Lub ntsiab tivthaiv ntawm PU tawv npuag yog polyurethane (pU). Polyurethane yog cov kev sib txuas ua ke polymer tsim los ntawm pawg ntawm ownocyanate thiab cov pab pawg hydroxyl, uas muaj cov khoom siv hydroxyl, muaj zog ncab, thiab ua pa.
PU tawv yog dav siv nyob rau hauv kev kho kom zoo nkauj, khaub ncaws, khau, tsheb, tsheb thiab rooj tog zaum. Nws cov txiaj ntsig suav nrog cov mos muag muag zoo nkauj, muag muag tsis zoo, ua kom muaj zog, thiab nws kuj muaj, kev siv dej, yooj yim, thiab tus nqi qis.
Hauv cov txheej txheem ntau lawm, lub substrate ntawm PU tawv yog feem ntau tsis siv cov ntaub ntawv ua rau cov qauv hluavtaws zoo ib yam li ntawm cov tawv nqaij ntawm cov tawv nqaij Mesh. Cov qauv no ua rau cov tawv tawv zoo ib yam li cov tawv nqaij uas muaj qhov pom thiab lub cev, thiab muaj xim zoo nkauj dua.
