Dibutyl fumarate (DBM) is a widely used plasticizer, mainly used in plastic and rubber products to increase their flexibility, ductility and plasticity. In the field of chemical production raw materials, the upstream and downstream related products of dibutyl fumarate mainly include the following aspects:

upstream products:

1. Fumaric acid: Fumaric acid is one of the main raw materials for the production of dibutyl fumarate. It is an unsaturated fatty acid, which can be produced by oxidation of butadiene in petroleum cracking products.
2. Butanol: Butanol is another major raw material for the production of dibutyl fumarate, which is an alcohol compound that can be produced by hydration of butenes in petroleum cracking products.

downstream products:

1. Plastic: Dibutyl fumarate as a plasticizer can be widely used in various plastic products, such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), etc., to improve its flexibility, ductility and plasticity.
2. Rubber: Dibutyl fumarate can also be used in rubber products, such as tires, hoses, tapes, etc., to increase its elasticity, low temperature resistance and flex resistance.
3. coatings: dibutyl fumarate can be used as additives in coatings to improve the leveling, toughness and weather resistance of coatings.
4. Ink: Dibutyl fumarate can also be used in ink to improve the fluidity and printing performance of ink.

In short, dibutyl fumarate has a wide range of upstream and downstream related products in the field of chemical production raw materials, which plays an important role in promoting the development of plastics, rubber, coatings and inks.
