PBAT is a thermoplastic biodegradable plastic whose full name is Polybutylene Adipate Terephthalate (copolymer of polybutylene terephthalate and polybutylene adipate). This material combines the properties of polybutylene adipate (PBA) and polybutylene terephthalate (PBT), so it has good ductility and elongation at break, as well as good heat resistance and impact resistance.
The raw materials include 1, 4-butanediol (BDO), adipic acid (AA), and terephthalic acid (PTA). It has a semi-crystalline structure with a melting point of about 130 degrees Celsius. Due to its biodegradable properties, PBAT is often used in the manufacture of disposable items to reduce environmental impact.
