PBAT inonzi thermoplastic biodegradable plastics. Iyo copolymer yebutanediol adipate uye butanediol terephthalate. Iine maitiro ePBA nePBT. Iyo haina chete yakanaka ductility uye elongation panguva yekuzorora, asiwo yakanaka yekudzivirira kupisa uye kukanganisa zvivakwa; Uye zvakare, ine zvakare yakanakisa biodegradability. Ndicho chimwe chezvinhu zvinonyanya kushanda biodegradable zvinhu mukutsvagisa biodegradable mapurasitiki uye chimwe chezvakanakisa zvinoshatisa zvinhu pamusika.
PBAT inonzi semi crystalline polymer. Iyo tembiricha yecrystallization inowanzotenderedza 110 ℃, nzvimbo yekunyungudika inenge 130 ℃, uye density iri pakati pe1.18g/ml uye 1.3g/ml. Iyo crystallinity yePBAT inenge 30%, uye kuoma kwemahombekombe kunopfuura 85. PBAT inonzi copolymer yealiphatic uye inonhuhwirira polyesters, iyo inosanganisa yakanakisa degradation properties yealiphatic polyesters uye yakanaka mechanical properties yeanonhuwirira polyesters. Kugadziriswa kwePBAT kwakafanana neiyo yeLDPE. LDPE yekugadzirisa michina inogona kushandiswa kuridza firimu.
