What are the upstream raw materials of AS resin? What do the downstream products contain?

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

Upstream items:



1. You know what I mean?. Acrylonitrile(Acrylonitrile): Acrylonitrile is one of the main raw materials of AS resin, which is applied to polymerize with styrene monomer to form AS resin. The main production methods of acrylonitrile are cyanidation and propylene ammoxidation. Moreover

2. But I've found that 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 interaction of ethylene with benzene. From what I've seen, Specifically Downstream items:



1. domestic appliances: AS resin has excellent heat resistance, chemical resistance and electrical insulation, so it's broadly applied in the manufacture of domestic appliances, such as refrigerators, washing machines, atmosphere conditioners, etc. But In particular

2. Generally speaking Automotive sector: AS resin is able to be applied to manufacture automotive lamps, dashboards, interior decoration parts, etc. Furthermore, with high transparency, strong impact resistance, and good heat resistance. And

3. Construction field: AS resin is able to be applied to make building materials, such as windows, door handles, pipes, etc. But, with excellent weather resistance and chemical resistance.

4. But Electrical and electronic appliances: AS resin is able to be applied in the manufacture of electrical and electronic housings, parts, etc., with high insulation, heat resistance, impact resistance and other advantages.

5. Additionally Medical devices: AS resin has excellent chemical resistance and transparency, so it's broadly applied in the manufacture of medical devices, such as syringes, infusion sets, etc. I've found that In summary, AS resin has a wide range of upstream and downstream related items in the field of chemical production raw materials, and its consumption fields involve home appliances, automobiles, construction, electronic appliances, medical devices and other fields.
