PBSA (polybutylene succinate adipate) ndi mtundu wa pulasitiki wowola, womwe nthawi zambiri umapangidwa kuchokera ku zinthu zakale, ndipo ukhoza kuwonongeka ndi tizilombo toyambitsa matenda m'chilengedwe, ndi kuchuluka kwa kuwonongeka kwa zinthu zopitilira 90% m'masiku 180 pogwiritsa ntchito manyowa. PBSA ndi imodzi mwa magulu ofunikira kwambiri pakufufuza ndi kugwiritsa ntchito mapulasitiki owola pakadali pano.
Mapulasitiki osinthika amaphatikizapo magulu awiri, omwe ndi mapulasitiki osinthika omwe amapangidwa kuchokera ku bio-based ndi mapulasitiki osinthika omwe amapangidwa kuchokera ku petroleum. Pakati pa mapulasitiki osinthika omwe amapangidwa kuchokera ku petroleum, ma polyester a dibasic acid diol ndi omwe amapangidwa kwambiri, kuphatikizapo PBS, PBAT, PBSA, ndi zina zotero, zomwe zimapangidwa pogwiritsa ntchito butanedioic acid ndi butanediol ngati zopangira, zomwe zili ndi ubwino wokana kutentha bwino, zinthu zosavuta kupeza, komanso ukadaulo wokhwima.

PBSA ingagwiritsidwe ntchito popaka, zofunikira za tsiku ndi tsiku, mafilimu a zaulimi, zipangizo zachipatala, zipangizo zosindikizira za 3D ndi zina.
