      PBAT Polybutylene Adipate Terephthalate
          Publish time 2021-07-07 13:45    

      PBAT is a kind of thermoplastic biodegradable plastics, which is a copolymer of butylene adipate and butylene terephthalate.Withcharacteristics of PBA and PBT, it has good ductility and elongation atbreak, good heat resistance and impact performance, and excellentbiodegradability.Through the metabolism of microorganisms or

      enzymes, it can be decomposed into oxygen-containing compounds suchas carbon dioxide and water in a nature environment. lt is known as environment-friendly polyester.

      Application

      lt is mainly used in biodegradable shopping bags, express bags, packaging films, agricultural films, 3D printing, disposable tableware, disposable medical supplies, etc
