Cov khoom siv tshwj xeeb ntawm cov polyurethanes muaj txiaj ntsig zoo / siv hluav taws xob, cov khoom siv hluav taws xob tsawg, muaj kev tiv thaiv zoo heev, muaj kev tiv thaiv tsis tshua muaj cua sov, tsis tshua muaj cua sov kev ua haujlwm coefficientity dhau qhov kub ntau yam, tshwj xeeb kev nplij siab. Cov khoom zoo ntawm cov ntaub ntawv polyurethane ua rau lawv tseem ceeb hauv aviation thiab foob pob hluav taws engineering:
Rwb thaiv tsev ua los ntawm polyisocyanurate ua npuas ncauj, tsim los ua haujlwm hauv qhov kub thiab txias (xws li kev sib cais ntawm cov tso tsheb hlau luam nrog kua oxygen, thiab lwm yam).
Xim, adhesives, coatings, sealants, anti-corrosion sib tov.
Urethane bonding agents rau explosive propellants thiab composite cov ntaub ntawv.
Padding ntawm cov rooj zaum dav hlau thiab cov rooj zaum astronaut - ua los ntawm elastic thiab viscoelastic molded polyurethane ua npuas ncauj.
Fillers rau roj tso tsheb hlau luam ntawm tub rog aviation machinery - ua los ntawm reticulated block-structured saj zawg zog polyurethane ua npuas ncauj (tiv thaiv kev tawg ntawm roj vapors tau tov nrog huab cua thaum nkag mus rau submunition roj tso tsheb hlau luam).
Ntau qhov chaw ua los ntawm polyurethane elastomers, thermoplastic PU thiab nruj microcellular PU ua npuas ncauj.
