Polyurethane sandwich paneli ifata ibara ryiza cyane ryometseho urupapuro nkubuso.Kandi intangiriro ikozwe muri polyurethane, ifuro kandi igakira ku bushyuhe bwinshi, kandi ikorwa nuburyo bubiri bugenzurwa.Ifite imikorere myiza yubushyuhe hamwe no kunama neza, kubika amajwi no kurwanya umuriro.Ugereranije nizindi panne, ubunini buke burakenewe niba ushaka kugera kuntego imwe, kandi net net yinyubako iriyongera.
1.Imikorere idahwitse: Polyurethane ni B2 yo mu rwego rwa B2 itagira umuriro kandi ifite ogisijeni ≥28, ishobora kugabanya igihombo cy’umuriro.
2.Imikorere ya insulation: Ubushyuhe bwumuriro wa polyurethane ni 0.019-0.023w / mk, nikintu cyiza cyane cyo kubika ubushyuhe.
3.Ijwi ryiza ryamajwi: amajwi meza, kugabanya neza kwivanga kw urusaku rwo hanze.
4.Hidrophobicity ya polyurethane ni ≤ 0.5%, kandi ifite umwuka mwiza.
5.Ubucucike bwinshi ni hafi 42kg / m³, imbaraga nyinshi, ituze rirambye.
| Izina | Ubushyuhe bwumuriro （w / mk） | Umubyimba usabwa kugirango ugere ku ngaruka zimwe |
| PU | 0.019-0.023 | 40 |
| XPS | 0.027-0.031 | 60 |
| EPS | 0.037-0.041 | 80 |
| Ibice bya polystirene | ≤0.06 | 160 |
