PBSA (polybutylene succinate adipate) waa nooc ka mid ah balaastikada noolaha, taas oo guud ahaan laga sameeyay kheyraadka fosilka, waxaana hoos u dhigi kara noolaha noolaha ee deegaanka dabiiciga ah, iyadoo heerka burburku uu ka badan yahay 90% 180 maalmood gudahooda iyadoo la eegayo xaaladda bacriminta. PBSA waa mid ka mid ah qaybaha xamaasadda leh ee cilmi-baarista iyo adeegsiga balaastikada noole-gaaban hadda.
Bacaha noolaha ah waxaa ka mid ah laba qaybood, kuwaas oo kala ah, balaastikada wax-ka-qabashada bio-based iyo batroolka-ku-saleysan balaastikada.Ka mid ah baatroolka batroolka ku salaysan, polyester-yada diol dibasic acid waa alaabta ugu muhiimsan, oo ay ku jiraan PBS, PBAT, PBSA, iwm. -si aad u hesho alaabta ceeriin, iyo tignoolajiyada qaan-gaadhka ah.Marka la barbar dhigo PBS iyo PBAT, PBSA waxay leedahay meel dhalaalaysa oo hooseeya, dareere sarreeya, crystallisation degdeg ah, adkeysi aad u wanaagsan iyo hoos u dhac degdeg ah oo deegaanka dabiiciga ah.
PBSA waxaa loo isticmaali karaa baakadaha, waxyaabaha maalinlaha ah loo baahan yahay, filimada beeraha, qalabka caafimaadka, qalabka daabacaadda 3D iyo meelo kale.
