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 burburka uu ka badan yahay 90% 180 maalmood gudahooda iyadoo la eegayo xaaladda bacriminta. PBSA waa mid ka mid ah qaybaha ugu xamaasadda badan ee cilmi-baarista iyo adeegsiga balaastikada nooledegradable hadda.
Bacaha noolaha ah waxaa ka mid ah laba qaybood, kuwaas oo kala ah, balaastikada wax-ka-qabashada bio-based iyo batroolka-ku-saleysan baatroolka. Baatroolka ku salaysan batroolka, polyester-ka dibasic acid diol polyesters ayaa ah 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.
