Styrene Monomer

About Styrene Monomer

Styrene Monomer (chemical formula: CH) is a clear, colorless to slightly yellow oily liquid with a characteristic sweet odor. It is an aromatic hydrocarbon derived primarily from petroleum-based feedstocks such as ethylbenzene. Styrene is highly reactive due to its vinyl group, making it a key building block in polymer chemistry.

It readily undergoes polymerization to form a wide range of plastics, resins, rubbers, and latex materials. Due to its versatility, Styrene Monomer is a fundamental raw material in the petrochemical and plastics industries.
