ʻO ka PBSA (polybutylene succinate adipate) he ʻano plastic biodegradable, i hana maʻamau ʻia mai nā kumu waiwai mōʻalihaku, a hiki ke hoʻohaʻahaʻa ʻia e nā microorganisms i loko o ke kaiapuni kūlohelohe, me ka helu decomposition ʻoi aku ma mua o 90% i nā lā 180 ma lalo o ke ʻano o ka composting. ʻO PBSA kekahi o nā māhele hoihoi loa i ka noiʻi a me ka hoʻohana ʻana i nā plastic biodegradable i kēia manawa.
Aia i loko o nā ʻano plastik biodegradable nā ʻāpana ʻelua, ʻo ia hoʻi, nā plastic degradable bio-based a me nā plastic degradable based petroleum.Ma waena o nā plastics degradable e pili ana i ka petroleum, ʻo nā polyesters diol acid dibasic nā huahana nui, me ka PBS, PBAT, PBSA, a me nā mea ʻē aʻe, i hoʻomākaukau ʻia me ka hoʻohana ʻana i ka waikawa butanedioic a me ka butanediol e like me nā mea maka, i loaʻa nā pono o ka pale wela maikaʻi, maʻalahi. -e loaʻa nā mea maka, a me ka ʻenehana makua.Ke hoʻohālikelike ʻia me PBS a me PBAT, he haʻahaʻa haʻahaʻa ko PBSA, kahe wai kiʻekiʻe, crystallization wikiwiki, paʻakikī maikaʻi loa a me ka hoʻohaʻahaʻa wikiwiki ʻana i ke kaiapuni kūlohelohe.
Hiki ke hoʻohana ʻia ka PBSA i ka ʻeke, nā mea e pono ai i kēlā me kēia lā, nā kiʻiʻoniʻoni mahiʻai, nā mea lapaʻau, nā mea paʻi 3D a me nā māla ʻē aʻe.
