Impumelelo yakutshanje kubuchwepheshe be-polyurethane egcina ilangabi (PU) itshintsha imigangatho yokhuseleko lwezinto kuzo zonke iifemu. Iinkampani zaseTshayina zikhokela ngeepatenti ezintsha: I-Jushi Group iphuhlise i-nano-SiO₂-enhanced waterborne PU, ifikelela kwi-oxygen index ye-29% (Grade A fire resistance) ngokusebenzisa i-phosphorus-nitrogen synergy, ngelixa i-Guangdong Yurong idale i-ternary intumescent flame retardant ebopha ngeekhemikhali kwiimolekyuli ze-PU, iqinisekisa ukhuseleko oluhlala ixesha elide ngaphandle kokukhupha amanzi. UKunming Zhezitao udibanise iifayibha zekhabhoni eziguqulwe yi-phosphate kwi-PU elastomers, ekhulisa uzinzo lobushushu kunye nokwakheka kwe-char ngexesha lokutsha.
Kwangaxeshanye, uphando lwehlabathi luqhubela phambili izisombululo ezinobuhlobo nokusingqongileyo. Uphononongo lwe-ACS Sustainable Chemistry luka-2025 lubonise iinkqubo ze-phosphorus/silicon ezingenayo i-halogen ezivumela ngaxeshanye ukumelana nomlilo kunye nokuchasana nokuvuza kwi-PU ephuma emanzini. I-nano-silica evela kwi-rice husk edityaniswe ne-non-halogen retardants ibonisa ithemba kwi-PU foams ezihlala zihleli, nto leyo ephucula imiqobo yobushushu ngaphandle komsi onobuthi.
Iqhutywa yimithetho engqongqo yokhuseleko lomlilo—njenge-EU REACH kunye neCalifornia TB 117—imarike yeplastiki ethintela umlilo kulindeleke ukuba inyuke ukusuka kwi-$3.5 yeebhiliyoni (2022) ukuya kwi-$5.2 yeebhiliyoni ngo-2030, apho i-Asia-Pacific ilawula i-40% yemfuno yehlabathi. Izinto ezintsha zibeka phambili ukulinganisela ukhuseleko, ukuqina, kunye nempembelelo yokusingqongileyo, nto leyo ebonisa ukukhula okuguquguqukayo kumacandelo okwakha, eemoto, kunye ne-elektroniki.
