Ko te PBSA (polybutylene succinate adipate) he momo kirihou pirau-koiora, he mea hanga i ngā rauemi tawhito, ā, ka taea te pirau e ngā moroiti i roto i te taiao tūturu, me te tere pirau neke atu i te 90% i roto i ngā rā 180 i raro i te tikanga whakawairakau. Ko te PBSA tētahi o ngā wāhanga tino hihiri i roto i te rangahau me te tono o ngā kirihou pirau-koiora i tēnei wā.
E rua ngā momo kirihou pirau-koiora, arā, ko ngā kirihou pirau-koiora me ngā kirihou pirau-hinu. I roto i ngā kirihou pirau-hinu, ko ngā polyester diol waikawa dibasic ngā hua matua, tae atu ki te PBS, PBAT, PBSA, me ētahi atu, e hangaia ana mā te whakamahi i te waikawa butanedioic me te butanediol hei rauemi mata, he pai te ātete ki te wera, he ngāwari ki te tiki rauemi mata, me te hangarau pakari. Ki te whakatauritea ki te PBS me te PBAT, he iti te ira rewa o te PBSA, he nui te rere, he tere te tioata, he tino pakari, ā, he tere ake te pirau i roto i te taiao.
Ka taea te whakamahi i te PBSA i roto i ngā takai, ngā mea e hiahiatia ana i ia rā, ngā kiriata ahuwhenua, ngā rauemi hauora, ngā rauemi tā 3D me ētahi atu mara.
