Zvichangoburwa mutekinoroji-retardant polyurethane (PU) tekinoroji iri kugadziridza zviyero zvekuchengetedza zvinhu mumaindasitiri. Mafemu echiChinese anotungamira nemanovel patent: Jushi Boka rakagadzira nano-SiO₂-yakakwidziridzwa mumvura PU, inowana okisijeni index ye29% (Grade A fire resistance) kuburikidza nephosphorus-nitrogen synergy, uku Guangdong Yurong yakagadzira ternary intumescent flame retadant iyo kemikari zvisungo kune PU mamorekuru, zvichiita kuchengetedzwa kwenguva refu. Kunming Zhezitao yakasanganiswa phosphate-yakagadziridzwa kabhoni fibers muPU elastomers, inowedzera kugadzikana kwekupisa uye kuumbwa kwechar panguva yekupisa.
Saizvozvo, tsvagiridzo yepasirese inosimudzira eco-hushamwari mhinduro. A 2025 ACS Sustainable Chemistry chidzidzo chakaratidza halogen-isina phosphorus/silicon masisitimu ayo panguva imwe chete anogonesa murazvo kuramba uye anti-kudonha muPU mumvura. Rice husk-yakagadzirwa nano-silica yakasanganiswa neasiri-halogen retardants inoratidza chivimbiso chekusimudzira PU furo, inosimudzira zvipingamupinyi zvinopisa pasina utsi hune muchetura.
Inotungamirwa neyakaomesesa mitemo yekuchengetedza moto — seEU REACH neCalifornia TB 117 — musika wepurasitiki usingatsvage moto unofungidzirwa kuti uchakwira kubva pamadhora 3.5 bhiriyoni (2022) kuenda kumadhora 5.2 bhiriyoni panosvika 2030, neAsia-Pacific inotonga makumi mana muzana ekuda kwepasirese. Innovations inotungamira kuyera kuchengetedza, kusimba, uye kukanganisa kwezvakatipoteredza, zvichiratidza shanduko yekukura kwezvikamu zvekuvaka, zvemotokari, uye zvemagetsi.
