Impumelelo yakutsha nje kwitekhnoloji ye-polyurethane (PU) ebuyisela idangatye ilungisa ngokutsha imigangatho yokhuseleko lwemathiriyeli kuwo wonke amashishini. Iifemu zaseShayina zikhokela ngamalungelo awodwa omenzi wechiza: Iqela leJushi liphuhlise i-nano-SiO₂-ephuculweyo ye-PU yamanzi, ifumana isalathisi se-oksijini ye-29% (iBanga A ukumelana nomlilo) ngokusebenzisa i-phosphorus-nitrogen synergy, ngelixa i-Guangdong Yurong yenza i-ternary intumescent flame retardant ukuba iikhemikhali zibophelela kwii-molecule ze-PU ngaphandle kokuhlala ixesha elide, ukuqinisekisa ukhuseleko olude. I-Kunming Zhezitao edibeneyo i-phosphate-modified carbon fibers kwi-PU elastomers, ukunyusa ukuzinza kwe-thermal kunye nokwakhiwa kwe-char ngexesha lokutsha.
Ngaxeshanye, uphando lwehlabathi luqhubela phambili izisombululo ezilungele indalo. Uphononongo lwe-2025 ACS Sustainable Chemistry luqaqambise iinkqubo ze-halogen-free phosphorus/silicon ezenza kwangaxeshanye zikwazi ukuxhathisa amadangatye kunye nokuchasana nokuthontsiza kwi-PU yamanzi. I-Rice husk-derived nano-silica idityaniswe ne-non-halogen retardants ibonisa isithembiso sokugcinwa kwe-PU foams, ukunyusa imiqobo ye-thermal ngaphandle komsi onetyhefu.
Iqhutywe yimimiselo engqongqo yokhuseleko lomlilo-njenge-EU REACH kunye ne-California TB 117-imarike yeplastiki elawulwa ngumlilo iqikelelwa ukuba inyuke ukusuka kwi-3.5 yeebhiliyoni zeedola (2022) ukuya kwi-5.2 yezigidigidi ze-2030, kunye ne-Asia-Pacific ilawula i-40% yemfuno yehlabathi. Iinguqulelo ezintsha zibeka phambili ukulungelelaniswa kokhuseleko, ukuqina, kunye nefuthe lokusingqongileyo, umqondiso wokukhula kwenguqu kumacandelo okwakha, eemoto, kunye nele-elektroniki.
