PBS (poly (butylene succinate)) is a biodegradable plastic, widely used in packaging, agriculture, medical and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of PBS mainly include the following aspects:

upstream raw materials:

1. Succinic acid: Succinic acid is one of the main raw materials of PBS, and its chemical name is succinic acid, which is a dicarboxylic acid. Succinic acid can be produced by microbial fermentation or chemical synthesis.
2. Butanediol: Butanediol is another major raw material of PBS and is a glycol. Butanediol can be prepared by the addition reaction of petrochemical raw materials ethylene glycol and butyraldehyde.

downstream products:

1. Packaging material: PBS, as a biodegradable plastic, can be used to produce packaging materials such as packaging bags, lunch boxes, and bottle caps. It has the advantages of environmental protection and degradation.
2. Agricultural film: PBS can be made into agricultural film, used for crop cover, can improve the yield and quality of crops, at the same time has degradability, will not cause pollution to the environment.
3. Medical equipment: PBS is biocompatible and biodegradable, so it can be used to produce medical equipment, such as disposable syringes, infusion sets, etc.
4. Other fields: In addition to the above fields, PBS can also be used to produce other chemical products such as fibers and engineering plastics.

In summary, the upstream and downstream related products of PBS cover many fields and have a wide range of applications. With the improvement of people's awareness of environmental protection and the demand for sustainable development, PBS as a biodegradable plastic will be more and more attention, and its application field will continue to expand.
