Styrene is an important industrial chemical raw material, chemical formula C8H8, is a conjugated diene composed of benzene ring and ethylene monomer. In industrial production, styrene is mainly obtained by polymerizing ethylene and benzene with a catalyst. Styrene is a colorless and transparent liquid that is volatile at room temperature and has a unique aromatic and pungent odor. The physical and chemical properties of

styrene mainly depend on its molecular structure. It is a conjugated diene, so it has good stability and is not easily oxidized or decomposed. The molecule of styrene contains aromatic groups, which makes it have high polarity and chemical activity. For example, styrene can undergo addition reactions, alkylation reactions, oxidation reactions, etc. with other molecules to form a large number of organic compounds.

styrene is an important industrial raw material, widely used in machinery manufacturing, building materials, daily necessities, medicine, cosmetics and other fields. Among them, the most important application fields include polystyrene (PS), acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC) and styrene rubber.

polystyrene is an important derivative of styrene, is one of the earliest application of plastic, with excellent electrical insulation properties, transparency and mechanical strength. Polystyrene, also known as PS plastic, can be made into various shapes of products, such as plastic containers, tableware, electrical appliances and so on. In addition, polystyrene can also be processed into foam, used as packaging materials, sound insulation materials and insulation materials. Styrene is also used to make ABS (acrylonitrile-butadiene-styrene copolymer), which is a high-performance plastic with excellent impact resistance and heat resistance. It is widely used in auto parts, electrical housings, Toys and other fields.

styrene can also be used to manufacture polycarbonate (PC), which is a colorless transparent plastic with high strength, high heat resistance, high impact resistance and excellent optical properties, and is widely used in optical devices, electrical housings, building boards and other fields.

In addition to polymer materials, styrene can also be made into styrene rubber, which has excellent oil resistance, heat resistance and corrosion resistance, and is widely used in tires, seals, pipes and other fields.
