The main purpose

The most important use is as a monomer for synthetic rubber and plastics to produce styrene butadiene rubber, polystyrene, and foamed polystyrene; it is also used to copolymerize with other monomers to produce engineering plastics for many different purposes. Such as copolymerization with acrylonitrile and butadiene to make ABS resin, which is widely used in various household appliances and industries; SAN made by copolymerization with acrylonitrile is an impact-resistant and bright color resin; made by copolymerization with butadiene SBS is a kind of thermoplastic rubber, which is widely used as modifier of polyvinyl chloride and polypropylene.

Styrene is mainly used in the production of styrene series resins and styrene butadiene rubber. It is also one of the raw materials for the production of ion exchange resins and pharmaceuticals. In addition, styrene can also be used in industries such as pharmaceuticals, dyes, pesticides, and mineral processing.
