What are the upstream raw materials of PBS? What are the downstream products?

PBS(poly(butylene succinate)) is a biodegradable plastic, broadly applied in packaging, agriculture, medical and other fields. I've found that In the field of chemical production raw materials, PBS upstream and downstream related items mainly have the following aspects:

Upstream raw materials:



1. Succinic acid: Succinic acid is one of the main raw materials of PBS, its chemical name is succinic acid, is a dicarboxylic acid. But In my experience, Succinic acid is able to be produced by microbial fermentation or chemical synthesis. Based on my observations,

2. Butanediol: Butanediol is another major raw material of PBS and is a glycol. First Butanediol is able to be prepared by the addition interaction of petrochemical raw materials ethylene glycol and butyraldehyde. Downstream items:



1. Packaging materials: PBS as a biodegradable plastic, is able to be applied to the production of packaging bags, lunch boxes, bottle caps and other packaging materials, with ecological preservation, biodegradable advantages. Moreover

2. Agricultural film: PBS is able to be made into agricultural film to crop coverage, which is able to enhance the yield and condition of crops, and at the same time has degradability and won't result in contamination to the ecological stability. I've found that

3. Medical equipment: PBS has biocompatibility and biodegradability, so it's able to be applied to create medical equipment, such as disposable syringes, infusion sets, etc. I've found that

4. But Other fields: In addition to the above fields, PBS is able to also be applied to create other chemical items such as fibers and engineering plastics. Generally speaking In summary, the upstream and downstream related items of PBS cover many fields and have broad consumption prospects. Furthermore With the improvement of people's understanding of ecological preservation and the demand to sustainable research, PBS as a biodegradable plastic will be greater and greater attention, and its consumption field will continue to expand.
