Styrene is an important organic chemical raw material, which is widely used in the production of various plastics, resins, synthetic rubber and other products. As a driving material for styrene, its upstream and downstream related products are also very rich. The following are some of the main upstream and downstream related products:

upstream products:

1. Ethylene: The production of styrene is mainly made from ethylene as raw material through the alkylation reaction of benzene and ethylene.

2. Benzene: Benzene is another important raw material in the production of styrene, which is formed by reacting with ethylene.

downstream products:

1. Polystyrene (PS): homopolymer of styrene, which is a transparent, hard and brittle plastic material, widely used in packaging, electrical appliances, construction and other fields.

2. Acrylonitrile-butadiene-styrene copolymer (ABS): A copolymer of styrene, acrylonitrile and butadiene, which has excellent impact resistance, heat resistance, chemical resistance, etc., and is used in the manufacture of automobiles, electrical appliances, toys, etc.

3. Styrene-acrylonitrile copolymer (SAN): copolymer of styrene and acrylonitrile, has excellent heat resistance, chemical resistance, transparency, etc., used in the manufacture of tableware, medical equipment, transparent products, etc.

4. Ion exchange resin: Styrene can be used to produce ion exchange resin, which is widely used in water treatment, chemical industry, metallurgy and other fields.

In short, styrene is an important organic chemical raw material, and its upstream and downstream related products are very extensive, involving many fields, such as plastics, resins, synthetic rubber, ion exchange resins, etc.
