Polyurethane thovu ili ndi zabwino zambiri komanso zofunikira. Choyamba, mphamvu yake yowonjezera yowonjezera. Pambuyo popopera, chithovucho chimakula mofulumira mpaka 20-80 kuchulukitsa mphamvu yake yoyambirira, kapena kupitilira apo. Izi zimathandiza kuti azitha kudzaza mipata yosakhazikika ndi pores, kupewa zovuta zowonongeka ndi zosagwirizana zomwe zimagwirizanitsidwa ndi zodzaza miyambo.
Chachiwiri, chikuwonetsa kulimba mtima kwakukulu. Chithovu chochiritsidwa cha polyurethane chimapanga thovu lolimba lomwe limamatira molimba ku magawo osiyanasiyana monga nkhuni, zitsulo, ndi konkire. Mphamvu zake zometa ubweya zimafika pa 0.5-1.0 MPa, kuposa zomatira wamba. Izi zimapangitsa kuti zikhale zopambana pakuwonjezera structural.
Kutsekereza madzi ndi kusungunula kutentha ndi chinthu china chowunikira. Maselo otsekedwa-maselo a thovu nthawi zambiri amaposa 90%, zomwe zimalepheretsa chinyezi kulowa ndikupangitsa kukhala koyenera kumalo achinyezi. Panthawi imodzimodziyo, kutsika kwake kwa kutentha kwapakati (pafupifupi 0.02-0.03 W/m·K), kangapo kuposa kwa zipangizo zotchinjiriza zachikhalidwe, kumapangitsa kugwiritsidwa ntchito kwambiri pomanga chitetezo champhamvu.
Kuphatikiza apo, thovu la polyurethane limakhalanso ndi mphamvu zabwino zotchinjiriza mawu. Mapangidwe a thovu amayamwa mafunde amawu ndikuchepetsa kufalikira kwa phokoso, kuwapangitsa kuti azigwiritsidwa ntchito kwambiri kusindikiza zitseko ndi mazenera pazokongoletsa kunyumba kuti azikhala bwino. Amalimbana kwambiri ndi dzimbiri, kukana ma acid, alkalis, ndi zosungunulira za organic, zomwe zimawapangitsa kukhala oyenera kugwiritsidwa ntchito m'mafakitale.
Kuchokera pakuwona kwakuthupi, nkhaniyi ndi yopepuka, yokhala ndi kachulukidwe kochiritsidwa kokha 20-50 kg/m³, zomwe sizimawonjezera katundu wamapangidwe. Lilinso ndi kuchuluka kwa elasticity, yokhoza kupirira mapindikidwe omwe amadza chifukwa cha kufalikira kwa kutentha ndi kutsika, kuchepetsa chiopsezo cha kusweka.
Pankhani yoteteza chilengedwe, zomatira zamakono za polyurethane thovu nthawi zambiri zimagwiritsa ntchito zomata zotsika-zochepa kwambiri (VOC) zomwe zimachepetsa kuwononga mpweya. Malamulo oyenerera, monga GB 18583-2008 "Malire a Zinthu Zowopsa mu Zomatira Zokongoletsera Mkati ndi Zida Zokonzanso," amaika zofunikira pazidazi kuti zigwiritsidwe ntchito motetezeka.
Komabe, zoletsa ziyeneranso kuzindikirika, monga kukhudzidwira ndi kuwala kwa ultraviolet ndi ukalamba wokhala ndi mawonekedwe-kwanthawi yayitali, kuwapangitsa kukhala osayenerera malo osaphimbidwa. Zonsezi, komabe, izi zimapangitsa zomatira za thovu la polyurethane kukhala zinthu zomwe amakonda m'magawo ambiri.
