PBAT ke lipolasetiki tsa thermoplastic biodegradable. Ke copolymer ea butanediol adipate le butanediol terephthalate. E na le litšobotsi tsa PBA le PBT. Ha e na feela ductility e ntle le elongation nakong ea khefu, empa hape e na le ho hanyetsa mocheso o motle le thepa ea tšusumetso; Ho feta moo, e boetse e na le biodegradability e ntle haholo. Ke e 'ngoe ea lisebelisoa tse sebetsang ka ho fetesisa tse ka senyehang ka ho fetesisa liphuputsong tsa lipolasetiki tse senyehang le e 'ngoe ea lisebelisoa tse senyehang ka ho fetisisa 'marakeng.
PBAT ke polymer ea semi crystalline. Thempereichara ea crystallization hangata e ka ba 110 ℃, sebaka se qhibilihang se ka bang 130 ℃, 'me boima bo pakeng tsa 1.18g/ml le 1.3g/ml. The crystallinity ea PBAT ke hoo e ka bang 30%, 'me lebopo le thata ho feta 85. PBAT ke copolymer ea polyester ea aliphatic le e nkhang hamonate, e kopanyang thepa e babatsehang ea ho senyeha ha li-polyester tsa aliphatic le thepa e ntle ea mechine ea li-polyester tse nkhang hamonate. Ts'ebetso ea ts'ebetso ea PBAT e ts'oana haholo le ea LDPE. Lisebelisoa tsa ts'ebetso ea LDPE li ka sebelisoa ho foka filimi.
