Cov kev tshawb pom tshiab hauv cov thev naus laus zis polyurethane (PU) uas tiv taus hluav taws kub tau hloov kho cov qauv kev nyab xeeb ntawm cov khoom siv thoob plaws hauv kev lag luam. Cov tuam txhab Suav ua tus thawj coj nrog cov ntawv pov thawj tshiab: Jushi Group tau tsim cov nano-SiO₂-enhanced waterborne PU, ua tiav cov pa oxygen ntawm 29% (Qib A tiv taus hluav taws) los ntawm kev sib koom ua ke ntawm phosphorus-nitrogen, thaum Guangdong Yurong tsim cov ternary intumescent flame retardant uas sib txuas nrog PU molecules, ua kom muaj kev nyab xeeb ntev yam tsis muaj leaching. Kunming Zhezitao tau koom ua ke cov phosphate-modified carbon fibers rau hauv PU elastomers, txhawb kev ruaj khov thermal thiab char tsim thaum lub sijhawm combustion.
Tib lub sijhawm ntawd, kev tshawb fawb thoob ntiaj teb tau txhawb nqa cov kev daws teeb meem uas tsis ua rau ib puag ncig puas tsuaj. Ib txoj kev tshawb fawb ACS Sustainable Chemistry xyoo 2025 tau hais txog cov txheej txheem phosphorus/silicon uas tsis muaj halogen uas ua rau muaj kev tiv thaiv hluav taws thiab tiv thaiv kev ntws hauv PU dej. Cov nano-silica uas tau los ntawm cov husk nplej ua ke nrog cov tshuaj tiv thaiv uas tsis yog halogen qhia tau tias muaj kev cia siab rau cov ua npuas dej PU uas ruaj khov, txhim kho cov teeb meem thermal yam tsis muaj pa luam yeeb lom.
Vim muaj cov cai tswjfwm kev nyab xeeb hluav taws kub—xws li EU REACH thiab California TB 117—kev lag luam yas uas tiv taus hluav taws kub tau kwv yees tias yuav nce ntxiv ntawm $ 3.5 billion (2022) mus rau $ 5.2 billion los ntawm xyoo 2030, nrog rau Asia-Pacific tswj hwm 40% ntawm kev thov thoob ntiaj teb. Kev tsim kho tshiab muab qhov tseem ceeb rau kev sib npaug ntawm kev nyab xeeb, kev ruaj khov, thiab kev cuam tshuam rau ib puag ncig, qhia txog kev loj hlob hloov pauv rau kev tsim kho, tsheb, thiab khoom siv hluav taws xob.
