PBAT ke polasetiki e bolang ka thermoplastic. Ke copolymer ea butanediol adipate le butanediol terephthalate. E na le litšobotsi tsa PBA le PBT. Ha e na feela ho ductility e ntle le ho lelefala ha e robeha, empa hape e na le ho hanyetsa mocheso hantle le thepa ea tšusumetso; Ho phaella moo, e boetse e na le ho bola ho babatsehang. Ke e 'ngoe ea thepa e bolang ka ho fetisisa lipatlisisong tsa polasetiki e bolang 'me ke e 'ngoe ea thepa e bolang ka ho fetisisa' marakeng.
PBAT ke polymer e semicrystalline. Mocheso oa kristale hangata o ka ba 110 ℃, ntlha ea ho qhibiliha e ka ba 130 ℃, 'me bongata bo pakeng tsa 1.18g/ml le 1.3g/ml. Kristalinity ea PBAT e ka ba 30%, 'me boima ba lebōpo bo feta 85. PBAT ke copolymer ea li-polyester tsa aliphatic le aromatic, e kopanyang litšobotsi tse ntle tsa ho senyeha ha li-polyester tsa aliphatic le litšobotsi tse ntle tsa mechini tsa li-polyester tse nkhang hamonate. Tshebetso ea ts'ebetso ea PBAT e tšoana haholo le ea LDPE. Lisebelisoa tsa ts'ebetso ea LDPE li ka sebelisoa bakeng sa ho phunya filimi.
