STYRENE MONOMER
STYRENE MONOMER
Chemical Formula: C?H?
Molecular Weight: 104.15 g/mol
Description:
Styrene Monomer is a clear, colorless to slightly yellow, oily liquid with a sweet, aromatic odor. It is an organic compound used primarily as a monomer in the production of polystyrene and copolymers. It readily undergoes polymerization and must be stabilized with inhibitors during storage. Styrene Monomer is highly versatile and widely used in plastics, rubber, and resin industries.
Applications:
-
Plastics Industry: Primary raw material for manufacturing polystyrene, ABS (Acrylonitrile Butadiene Styrene), and SAN (Styrene Acrylonitrile) plastics.
-
Rubber Industry: Used in the production of SBR (Styrene-Butadiene Rubber) for tires and other rubber products.
-
Resins & Coatings: Component in unsaturated polyester resins and protective coatings.
-
Fiberglass Industry: Used in reinforced plastics and composite materials.
-
Adhesives & Paints: Serves as a reactive solvent and viscosity reducer.
