Ukuphumelela kwakamuva kubuchwepheshe be-polyurethane (PU) obubuyisela umlilo kubumba kabusha amazinga okuphepha okubalulekile kuzo zonke izimboni. Amafemu aseShayina ahola ngamagunya obunikazi anoveli: I-Jushi Group ithuthukise i-PU yamanzi ethuthukisiwe i-nano-SiO₂, yazuza inkomba ye-oksijini engu-29% (ukumelana nomlilo weBanga A) ngokusebenzisa i-phosphorus-nitrogen synergy, kuyilapho i-Guangdong Yurong idale i-ternary intumescent flame retadant ukuthi izibopho zamakhemikhali kuma-molecule e-PU, okuqinisekisa ukuphepha kokuhlala isikhathi eside. I-Kunming Zhezitao ihlanganise i-phosphate-modified carbon fibers ibe ama-PU elastomers, ithuthukisa ukuqina kokushisa kanye nokwakheka kwe-char ngesikhathi sokusha.
Ngasikhathi sinye, ucwaningo lomhlaba wonke luthuthukisa izixazululo ze-eco-friendly. Ucwaningo lwango-2025 lwe-ACS Sustainable Chemistry lwagqamisa amasistimu we-phosphorus/silicon angenayo i-halogen anika amandla kanyekanye ukumelana nelangabi kanye nokulwa nokuconsa ku-PU etholakala emanzini. I-nano-silica ethathwe ngamakhoba erayisi ehlanganiswe ne-non-halogen retardants ibonisa isithembiso samagwebu e-PU esimeme, okuthuthukisa imigoqo yokushisa ngaphandle kwentuthu enobuthi.
Iqhutshwa imithetho eqinile yokuphepha komlilo-njenge-EU REACH kanye ne-California TB 117-imakethe yepulasitiki engashiyi ilangabi kulindeleke ukuthi inyuke isuka ku-$3.5 billion (2022) iye ku-$5.2 billion ngo-2030, kanti i-Asia-Pacific ibusa i-40% yesidingo somhlaba wonke. Entsha ibeka phambili ukulinganisa ukuphepha, ukuqina, kanye nomthelela wemvelo, okubonisa ukukhula okuguquguqukayo kwemikhakha yezokwakha, yezimoto, neye-electronics.
