Aromatic plasticizers play an important role in the field of raw materials for chemical production, and their upstream and downstream related products are extensive. The main upstream and downstream related products of aromatic plasticizers will be described in detail below.

upstream related products:

1. Benzene: Benzene is one of the main raw materials of aromatic plasticizers. A variety of aromatic plasticizers can be synthesized through benzene derivatives. The production of benzene mainly comes from petrochemical and coal chemical industries.
2. Toluene: Toluene is another common aromatic plasticizer raw material, through the oxidation of toluene, alkylation and other reactions can be prepared a variety of plasticizers. Toluene production is also mainly from the petrochemical industry.
3. Ethylene: Ethylene is an important chemical raw material. Plastic materials such as polyethylene and polyvinyl chloride can be prepared by the polymerization of ethylene. These materials need to be added with plasticizers to improve their flexibility during the production process. Ethylene production is mainly from the petrochemical industry.

downstream related products:

1. Plastic products: The main application areas of aromatic plasticizers are the plastic products industry, such as polyvinyl chloride, polyethylene, polypropylene, etc. The addition of plasticizers can reduce the glass transition temperature of plastics and improve their flexibility and processability.
2. Rubber products: Rubber products also need to add plasticizers in the production process to improve their elasticity and processability. Aromatic plasticizers are also widely used in rubber products.
3. Coatings and adhesives: Aromatic plasticizers can also be used in coatings and adhesives to improve their fluidity and flexibility and improve the performance of the coating film.

In short, the upstream and downstream related products of aromatic plasticizers are very extensive, involving petrochemical, coal chemical, plastic products, rubber products, coatings and adhesives and other fields. With the continuous development of the chemical industry, the application field of aromatic plasticizers will continue to expand.
