I te tau 2026, kua puta te dimethyl phthalate (DMP), he matū phthalate ester maha-whakamahinga, he iti hoki te utu, hei rauemi āwhina matua i roto i te umanga hanga paninga me te polymer cellulosic o te ao, e whai hua ana ki te akiaki i ngā whakapainga mahi pumau me te whakahoutanga hangarau i roto i ngā rāngai ahumahi maha o raro. Hei kaihanga kirihou tino whai hua me te whakarewa waro kohua nui me te whakauru pai, ka whakaatuhia e te DMP te hototahitanga pai ki te whānuitanga o ngā kapia cellulose, tae atu ki te nitrocellulose, te cellulose acetate me te ethyl cellulose. Nā tēnei hototahitanga ahurei ka waiho hei tāpiri mahi tino nui mō te hanga paninga ā-ahumahi kounga teitei, ngā peita whakaoti taonga me ngā hua kirihou cellulosic ngāwari, e noho ana i tētahi tūranga kore e taea te whakakapi i roto i ngā rauemi āwhina matū pai waenga me te iti.
Kua roa ngā paninga nitrocellulose parakore tuku iho e pāngia ana e ngā hapa o roto o ngā rauemi, tae atu ki te ngāwari o te kiriata, te ngawari o te pakaru i raro i ngā āhuatanga pāmahana iti, te koretake o te piri o te mata me te ngoikore o te ātete huarere i muri i te roa o te wā e pāngia ana e te taiao o waho. He maha ngā whakamātautau whakatairite ahumahi kua whakamanahia ko te tāpiri tika o te DMP parakore teitei ka taea te whakatika me te arotau i te hanganga hononga-ira o ngā kiriata paninga i te wā e whakamaroke ana. Ka whakanui ake i te ngāwari whānui, te kanapa o te mata maeneene, te ātete rakuraku me te ātete huarere roa o ngā paninga kua oti. I taua wā, ko te hanganga matū pumau me te matotoru ngawari o te DMP ka tino whakapakari i te kaha piri o ngā piripiri cellulose, ka whakaoti pai i ngā āhuatanga mamae ahumahi noa pēnei i te pakarukaru o te paparanga piripiri, te kiri me te ngoikore o te pakari e kitea whānuitia ana i roto i ngā whakapaipai hanga me ngā rauemi piri o roto o te motuka.
I roto i te mara ngaio o te tukatuka kirihou cellulosic, he mea tino pai te DMP hei whakangawari me te whakapūmau kirihou e pai ana ki te taiao mō ngā pepa kirihou cellulosic, ngā kiriata angiangi mārama me ngā hua whakapūmau werohanga. He rerekē i ngā whakapūmau kirihou iti-kounga noa e ngāwari ana te whakakorikori i ngā rauemi me te tino piki haere o te tere, ka taea e te DMP te whakataurite i te ngāwari me te pumau o te hanganga o ngā rauemi polymer, me te karo i ngā raruraru kounga noa pēnei i te tioata pāmahana iti, te piki haere o te tere pāmahana teitei me te pakarukaru o ngā hua. E matapaetia ana e ngā kaitātari mākete ngaio me te whakaoranga tonu me te whanaketanga tere o ngā ahumahi hangahanga o raro, te hiko hou o ngā motuka me te takai kai i te tau 2026, ka mau tonu te hiahia o te mākete o te ao mō te DMP kounga ahumahi parakore teitei i roto i ngā mara paninga ahumahi me ngā rauemi cellulosic i tētahi ia tipu pumau i ia tau, me te kaha whanaketanga mākete nui i te haurua tuarua o te tau.
