PBAT ndi mapulasitiki a thermoplastic biodegradable.Ndi copolymer wa butanediol adipate ndi butanediol terephthalate.Ili ndi mawonekedwe a PBA ndi PBT.Zilibe ductility zabwino ndi elongation pa nthawi yopuma, komanso wabwino kukana kutentha ndi mphamvu katundu;Kuphatikiza apo, ilinso ndi biodegradability yabwino kwambiri.Ndi chimodzi mwazinthu zomwe zimatha kuwonongeka kwambiri pofufuza mapulasitiki osawonongeka komanso chimodzi mwazinthu zosawonongeka kwambiri pamsika.
PBAT ndi semi crystalline polima.Kutentha kwa crystallization kumakhala kozungulira 110 ℃, malo osungunuka ndi pafupifupi 130 ℃, ndipo kachulukidwe kali pakati pa 1.18g/ml ndi 1.3g/ml.The crystallinity wa PBAT ndi pafupifupi 30%, ndipo gombe kuuma ndi kuposa 85. PBAT ndi copolymer wa aliphatic ndi onunkhira polyesters, amene amaphatikiza kwambiri kuwonongeka katundu aliphatic polyesters ndi zabwino makina katundu wa polyesters onunkhira.Kukonzekera kwa PBAT ndikofanana kwambiri ndi kwa LDPE.Zida zopangira LDPE zitha kugwiritsidwa ntchito powombera filimu.
