In the field of chemical production raw materials, DOP (dioctyl phthalate) is a common plasticizer, which is widely used in plastics, rubber, paint, coatings and other fields. The upstream and downstream related products of DOP mainly include the following aspects:

upstream products:

1. Phthalic anhydride: Phthalic anhydride is one of the main raw materials of DOP, which is used to produce phthalate plasticizers.
2. Octanol: Octanol is another major raw material for DOP, which reacts with phthalic anhydride to produce DOP.

downstream products:

1. PVC products: DOP as the main plasticizer of PVC products, can make PVC products more soft, flexible, improve the processing performance and service life of products.
2. Rubber products: DOP can be used in rubber products to increase the flexibility, elasticity and processing properties of rubber.
3. Paint: DOP can be used as an additive in paint coatings to improve the leveling, gloss and adhesion of coatings.
4. Textiles: DOP can be used for coating finishing of textiles to improve the water resistance, breathability and elasticity of fabrics.

To sum up, DOP's upstream and downstream related products cover many fields, such as plastics, rubber, paint coatings, textiles, etc. These products are interrelated with DOP and together constitute a complete chemical industry chain.
