Khoom hom xim ntawm cov xim tha xim
Ob tiam : PU khoom
Cov khoom siv tshuaj : Cov tshuaj Polyurethane (lub npe luv rau polyurethane) yog cov khoom siv polymer
Cov qauv ntawm cov qauv : Polyurethane yog cov khoom siv organic polymer tawm tshiab, lub npe hu ua "qhov loj tshaj plaws thib tsib"
Xwm hloov : Vim tias cov qauv ntawm polyurethane molecular structure, tib neeg hloov lawv cov elasticity, hardness thiab hydrophilicity los ntawm kev kho cov kev faib ua feem ntawm polyurethane thaiv cov khoom, ntawm cov uas polyurethane elastomers yog cov uas muaj feem xyuam tshaj plaws hauv cov ntaub ntawv siv rau polyurethane.
Polyurethanes tau siv rau hauv : tshuaj, hluav taws xob, textiles, kev kho mob, kev tsim kho thiab cov khoom siv hauv tsev, tsheb, hnab tawv, thiab lwm yam.
