Kev tawg tsis ntev los no hauv nplaim hluav taws kub-retardant polyurethane (PU) thev naus laus zis tau hloov kho cov qauv kev nyab xeeb ntawm cov khoom lag luam. Cov tuam txhab suav nrog cov ntawv pov thawj tshiab: Jushi Group tau tsim cov nano-SiO₂-txhim kho cov dej hauv PU, ua tiav cov pa ntsuas ntawm 29% (Qib A hluav taws kub) los ntawm phosphorus-nitrogen synergy, thaum Guangdong Yurong tsim ib qho ternary intumescent nplaim retardant uas muaj kev nyab xeeb rau PU-cov ntaub ntawv ntev ntev. tsis muaj leaching. Kunming Zhezitao integrated phosphate-hloov carbon fibers rau hauv PU elastomers, boosting thermal stability thiab char tsim thaum combustion.
Ib yam li ntawd, kev tshawb fawb thoob ntiaj teb nce qib kev daws teeb meem hauv eco. A 2025 ACS Sustainable Chemistry txoj kev tshawb fawb qhia txog halogen-dawb phosphorus / silicon systems uas ib txhij ua kom muaj nplaim taws thiab tiv thaiv dej hauv dej PU. Rice husk-derived nano-silica ua ke nrog cov uas tsis yog-halogen retardants qhia tau hais tias kev cog lus rau PU foams ruaj khov, txhim kho thermal thaiv tsis muaj pa luam yeeb.
Tsav los ntawm cov kev cai tiv thaiv hluav taws nruj heev-xws li EU REACH thiab California TB 117-kev lag luam nplaim hluav taws kub nyhiab tau kwv yees los ntawm $ 3.5 nphom (2022) mus txog $ 5.2 nphom los ntawm 2030, nrog Asia-Pacific dominating 40% ntawm kev thov thoob ntiaj teb. Kev tsim kho tshiab tseem ceeb tshaj qhov ntsuas kev nyab xeeb, kav ntev, thiab kev cuam tshuam ib puag ncig, qhia txog kev loj hlob ntawm kev tsim kho, tsheb, thiab khoom siv hluav taws xob.
