PBAT ndi pulasitiki yowola yomwe imawola pogwiritsa ntchito thermoplastic. Ndi copolymer ya butanediol adipate ndi butanediol terephthalate. Ili ndi makhalidwe a PBA ndi PBT. Sikuti imangokhala ndi mphamvu yolimba komanso kutalika bwino ikagwa, komanso imakhala yolimba komanso yolimba chifukwa cha kutentha; Kuphatikiza apo, ilinso ndi mphamvu yabwino yowola. Ndi imodzi mwa zipangizo zomwe zimagwira ntchito kwambiri pofufuza za pulasitiki zomwe ziwola komanso imodzi mwa zipangizo zabwino kwambiri zomwe ziwola pamsika.
PBAT ndi polima wopangidwa ndi theka la kristalo. Kutentha kwa kristalo nthawi zambiri kumakhala pafupifupi 110 ℃, malo osungunuka amakhala pafupifupi 130 ℃, ndipo kuchuluka kwake kuli pakati pa 1.18g/ml ndi 1.3g/ml. Kuchuluka kwa kristalo kwa PBAT ndi pafupifupi 30%, ndipo kuuma kwa gombe kuli kopitilira 85. PBAT ndi copolymer ya polyester ya aliphatic ndi aromatic, yomwe imaphatikiza mphamvu zabwino kwambiri za polyester ya aliphatic ndi mphamvu zabwino zamakina za polyester ya aromatic. Kagwiridwe ka ntchito ka PBAT ndi kofanana kwambiri ndi ka LDPE. Zipangizo zopangira LDPE zitha kugwiritsidwa ntchito popopera filimu.
