PBS is a typical aliphatic polyester, and also a new biodegradable polymer material. The main raw materials for PBS synthesis, 1,4-succinic acid and 1,4-butanediol, can be obtained not only by petrochemical route, but also by coal chemical route and biological fermentation route, so it has more environmental significance and economic value.
Fully biodegradable.
Good melting point and high performance, can replace general-purpose polyethylene or polypropylene and enter the field of general-purpose plastics.
It is non-toxic, harmless and has good biocompatibility.

1. Packaging materials, such as garbage bags, food bags, various bottles and labels.
2. Agricultural and forestry supplies, agricultural films, all kinds of planting utensils, vegetation nets, pesticides and fertilizer slow-release materials.
3. Daily sundries, a company takes PBS as the main raw material, and fills talcum powder and calcium carbonate to make various shaped products.
4, Medical aspects, disposable medical supplies, biomedical polymer materials, drug slow-release carrier matrix.
The products can be packed in woven bags lined with aluminum foil bags or other sealed moisture-proof packaging forms. Packaging materials should ensure that there is no contamination or leakage during transportation, yardage and storage.
The product should be stored in a cool, ventilated, dry, clean warehouse with good fire fighting facilities, and when stored, it should be kept away from heat sources, and prevented from direct sunlight, and should not be stacked in the open air.
