, styrene is a clear, colorless liquid. It is an essential monomer for the production of synthetic rubber, adhesives, and plastics, including styrene sheets.


Product Application of Styrene CAS#100-42-5

Styrene is a core monomer for synthetic rubber (SBR), plastics (polystyrene, ABS, SAN), adhesives and coatings. It forms thermoplastic elastomers (SBS, SIS) and acts as a crosslinker for polymer modification. Additional applications include styrene-acrylic emulsions, fragrances, pharmaceutical intermediates (analgesics, antitussives), dye intermediates, pesticides and metal plating additives.
