PBSA (polybutylene succinate adipate) yog ib hom biodegradable plastics, uas feem ntau yog tsim los ntawm cov khoom siv fossil, thiab tuaj yeem degraded los ntawm cov kab mob nyob rau hauv ib puag ncig ntuj, nrog rau tus nqi decomposition ntau dua 90% hauv 180 hnub nyob rau hauv cov xwm txheej ntawm composting.PBSA yog ib qho ntawm cov khoom siv biodegradable tam sim no.
Biodegradable plastics suav nrog ob pawg, uas yog, bio-based degradable plastics thiab roj av-raws li degradable plastics. Ntawm cov roj av-raws li cov yas degradable, dibasic acid diol polyesters yog cov khoom tseem ceeb, xws li PBS, PBAT, PBSA, thiab lwm yam, uas tau npaj los ntawm kev siv butanedioic acid thiab butanediol ua raw cov ntaub ntawv, uas muaj qhov zoo ntawm cov cua sov-tiv taus, yooj yim-rau-tau raw cov ntaub ntawv, thiab mature technology. Piv nrog PBS thiab PBAT, PBSA muaj cov ntsiab lus melting tsawg, siab fluidity, ceev crystallisation, zoo heev toughness thiab sai degradation nyob rau hauv ib puag ncig ntuj.
PBSA tuaj yeem siv rau hauv ntim, khoom siv txhua hnub, cov yeeb yaj kiab ua liaj ua teb, cov ntaub ntawv kho mob, 3D luam ntawv cov ntaub ntawv thiab lwm yam.
