Definition of styrene: Styrene is a compound formed by replacing a hydrogen atom of ethylene with benzene. The electrons of vinyl and benzene ring will have resonance effect. Referred to as SM. It is an important basic raw material for the petrochemical industry.
The use of vinyl: mainly used in the production of styrene series resin and styrene-butadiene rubber, but also one of the raw materials for the production of ion exchange resins and pharmaceutical products. In addition, styrene can also be used in pharmaceutical, dye, pesticide and mineral processing industries. The output of styrene series resin ranks third in the world in synthetic resin, second only to PE and PVC.
Polystyrene (PS), a homopolymer of styrene, is one of the five general-purpose thermoplastic synthetic resins. It is widely used in the three major fields of injection molding products, extrusion products and foam products. Demand development has grown vigorously in recent years.
ABS resin made by copolymerization of styrene, butadiene and acrylonitrile is the largest bulk thermoplastic engineering plastic. It is the most developed and changed variety of styrene series resins. It is used in electronic appliances, instrumentation, automobile manufacturing, home appliances, toys , Building materials industry and other fields have been widely used. China has become one of the world's largest producers and consumer markets of ABS.
Styrene-butadiene rubber is a copolymer of butadiene and styrene. It is the largest general-purpose synthetic rubber variety and one of the first industrialized rubbers. The annual consumption of styrene butadiene rubber accounts for the first place in synthetic rubber.
Acrylonitrile-styrene binary copolymer (SAN), unsaturated resin (UPr), styrene-butadiene rubber (SBR), styrene-butadiene latex (SBL), thermoplastic styrene-butadiene rubber (SBS) and other products that can be produced from styrene It can be said that styrene is one of the most important monomers in the chemical industry
