Polyisobutylene (PIB) feem ntau nthuav tawmib tug kuj tsawg flammability. Nws yog ib qho tsis muaj polar polymer, uas ua rau nws ruaj khov nyob rau hauv qhov kub thiab txias. Txawm li cas los xij, thaum PIB nws tus kheej tsis ignite yooj yim nyob rau hauv ib txwm tej yam kev mob, nws muaj peev xwm combust thaum raug tshav kub txaus los yog nplaim taws.
Hais txog kev siv, PIB feem ntau yog siv rau hauv cov khoom xws li lubricants, roj additives, thiab sealants qhov twg nws tiv taus cua sov yog qhov zoo. Nws thermal stability thiab tsis tshua muaj reactivity ua rau nws pab tau nyob rau hauv high-temperature ib puag ncig zoo li cav roj thiab raws li ib feem ntawm cov log tsheb. Txawm li cas los xij, nyob rau hauv rooj plaub uas PIB raug kub hnyiab los yog nplaim taws, nws yuav hlawv nrog cov pa luam yeeb tsawg, uas yog lwm qhov zoo dua hauv qee qhov chaw lag luam.
