About Styrene
Styrene[‘stī-,rēn] is a clear, colorless liquid that is synthesized for commercial use from petroleum and natural gas by-products. Styrene also occurs naturally in the environment and is an inherent component in small concentrations of many commonly-consumed foods and beverages, such as coffee, strawberries, and cinnamon.
