ʻO ka PBAT he mau mea hiki ke hoʻoheheʻe ʻia ka thermoplastic. He copolymer o butanediol adipate a me butanediol terephthalate. Loaʻa iā ia nā hiʻohiʻona o PBA a me PBT. ʻAʻole wale ka ductility maikaʻi a me ka elongation i ka wā hoʻomaha, akā maikaʻi nō hoʻi ke kūpaʻa wela a me nā waiwai hopena; Eia kekahi, loaʻa iā ia ka biodegradability maikaʻi loa. ʻO ia kekahi o nā mea biodegradable ikaika loa i ka noiʻi ʻana i nā plastic biodegradable a me kekahi o nā mea hoʻoheheʻe maikaʻi loa i ka mākeke.
ʻO ka PBAT kahi polimer semi crystalline. ʻO ka maʻamau o ka crystallization ma kahi o 110 ℃, ʻo ka helu heheʻe ma kahi o 130 ℃, a ʻo ka nui ma waena o 1.18g/ml a me 1.3g/ml. ʻO ka crystallinity o PBAT ma kahi o 30%, a ʻoi aku ka paʻakikī o ke kahakai ma mua o 85. ʻO ka PBAT he copolymer o nā polyesters aliphatic a me nā aromatic, kahi e hui pū ai i nā waiwai degradation maikaʻi loa o nā polyesters aliphatic a me nā waiwai mechanical maikaʻi o nā polyesters aromatic. Ua like loa ka hana o ka PBAT me ka LDPE. Hiki ke hoʻohana ʻia nā lako hana LDPE no ka puhi kiʻiʻoniʻoni.
