Amapulasitiki avimbela amalangabi enzelwe ukumelana nokuvutha, ukubhebhetheka komlilo kancane, nokunciphisa ukukhishwa kwentuthu, okuwenza abaluleke kakhulu ezisetshenziswa lapho ukuphepha komlilo kubaluleke kakhulu. Lawa mapulasitiki ahlanganisa izithasiselo ezifana nenhlanganisela ye-halogenated (isb, i-bromine), ama-agent asekelwe ku-phosphorus, noma izigcwalisi ezingaphili njenge-aluminium hydroxide. Lapho zichayeka ekushiseni, lezi zithako zikhipha amagesi avimbela amalangabi, zakhe izendlalelo ze-char ezivikelayo, noma zimunce ukushisa ukuze kubambezeleke ukuvutha.
Esetshenziswa kakhulu ezimbonini zika-elekthronikhi, ezokwakha, nezimboni zezimoto, amapulasitiki avimba amalangabi ahlangabezana nezindinganiso eziqinile zokuphepha (isb., UL94). Isibonelo, zivikela izindawo ezivalekile zikagesi emililweni yesekethe emfishane futhi zithuthukise ukumelana nomlilo ezintweni zokwakha. Kodwa-ke, izithasiselo ze-halogenated zendabuko ziphakamisa ukukhathazeka kwemvelo ngenxa yokukhipha ubuthi, okushayela isidingo sezinye izindlela ezivumelana nemvelo njengezingxube ze-nitrogen-phosphorus noma izixazululo ezisekelwe kumaminerali.
Izinqubo ezintsha zakamuva zigxile ku-nanotechnology kanye nezithasiselo ezisekelwe ku-bio. Ama-Nanoclays noma ama-carbon nanotubes athuthukisa ukumelana nelangabi ngaphandle kokuyekethisa izakhiwo zemishini, kuyilapho amakhompiyutha asuselwa ku-lignin anikeza izinketho ezizinzile. Izinselele zisekhona ekulinganiseni ukuncipha komlilo nokuguquguquka kwezinto kanye nokusebenza kahle kwezindleko.
Njengoba imithetho iqinisa futhi izimboni zibeka phambili ukusimama, ikusasa lamapulastiki abamba ilangabi lilele ekwenziweni okungenabo ubuthi, ukusebenza okuphezulu okuhambisana nezimiso zomnotho eziyindilinga. Lokhu kuthuthukiswa kuqinisekisa izinto eziphephile, eziluhlaza ezisetshenziswa zesimanje.
