Polyurethane yog ib qho laj thawj rau cov khoom siv zoo tshaj plaws rau kev tsim cov khau kev nyab xeeb. Cov pwm yuav tsum tau qis dua, thiab cov khoom tsim tau yooj yim rau kev nqis peev (lub siab ntawm pwm yog me me thaum foaming tsuas yog {{0}}.14 ~ 0.2Mpa).
Polyurethane yog cov khoom siv zoo tshaj plaws rau kev ua cov khau kev nyab xeeb. Txoj kev thib ob yog txoj kev molding yooj yim, uas tuaj yeem tsim cov khau khiab thiab khau. (PU puag thiab ntau yam ntaub ntawv muaj zog sib txuas). Ua nyob rau hauv niaj hnub kev lag luam.
Polyurethane yog cov khoom siv zoo tshaj plaws rau kev tsim cov khau kev nyab xeeb. Nws yog lub teeb heev, nrog lub ntiajteb txawj nqus ntawm tsuas yog {{0}}.3 ~ 0.8. Nws yog qhov sib zog ntau dua li cov khoom siv ib txwm siv. Nws yog qhov tsim nyog rau cov khau tuab-soled uas yuav tsum tau muaj kev cuam tshuam thiab perforation. Kev nyab xeeb khau thoob ntiaj teb (kev nyab xeeb) 15% ntawm cov khau) siv ib qho polyurethane (PU) ib leeg.
Polyurethane yog cov khoom siv zoo tshaj plaws rau kev tsim cov khau kev nyab xeeb. Qhov thib plaub yog vim li cas cov polyurethane ib leeg muaj cov yam ntxwv ntawm softness, warmth, roj kuj, flex kuj thiab hnav tsis kam. Nws yog ntau tshaj 6 npaug ntau hnav-resistant dua li roj hmab. Nws tuaj yeem hloov kho ntau yam raws li kev xav tau ntawm kev siv. Qhov ceev ceev thiab tawv ncauj, tuaj yeem ua rau ob-xim (ob chav ntom) ob tog ib leeg, thiab sab hauv ib leeg yog ib leeg xis yog ib tug xis elastic ua npuas ncauj.
