I-PBAT yiplastiki ye-thermoplastic biodegradable. I-copolymer ye-butanediol adipate kunye ne-butanediol terephthalate. Ineempawu ze-PBA kunye ne-PBT. Ayinayo kuphela i-ductility efanelekileyo kunye nobude ngexesha lekhefu, kodwa kunye nokuchasana nobushushu obuhle kunye neempawu zempembelelo; Ukongeza, ikwane-biodegradability ebalaseleyo. Sesinye sezona zixhobo zisebenzayo ezinokubola kuphando lweeplastiki ezinokuguquguquka kwaye yenye yezona zinto zigqwesileyo zonakaliswe kwimarike.
I-PBAT yi-polymer eyi-crystalline eyi-semicrystalline. Ubushushu becrystallization buhlala bujikeleze i-110 ℃, indawo yokunyibilika imalunga ne-130 ℃, kwaye ukuxinana kuphakathi kwe-1.18g/ml kunye ne-1.3g/ml. I-crystallinity ye-PBAT imalunga ne-30%, kwaye ukuqina konxweme kungaphezulu kwe-85. I-PBAT yi-copolymer ye-aliphatic kunye ne-aromatics polyesters, edibanisa iipropati ezigqwesileyo zokuthotywa kwe-aliphatic polyesters kunye neempawu ezintle zomatshini ze-polyester ezivumba. Ukusebenza kwe-PBAT kufana kakhulu naleyo ye-LDPE. Izixhobo zokulungisa i-LDPE zingasetyenziselwa ukuvuthela ifilimu.
