Polybutylene succinate adipate (PBSA) resin is a type of polyester resin,
Nature:
Has excellent physical and chemical properties. Its main properties include low temperature resistance, wear resistance, chemical corrosion resistance, UV resistance, etc.
Usage:
1. Used in plastic processing, packaging, fiber, medical devices, electronics and other fields.
2. It can be made into various injection molded parts, blow molded parts, thin films, sheets and other products, with excellent conductivity, wear resistance, and flame retardancy, and is widely used in the field of electronic and electrical appliances.
Method:
Mainly obtained by condensation reaction between polymer and adipic acid ester. The reaction takes place at high temperatures, and the resulting resin has a high molecular weight and stable structure.
Security information:
Good ventilation conditions should be maintained during the processing to avoid the generation of harmful gases. At the same time, safety measures such as moisture prevention, fire prevention, and shock prevention should also be taken during storage and transportation.

Sharp tools such as iron hooks shall not be used or thrown during transportation and loading and unloading. The means of transport shall be kept clean, dry and provided with sheds or tarpaulins. During transportation, it shall not be mixed with sand, crushed metal, coal and glass, shall not be mixed with toxic and corrosive or flammable materials, and shall not be exposed to the sun or rain.
polysuccinic acid-butylene adipate resin should be stored in a cool, ventilated, dry, clean and well-protected warehouse. When storing, it should be kept away from heat sources and prevent direct sunlight. polysuccinic acid-butylene adipate resin should not be piled up in the open air. the storage period should be stipulated. generally, it should not exceed 12 months from the date of production. after opening, it should be used as soon as possible
group batch
Poly (succinic acid-adipic acid butylene ester resin with the same production line, the same raw material, the same process produced by the same brand of product group batch can also be according to a certain production cycle or storage silo for a batch of products. Products are inspected and accepted in batches
Sampling
Poly (succinic acid-butylene adipate) resin can be sampled at the sampling port of the silo, or a specific sampling scheme can be determined according to the actual situation such as the production cycle. the sampling of packaged products should be carried out in accordance with GB/T2547-2008 regulations.
factory inspection
The factory inspection of polysuccinic acid-butylene adipate resin should at least include appearance, melt mass flow rate, carboxyl content and water content
type inspection
Type inspection is all items, type inspection shall be carried out under the following circumstances a) when it is first put into production B) under normal circumstances, type inspection shall be carried out at least once a year
decision rules
When one of the inspection items in the inspection results is unqualified, double the amount of samples from the same batch of products shall be taken again for re-inspection of the unqualified items to be subject to the re-inspection results. If there is one unqualified item in the re-inspection, the whole batch will be judged as unqualified. 6 marks. The outer packaging of polysuccinic acid-butylene adipate resin products should have obvious marks. The contents of the logo shall include: melt quality flow rate, trademark, name and address of the manufacturer, standard number, product name, brand, production date, batch number and net content, etc. 7 Packaging, transportation and storage 7.1 packaging polysuccinic acid-butylene adipate resin can be packaged in woven bags lined with aluminum foil bags or other sealed moisture-proof packaging forms. Packaging materials shall ensure no contamination and leakage during transportation, stacking and storage
