Whakamahinga
He whakarewa mō ngā hinu, ngā ester cellulose, ngā mea pahū, me ētahi atu.
He tino pai ngā āhuatanga rere o te EGDA i roto i ngā paninga tunu me ngā enamel, me ngā wāhi e whakamahia ai ngā kapia kiriaku thermoplastic. He whakarewa pai hoki mō ngā paninga cellulosic, ā, ka taea te whakamahi i roto i ētahi pūnaha waituhi pēnei i ngā waituhi mata. Kua kitea te whakamahinga hei whakapiri kakara, ā, kua pūrongohia ngā whakamahinga i roto i ngā piripiri wai.
Ka taea te whakamahi i te ethylene glycol diacetate hei kaituku acyl mō te whakaputanga in situ o te waikawa peracetic, i te wā e hangaia ana te caprolactone e te chemoenzymatic. Ka taea hoki te whakamahi hei matū mua mō te hanga enzymatic o te poly (ethylene glutarate).

220KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
