PBAT ni plastiki ya biopgradable ya plastike.Ni copolymer ya butanediol adipate na butanediol terephthalate.Ifite ibiranga PBA na PBT.Ntabwo ifite ihindagurika ryiza no kurambura gusa kuruhuka, ahubwo ifite imbaraga zo kurwanya ubushyuhe ningaruka;Mubyongeyeho, ifite kandi ibinyabuzima byiza cyane.Nibimwe mubikoresho bikora biodegradable cyane mubushakashatsi bwa plastiki ibora kandi kimwe mubikoresho byangirika ku isoko.
PBAT ni polymer ya kimwe cya kabiri.Ubushyuhe bwo korohereza ubukonje buri hafi 110 ℃, aho gushonga ni 130 ℃, n'ubucucike buri hagati ya 1.18g / ml na 1.3g / ml.Crystallinity ya PBAT igera kuri 30%, kandi ubukana bwinkombe burenga 85. PBAT ni copolymer ya alifatique na aromatic polyester, ikomatanya ibintu byiza byo gutesha agaciro polifester ya alifatique hamwe nuburyo bwiza bwubukanishi bwa poloteri nziza.Imikorere yo gutunganya PBAT irasa cyane niyi LDPE.Ibikoresho byo gutunganya LDPE birashobora gukoreshwa mugukubita firime.
