PBAT bụ plastik biodegradad nke nwere ike imebi thermoplastic. Ọ bụ copolymer nke butanediol adipate na butanediol terephthalate. Ọ nwere njirimara PBA na PBT. Ọ nwere ọ bụghị naanị ezigbo ductility na elongation na nkwụsịtụ, kamakwa ezigbo nguzogide okpomọkụ na mmetụta mmetụta; Na mgbakwunye, ọ nwekwara ezigbo biodegradability. Ọ bụ otu n'ime ihe ndị na-emepụta ihe na-arụ ọrụ nke ọma na nyocha nke plastik na-emepụta ihe na otu n'ime ihe kachasị mma na ahịa.
PBAT bụ ọkara kristal polymer. The crystallization okpomọkụ na-emekarị gburugburu 110 ℃, agbaze ebe bụ banyere 130 ℃, na njupụta bụ n'etiti 1.18g/ml na 1.3g/ml. The crystallinity nke PBAT bụ banyere 30%, na n'ikpere mmiri ike karịrị 85. PBAT bụ a copolymer nke aliphatic na aromatic polyesters, nke na-agwakọta magburu onwe mbibi Njirimara nke aliphatic polyesters na ezi n'ibu Njirimara nke aromatic polyesters. Ọrụ nhazi nke PBAT dị nnọọ ka nke LDPE. Enwere ike iji akụrụngwa nhazi LDPE maka ịfụ ihe nkiri.
