As an important chemical raw material, styrene is widely used in plastics, rubber, synthetic fiber and other fields. Its upstream and downstream related products are numerous, and some of the main upstream and downstream products will be described in detail below. Upstream products of

:

1. Ethylene: Ethylene is one of the main raw materials of styrene. Styrene is produced by alkylation of ethylene and benzene.

2. Benzene: Benzene is another main raw material of styrene, which is formed by alkylation reaction with ethylene.

downstream products:

1. Polystyrene (PS): Styrene is generated by polymerization. Polystyrene is a common plastic material with excellent insulation, corrosion resistance and processing performance. It is widely used in electronics, Home appliances, construction, packaging and other industries.

2. acrylonitrile-butadiene-styrene copolymer (ABS): styrene and acrylonitrile, butadiene copolymer to produce ABS resin, a comprehensive performance of excellent engineering plastics, with high strength, heat resistance, cold resistance, chemical resistance and electrical insulation, widely used in automobiles, home appliances, electronic appliances, construction and other fields.

3. Styrene-acrylonitrile copolymer (SAN): Styrene and acrylonitrile copolymer SAN resin, with excellent heat resistance, chemical resistance and electrical insulation, can be used in the production of kitchen utensils, medical equipment, electrical parts, etc.

4. Ion exchange resin: Styrene can be used to prepare ion exchange resin, a polymer material with ion exchange function, which is widely used in water treatment, chemical industry, metallurgy and other fields.

5. synthetic rubber: styrene can be used as one of the monomers of synthetic rubber, and other monomers to produce a variety of properties of synthetic rubber, such as styrene butadiene rubber, neoprene, etc., widely used in tires, hose, tape and other fields.

In short, there are many upstream and downstream related products of styrene, involving a wide range of fields, which plays an important role in promoting the development of the chemical industry.
