Intuthuko yakamuva kubuchwepheshe be-polyurethane (PU) evimbela umlilo ishintsha amazinga okuphepha kwezinto kuzo zonke izimboni. Izinkampani zaseShayina zihola ngama-patents amasha: I-Jushi Group yathuthukisa i-nano-SiO₂-enhanced waterborne PU, yafinyelela inkomba ye-oxygen engu-29% (ukumelana nomlilo kweBanga A) ngokusebenzisana kwe-phosphorus-nitrogen, kuyilapho i-Guangdong Yurong idale i-ternary intumescent flame retardant ebopha ngamakhemikhali kuma-molecule e-PU, iqinisekisa ukuphepha okuhlala isikhathi eside ngaphandle kokukhipha amanzi. I-Kunming Zhezitao ihlanganise imicu ye-carbon eguquliwe yi-phosphate kuma-elastomers e-PU, ikhulisa ukuzinza kokushisa kanye nokwakheka kwe-char ngesikhathi sokushisa.
Ngesikhathi esifanayo, ucwaningo lomhlaba wonke luthuthukisa izixazululo ezinobungani nemvelo. Ucwaningo lwe-ACS Sustainable Chemistry lwango-2025 luqokomise izinhlelo ze-phosphorus/silicon ezingenayo i-halogen ezivumela ngasikhathi sinye ukumelana nomlilo kanye nokungaconsi ku-PU etholakala emanzini. I-nano-silica etholakala kuma-husk elayisi ehlanganiswe ne-non-halogen retardants ikhombisa ithemba lama-PU foam aqhubekayo, okuthuthukisa izithiyo zokushisa ngaphandle kwentuthu enobuthi.
Iqhutshwa yimithetho eqinile yokuphepha komlilo—njenge-EU REACH kanye ne-California TB 117—imakethe yepulasitiki evimbela umlilo kulindeleke ukuthi ikhuphuke isuka ku-$3.5 billion (2022) iye ku-$5.2 billion ngo-2030, kanti i-Asia-Pacific ibusa u-40% wesidingo somhlaba wonke. Izinto ezintsha zibeka phambili ukulinganisela ukuphepha, ukuqina, kanye nomthelela wemvelo, okubonisa ukukhula okuguqukayo kwemikhakha yokwakha, yezimoto, neye-elekthronikhi.
