Polyurethanes yog dav siv polymers uas yog tsim los ntawm reacting polyols nrog diisocyanates nyob rau hauv muaj cov tshuaj xws li catalysts thiab additives.Lawv yog siv los tsim ntau yam khoom lag luam hauv yuav luag txhua qhov kev lag luam, xws li hluav taws xob, tsheb, khau, kev tsim kho, ntim khoom, thiab lwm yam, los ua pwm rau hauv cov duab txawv txawv thiab txhim kho cov neeg siv khoom thiab cov khoom lag luam.

Polyurethane yog siv los ua npuas ncauj rau phab ntsa thiab lub ru tsev rwb thaiv tsev, ua npuas ncauj yooj yim hauv cov rooj tog zaum, thiab ua cov nplaum, coatings, thiab sealants rau automotive interiors.Tag nrho cov xwm txheej no yuav ua rau muaj txiaj ntsig121 PABmus rau polyurethane ua lag luam thaum lub sij hawm kwv yees xyoo 2022-2032.

Cov ntawv thov tseem ceeb ntawm polyurethane yog nyob rau hauv elastomers, foams, thiab coatings muab kev puas tsuaj zoo heev.Rigid polyurethane foams tau dav siv los ua cov ntaub ntawv rwb thaiv tsev vim yog kev sib xyaw ntawm cov nqi-zoo thiab cov khoom siv hluav taws xob tsawg.Kev muaj peev xwm kub tsis zoo, qhov dav ntawm cov qauv molecular hloov pauv, tus nqi qis, thiab kev puas tsuaj siab yog txhua yam txhawb kev lag luam kev loj hlob.

Txawm li cas los xij, kev muaj peev xwm huab cua tsis zoo, muaj peev xwm thermal tsawg dua, ua nplaim taws, thiab lwm yam, zoo li yuav cuam tshuam rau polyurethane xav tau kev loj hlob nyob rau xyoo tom ntej.
