In the field of chemical production raw materials, the upstream and downstream related products of other additives are very extensive. The following are some common upstream and downstream related products:

1. Upstream products:
* Crude oil: Many chemical raw materials are derived from petroleum, such as olefins, aromatics and other basic chemical raw materials.
* Natural gas: Natural gas is mainly used for the production of synthetic ammonia, methanol and other chemicals.
* Coal: Coal is an important source of basic chemical raw materials such as coke and syngas.
* salt, limestone, sulfur and other inorganic minerals: these minerals are the production of fertilizer, chlor-alkali and other basic chemical raw materials.

2. Downstream products:
* Plastics: Many additives are used in plastic production, such as plasticizers, antioxidants, light stabilizers, etc.
* Rubber: Rubber additives include vulcanizing agents, accelerators, antioxidants, etc.
* Coating: Coating additives include leveling agent, defoamer, dispersant, etc.
* adhesive: additives can improve the adhesive bonding strength, weather resistance and other properties.
* textile finishing agent: textile finishing agent including softener, antistatic agent, waterproof agent, etc.

specific to other additives, its upstream and downstream related products will be more specific and special. For example, the upstream raw materials of lubricating oil additives may include base oils, thickeners, etc., while the downstream products are various types of lubricating oils; the upstream raw materials of fuel additives may include organic compounds such as alcohols and esters, while the downstream products are various types of fuels.

In short, the chemical production of raw materials in the field of additives upstream and downstream related products are very extensive, specific products need to be determined according to the specific types and uses of additives.
