Blocked classification antioxidants have an important position in the field of chemical production raw materials, and their upstream and downstream related products are extensive. The following are some common upstream and downstream related products of hindered antioxidants:

upstream related products:

1. Phenol: Phenol is an important raw material for hindered phenolic antioxidants and can be used to produce a variety of hindered phenolic antioxidants, such as BHT (2,6-di-tert-butyl-p-cresol).
2. Methanol: Methanol can be used as a solvent and raw material in the production of hindered phenolic antioxidants to participate in the synthesis of some specific hindered phenolic antioxidants.
3. Butanone: As a solvent, butanone plays an important role in the production of hindered phenolic antioxidants and helps to improve the purity and quality of the product.

Downstream Related Products:

1. Plastics: Blocked phenolic antioxidants are widely used in the plastics industry, which can effectively extend the service life of plastic products and improve their thermal stability and oxidation resistance. Common plastic products include polyethylene, polypropylene, polyvinyl chloride, etc.
2. rubber: hindered phenolic antioxidants can improve the heat resistance, oxidation resistance and aging resistance of rubber products, and prolong the service life of rubber products. Common rubber products include natural rubber, synthetic rubber, etc.
3. Oil: Hindered phenolic antioxidants can be used in oil products to improve their antioxidant properties and extend the storage period of oil. Common oil products include edible oil, industrial oil, etc.

In short, the upstream and downstream related products of hindered phenolic antioxidants are very extensive, involving many fields, such as plastics, rubber, grease, etc. The quality and performance of these related products are affected by the hindered phenolic antioxidants, so it is of great significance to select the appropriate hindered phenolic antioxidants to improve the quality and performance of the products.
