AS resin (Acrylonitrile-Styrene Resin) is a transparent, high hardness thermoplastic, with excellent heat resistance, chemical resistance and electrical insulation, is widely used in home appliances, automobiles, construction, electronic appliances, medical equipment and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of AS resin mainly include the following aspects:

upstream products:

1. Acrylonitrile (Acrylonitrile): Acrylonitrile is one of the main raw materials of AS resin, which is used to polymerize with styrene monomer to form AS resin. The main production methods of acrylonitrile are cyanidation and propylene ammoxidation.
2. Styrene (Styrene): Styrene is also one of the main raw materials of AS resin, and acrylonitrile monomer polymerization to form AS resin. Styrene is produced primarily by the reaction of ethylene with benzene.

downstream products:

1. Household appliances: AS resin has excellent heat resistance, chemical resistance and electrical insulation, so it is widely used in the manufacture of household appliances, such as refrigerators, washing machines, air conditioners, etc.
2. Automotive industry: AS resin can be used to manufacture automotive lamps, dashboards, interior decoration parts, etc., with high transparency, strong impact resistance, and good heat resistance.
3. Construction field: AS resin can be used to make building materials, such as windows, door handles, pipes, etc., with excellent weather resistance and chemical resistance.
4. Electrical and electronic appliances: AS resin can be used in the manufacture of electrical and electronic housings, parts, etc., with high insulation, heat resistance, impact resistance and other advantages.
5. Medical devices: AS resin has excellent chemical resistance and transparency, so it is widely used in the manufacture of medical devices, such as syringes, infusion sets, etc.

In summary, AS resin has a wide range of upstream and downstream related products in the field of chemical production raw materials, and its application fields involve home appliances, automobiles, construction, electronic appliances, medical devices and other fields.
