Ko ngā putanga hou o te hangarau polyurethane (PU) ārai-mumura kei te whakahou i ngā paerewa haumaru rauemi puta noa i ngā ahumahi. Ko ngā kamupene Haina kei te arahi me ngā mana pateni hou: I whakawhanakehia e Jushi Group he PU wai-whakarei ake nano-SiO₂, i tutuki ai he taupū hāora o te 29% (ātete ahi Tau A) mā te hononga phosphorus-hauota, i te mea i hangaia e Guangdong Yurong he ārai mura intumescent ternary e hono matū ana ki ngā ngota PU, e whakarite ana i te haumaru roa me te kore e mimiti. I whakauruhia e Kunming Zhezitao ngā muka waro kua whakarerekētia ki te phosphate ki roto i ngā elastomers PU, e whakanui ana i te pumau wera me te hanganga waro i te wā e tahuna ana.
I te wā kotahi, ka whakatairangahia e ngā rangahau o te ao ngā otinga hoa-taiao. I roto i tētahi rangahau ACS Sustainable Chemistry i te tau 2025, i whakaatuhia ngā pūnaha phosphorus/silicon kore-halogen e āhei ai te ātete mura me te ārai-maturuturu i roto i te PU wai. Ko te nano-silica i ahu mai i te kiri raihi me ngā aukati-kore-halogen e whakaatu ana i te tumanako mō ngā pahuka PU pumau, e whakarei ake ana i ngā ārai wera me te kore paowa paitini.
Nā ngā ture haumaru ahi pakari—pērā i te EU REACH me te California TB 117—e matapaetia ana ka piki ake te mākete kirihou ātete-ahi mai i te $3.5 piriona (2022) ki te $5.2 piriona i te tau 2030, ā, ko Āhia-Moana-nui-a-Kiwa te rangatira o te 40% o te tono o te ao. Ko ngā mahi auaha e whakatairanga ana i te whakataurite i te haumaru, te pakari, me te pānga ki te taiao, e tohu ana i te tipu whakarerekētanga mō ngā rāngai hanga, motuka, me te hikohiko.
