What Is Styrene monomer (SM CAS 100-42-5)?
Styrene monomer is a colorless, oily liquid, also known as vinyl benzene, ethenylbenzene, that serves as a crucial building block in the chemical industry. It's a synthetic chemical derived from petroleum or natural gas by-products and is used to produce various plastics, synthetic rubbers, and resins.
Properties
Styrene (vinyl benzene, styrene monomer SM) 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 vapor pressure and high refractive index. It is chemically reactive and undergoes polymerization readily (by heat, light or peroxide catalysts).

What is liquid styrene used for?
Styrene monomer is an important raw material for industry because it is the chemical 'building block' for creating a multitude of versatile plastics and synthetic rubbers with beneficial properties including strength, durability, comfort, light weight, safety and energy efficiency.
The key styrene derivatives include:
Liquid styrene is typically converted or 'polymerised' into pellets which can be heated, fused and moulded into plastic components.
- polystyrene (PS)
- expandable polystyrene (EPS)
- acrylonitrile butadiene styrene (ABS)
- styrene butadiene rubber (SBR)
- unsaturated polyester resins
- styrene butadiene latices
As a result, nearly everyone encounters styrene-based products in some form every day. Materials made with styrene can be found in many familiar items including food and drink containers, packaging, rubber tyres, building insulation, carpet backing, computers and reinforced fiberglass composites such as boat hulls, surfboards and kitchen countertops.
