Plasticizer is an additive widely used in chemical production, mainly used to increase the plasticity, flexibility and ductility of plastics. In the field of chemical production raw materials, the upstream and downstream related products of plasticizers mainly include the following aspects:

upstream products:

1. Phthalic anhydride: Phthalic anhydride is one of the main raw materials for the production of plasticizers, which can be used to produce common plasticizers such as dioctyl phthalate (DOP).
2. Octanol: Octanol is another common plasticizer production raw material, and phthalic anhydride reaction can generate dioctyl phthalate (DOP) and other plasticizers.

downstream products:

1. Plastic products: The main application areas of plasticizers are plastic products, such as PVC pipes, films, and artificial leather. Adding plasticizers can reduce the glass transition temperature of plastic products, increase their flexibility and plasticity, and make them easier to process and use.
2. Rubber products: Plasticizers can also be used in rubber products, which can increase the flexibility, ductility and plasticity of rubber, and improve its processing performance and use performance.
3. coatings and adhesives: Plasticizers can also be used in coatings and adhesives to adjust their viscosity and fluidity and improve their construction performance and use performance.

In short, plasticizers play an important role in the field of chemical production raw materials, and their upstream and downstream related products are extensive, involving many fields, such as plastic products, rubber products, coatings and adhesives.
