Styrene CAS#100-42-5

Basic Information

Styrene
C8H8
clear, colorless liquid

Styrene is a clear, colorless vinyl aromatic liquid and an essential monomer for synthetic materials. Its benzene-ring and vinyl-group structure supports polymerization into styrene-based materials. It is used for synthetic rubber, polystyrene, ABS, SAN, thermoplastic elastomers, adhesives, coatings, styrene-acrylic emulsions, polymer modifiers, dye and pesticide intermediates, fragrances, and metal-plating additives.

product description

Essential Monomer for Synthetic Materials:Styrene serves as a key monomer in the production of synthetic rubber, adhesives, and plastics.


Versatile Industrial Applications:It is widely used in the manufacture of styrene-based sheets and other polymer products.


Clear and Colorless Liquid:At room temperature, styrene is a stable, transparent liquid, making it easy to handle and process.


Chemical Structure Benefits:The benzene ring bonded to the vinyl group provides desirable properties for polymerization and material performance.



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.
