PBS
Polybutylene succinate
PBS is a degradable and environment-friendly material. Lanshantun River PBS has excellent mechanical properties, close to PP and ABS plastics; The heat resistance is good, the thermal deformation temperature is close to 100 ℃, and the service temperature after modification can exceed 100 ℃. PBS is widely used in packaging (including food packaging, cosmetic bottles, drug bottles), tableware, disposable medical supplies, agricultural film, pesticide and fertilizer slow-release materials, biomedical polymer materials and other fields. It can not only meet the demand through petrochemical products, but also produce natural renewable crop products such as cellulose, dairy by-products, glucose, fructose and lactose through biological fermentation, so as to realize green circular production from nature and return to nature.

Storage：
Temperatures during transportation and storage should not exceed 70 oC. Keep resin in dry and ventilated warehouse to prevent moisture. Avoid contacting with soil, water and sludge, and no exposure to direct sunlight and extreme temperature.The maximum shelf life is 2 years in ambient temperature of 23oC if the package has been tightly sealed. Drying：
It is recommended to pre-dry the material prior to getting the best processing performance. If the moisture of the resin is less than 0.05% pre-drying may not be needed. Typical drying conditions：2 hours at 80oC (175oF).
