Polyurethane nkhungu guluu
Kuchita bwino kwa njira, kumatha kuchiritsidwa kutentha kwa chipinda, nthawi yocheperako, ndipo mtundu ukhoza kuwonjezeredwa kuti musinthe mtundu.Rabara yomalizidwa imakhala ndi kukana kwabwino, kukana madzi, kuwonekera, kukhazikika bwino komanso kukula kokhazikika.
Itha kusintha nkhungu ya mphira wa silicon "mwala wachikhalidwe".Itha kugwiritsidwanso ntchito poyika zida zamagetsi, zodzigudubuza mphira, mbale ya rabala, gudumu la rabala ndi nkhungu ya nsapato ndi zinthu zina.
