HSN Code : 29025000 Synonyms : Ethenylbenzene, Cinnamene, Cinnamenol, Ethenylbenzene, Phenethylene, Styrol, Vinylbenzene, Vinylbenzol. CAS No. : 100-42-5 Molecular Formula : C8H8 Application : Styrene is a colorless to yellowish oily liquid with a distinctive aromatic odor. It is sparingly soluble in water but soluble in alcohols, ethers and carbon disulfide. This valuable monomer is flammable, reactive and toxic. Styrene Monomer is a light liquid. It has a low vapour pressure and high refractive index. Styrene polymeric form is used in making corrosion-resistant pipes and tanks. Styrene is used in making Composite products, these products are known as fiber-reinforced polymer composites (FRP). These components are used in making automobile components. Styrene is used to make products such as rubber, plastic, insulation, fiberglass, pipes, automobile parts, food containers, and carpet backing. Most of these products contain styrene linked together in a long chain (polystyrene) as well as unlinked styrene.
