Key Properties
Styrene monomer is a colorless to pale yellow liquid that serves as a fundamental building block in the production of various polymers. It is one of the most significant industrial monomers, primarily utilized in the synthesis of polystyrene, a widely used plastic, and synthetic rubber. Styrene is known for its characteristic sweet odor and is classified as a volatile organic compound (VOC). Due to its importance in the polymer industry, styrene is produced in large quantities and is essential for the manufacture of products ranging from packaging materials to automotive components.
Also known as Vinylbenzene, Phenylethylene.

- Substance
Styrene is a colorless to pale yellow liquid with a density of 0.906 g/mL at 20°C. It has a boiling point of approximately 145°C and a melting point of -30.6°C. The vapor pressure of styrene at 20°C is about 6.7 mmHg, indicating its volatility. Styrene is soluble in organic solvents such as ethanol and ether but has limited solubility in water. It has a characteristic sweet odor, with an odor threshold of approximately 0.3 ppm, making it detectable at low concentrations.
