Chisa cha uchi wa polima, chomwe chimadziwikanso kutiPP uchi pachimake zakuthupi, ndi zinthu zopepuka, zamitundumitundu zomwe zimatchuka m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera komanso magwiridwe antchito. Nkhaniyi ikufuna kufufuza kuti zisa za polima ndi chiyani, ntchito zake komanso ubwino wake.

Chisa cha uchi wa polima ndi chinthu chophatikizika chopangidwa ndi magulu angapo a hexagonal opangidwa ndi polypropylene (PP) kapena utomoni wina wa polima. Maselo amapangidwa mwadongosolo lachisa, zomwe zimapangitsa kuti zinthuzo zikhale zolimba kwambiri komanso zowuma. Maonekedwe opepuka a uchi wa polima amawapangitsa kukhala abwino kwa mapulogalamu omwe kuchepetsa kulemera ndikofunikira, monga mafakitale apamlengalenga, magalimoto, zam'madzi ndi zomangamanga.

Chimodzi mwazinthu zazikulu zauchi wa polimandi mphamvu zake zazikulu ndi kuuma kwake, zomwe zimalola kuti zithe kupirira katundu wolemetsa ndi zotsatira zake pamene zikusunga umphumphu wake. Izi zimapangitsa kukhala chisankho chabwino kwambiri chazinthu zapakati pa masangweji a masangweji, kupereka kulimbikitsa ndi kuthandizira khungu lakunja. Kuphatikiza apo, mapangidwe a zisa amapereka mphamvu zabwino kwambiri zoyamwa mphamvu komanso kukana mphamvu, zomwe zimawapangitsa kukhala oyenera kugwiritsidwa ntchito pomwe chitetezo ku mphamvu zosunthika ndi kugwedezeka kumafunikira.

Kusinthasintha kwa zisa za uchi wa polima kumafikira kuzinthu zake zotentha komanso zoyimbira. Maselo odzaza mpweya mkati mwachisa cha njuchi amapanga chotchinga chogwira ntchito motsutsana ndi kutentha kwa kutentha, zomwe zimapangitsa kuti zikhale bwino kusankha kusungunula m'nyumba, magalimoto osungiramo firiji ndi ntchito zina zowononga kutentha. Kuphatikiza apo, mawonekedwe a porous zisa za uchi wa polima zimathandiziranso kuti mayamwidwe ake azimveka, ndikupangitsa kuti ikhale chinthu choyenera kuwongolera phokoso komanso kutsekereza m'malo osiyanasiyana.

Kuphatikiza pa mawonekedwe awo amakina ndi insulating,zisa za polimazimadziwikanso chifukwa cha kukana dzimbiri komanso kulimba. Kusakhazikika kwa polypropylene ndi utomoni wina wa polima womwe umagwiritsidwa ntchito popanga zisa za uchi zimapangitsa kuti zikhale zolimba kwambiri ku chinyezi, mankhwala ndi zinthu zachilengedwe, kuonetsetsa kuti zikugwira ntchito kwa nthawi yayitali komanso kudalirika pazovuta. Izi zimapangitsa zisa za uchi wa polima kukhala njira yabwino yogwiritsira ntchito m'malo am'madzi, malo opangira mankhwala, ndi zida zakunja zomwe zimakhudzidwa ndi zinthu zowononga.

Ponseponse, zisa za uchi za polima zimapereka maubwino osiyanasiyana, kuphatikiza kupanga kopepuka, kulimba kwambiri, kutsekemera kwamafuta ndi ma acoustic, komanso kukana dzimbiri, kuwapanga kukhala zinthu zosunthika zoyenera kugwiritsa ntchito zosiyanasiyana. Pamene ukadaulo ndi njira zopangira zikupitilira patsogolo, kugwiritsa ntchito zisa za polima zikuyembekezeka kukulirakulira, kupereka mayankho aukadaulo ku mafakitale omwe akufuna zinthu zopepuka, zolimba komanso zogwira ntchito kwambiri. Kaya mugawo lazamlengalenga, magalimoto, apanyanja kapena zomangamanga,zisa za uchi za polima zikupitiriza kutsimikizira kufunika kwake monga zida zodalirika komanso zogwira mtima.
