PBAT (polybutylene terephthalate) taƙaitaccen bayani ne na polybutylene terephthalate.Abubuwan da ake amfani da su don shirye-shiryen PBAT sune galibi adipic acid (AA), terephthalic acid (PTA), butylene glycol (BDO) azaman monomers, bisa ga wani kaso na esterification ko amsawar transesterification da amsawar polycondensation don haɗa polyadipic acid / butylene terephthalate. ester, sannan ta hanyar esterification, polycondensation da granulation matakai uku don shirya samfurin ƙarshe.PBAT yana ƙunshe da zoben benzene, don haka yana da babban kwanciyar hankali na kwayoyin halitta, amma ƙananan lalacewar kwayoyin halitta;kwayoyin halitta sun mamaye sararin samaniya kuma suna da amfani don haɗuwa da wasu kwayoyin;Yana da sarƙoƙi mai kitse, wanda ke ba da garantin sassauci mai kyau na sarƙoƙi na ƙwayoyin cuta kuma don haka kyakkyawan ductility.
PBAT polymer semi-crystalline, yawanci zafin jiki na crystallization yana kusa da 110 ° C, kuma wurin narkewa yana kusan 130 ° C, kuma yawancin yana tsakanin 1.18g/ml ~ 1.3g/ml.The crystallinity na PBAT ne game da 30%, da kuma Shore taurin ne sama da 85. PBAT ne a copolymer na aliphatic da aromatic kungiyoyin, wanda hadawa da kyau kwarai lalata Properties na aliphatic polyesters da kyau inji Properties na aromatic polyesters.Ayyukan aiki na PBAT yana kama da LDPE, kuma ana iya busa fim din tare da kayan aiki na LDPE.
PBAT yana da kyau biodegradability, kuma kayayyakin da aka yi tare da PBAT suna da sauƙi kuma gaba daya ƙasƙanci tare da taimakon kwayoyin halitta da kwayoyin cuta, ƙarshe sun canza zuwa carbon dioxide da ruwa.Saboda da kyau ductility, elongation a karya, zafi juriya da tasiri Properties, PBAT za a iya amfani da a cikin filastik marufi masana'antu, kamar shopping bags, datti jakunkuna, da dai sauransu, da kuma amfani da tableware, ciyawa fim da sauran filayen.
