Polybutylene adipate terephthalate (PBAT)

Polybutylene adipate terephthalate

Polybutylene adipate terepthalate (PBAT) is a random copolymer (themoplast) of a copolyester of adipic acid, 1,4-butanediol and terephthalic acid (from dimethyl terephthalate). <font 10.5pt/inherit;;inherit;;inherit>Among the biodegradable plastics, PBAT has one of the highest shares in global production (European-Bioplastics, 2022). It is mainly used as foil for packaging and in agriculture as it has similar properties like low-density PE. The co-aliphatic-aromatic polyester is produced by a random polymerization of terephthalic acid and adipic acid with 1,4-butanediol. Its aliphatic components make it easier to be biodegraded by microbial enzymes belonging to the group of carboxylesterases, lipases and cutinases.</font> The polymer can also be found under the names poly(butylene adipate-co-terephthalate) and polybutyrate-adipate-terephthalat or simply polybutyrate.
