Posankha zinthu zosungiramo zosungirako, PU (polyurethane) ndi mphira aliyense ali ndi ubwino ndi zovuta zake, zomwe ziyenera kutsimikiziridwa malinga ndi momwe amagwiritsira ntchito ndi zofunikira.
1. Makhalidwe a PU casters
1) Ubwino:
A. Kukana kwamphamvu kuvala: Zida za PU zimakhala ndi kuuma kwakukulu ndipo ndizoyenera kugwiritsidwa ntchito pafupipafupi kapena zochitika zolemetsa (monga nyumba zosungiramo katundu ndi malo ogwirira ntchito). Kutalika kwake nthawi zambiri kumakhala kotalika kuposa labala.
B. Mphamvu yabwino yonyamula katundu: yoyenera kunyamula zida zosungira katundu (monga mashelefu a mafakitale).
C. Kukaniza kwa Chemical/Mafuta: Osavunda mosavuta ndi mafuta kapena zosungunulira, zoyenera malo monga ma laboratories ndi mafakitale.
D. Mphamvu yabwino yochepetsera phokoso: Ngakhale kuti siikhala chete ngati mphira, ndiyopanda phokoso kuposa zida zolimba monga nayiloni.
2) Zoyipa:
A. Kusakhazikika bwino: Kumayamwa kwamphamvu kumatha kukhala kosakwanira pamalo olimba ngati pansi simenti.
B. Kutentha kwapang'onopang'ono: Kusinthasintha kungachepetse kumalo ozizira.
2. Makhalidwe a oponya mphira
1) Ubwino:
A. Mayamwidwe a Shock ndi anti slip: Rabara ndi yofewa komanso yoyenera pamalo osalala monga matailosi ndi pansi pamatabwa, imateteza bwino kugwedezeka ndikuteteza pansi.
B. Zothandiza kwambiri zochepetsera phokoso: zoyenera maofesi, nyumba, ndi malo ena omwe amafunikira bata.
C. Kusinthasintha kwa kutentha kwakukulu: kumasunga kusungunuka ngakhale kutentha kochepa.
2) Zoyipa:
A. Kusagwira bwino kwa mavalidwe: Kugwiritsa ntchito nthawi yayitali pamalo olimba kumatha kung'ambika.
B. Kukalamba kosavuta: Kutentha kwa nthawi yaitali ku mafuta ndi cheza cha ultraviolet kungayambitse ming'alu.
Kutengera zosowa zenizeni, PU nthawi zambiri imakhala yothandiza kwambiri m'mafakitale ndipo mphira ndi yoyenera kukhazikika kunyumba.
