DBP (dibutyl phthalate) is a common chemical raw material, widely used in plastics, rubber, paint, coatings and other fields. In the upstream and downstream related products of DBP, the following aspects are mainly involved:

1. Upstream raw material

The upstream raw materials of DBP are mainly phthalic anhydride and n-butanol. Phthalic anhydride is an important organic chemical raw material, mainly used in the production of plasticizers, stabilizers, dyes and so on. Butanol is used as a solvent, plasticizer and manufacturing butyl aldehyde, butyric acid and other compounds of raw materials.

2. Downstream product

DBP as a plasticizer, its main function is to increase the plasticity, flexibility and ductility of polymer materials. Therefore, DBP's downstream products mainly involve various plastic and rubber products, such as PVC wire and cable, artificial leather, rubber shoes, etc.

In addition, DBP can also be used to produce paints, coatings and other coating products to improve the flexibility and durability of coatings. At the same time, DBP can also be used to manufacture some spices, pharmaceutical intermediates and other products.

In short, DBP as an important chemical production raw materials, its upstream and downstream related products are extensive, involving many fields, such as plastics, rubber, paint, coatings and so on.
