Chifukwa cha zovuta za mankhwala ophera tizilombo, pali mankhwala ophera tizilombo ndi mankhwala ophera tizilombo komanso mankhwala ophera mafuta, ndipo palinso zosiyana pakuwononga kwawo. M'mbuyomu, zomwe zimasungidwa kale, zidachitika kwambiri m'mabotolo kapena zitsulo. Poganizira zovuta zonyamula mathithi amathiramu komanso mfundo yoti zida zosinthika zomwe zimasinthika zimatha kusinthika, pogwiritsa ntchito matumba a pulasitiki ophera tizilombo toyambitsa matenda ndikuchitanso chitukuko.
Pakadali pano, palibe wowuma polyirethane zomatira zomwe zitha kukhala 100% zogwiritsidwa ntchito m'matumba ophera tizilombo ku China ngakhalenso padziko lapansi popanda kunenepa kapena zovuta. Titha kunenedwa kuti kuchuluka kwa tizilombo toyambitsa matenda kuli ndi zofunikira kwambiri kwa zomata, makamaka pokana kuchulukana, kukana mafuta, komanso kuthekera kopikisana ndi ma enters a xlene Mwa gawo lapansi, lili ndi zotchinga zabwino ndi kukana kuwonongeka. Kachiwiri, pamafunika kuti zomatira zimakhala ndi kukana kwakukulu. Kuyeserera kosintha kuyenera kuchitidwa panthawi yopanga, komwe kumaphatikizapo kuyika matumba opangidwa ndi madigiri ndi kuwaza kutentha kwa madigiri 50 kwapamwamba komanso osawonongeka. Ngati ali phee, zitha kutsimikizika kuti phukusi limatha kugwiritsa ntchito mankhwalawa. Ngati ndalama ndi kutaya zimachitika, zikuwonetsa kuti tizilombo toyambitsa matendawa sichingapangidwe.
