Ngokombono womqondo:
I-PC (i-Polycarbonate): Lena ipulasitiki engenambala, esobala ekhangayo futhi ebushelelezi. Ngenxa yokungabi nobuthi futhi engenaphunga, kanye nezakhiwo zayo ezinhle kakhulu zokuvimba i-UV kanye nokugcina umswakama, i-PC inezinga lokushisa elibanzi. Ayiphuki ku--180°C futhi ingasetshenziswa isikhathi eside ku-130°C, okwenza ibe yinto efanelekile yokupakisha ukudla.
I-PET (i-Polyethylene Terephthalate) : Lokhu kuyinto ecwebezelayo kakhulu, engenambala, futhi esobala futhi eqinile kakhulu. Inokubukeka okufana nengilazi, ayinaphunga, ayinambitheki, futhi ayinabo ubuthi. Iyavutha, ikhiqiza ilangabi eliphuzi elinomphetho oluhlaza okwesibhakabhaka uma ishiswa, futhi inezimpawu ezinhle zokuvimba igesi.
Ngokombono wezimpawu kanye nezinhlelo zokusebenza:
PC: Inokumelana okuhle kakhulu nokushayisana futhi kulula ukuyibumba, okuvumela ukuthi ikhiqizwe ibe amabhodlela, amabhodlela, kanye nezimo ezahlukahlukene zezitsha zokupakisha uketshezi olufana neziphuzo, utshwala, nobisi. Inkinga enkulu ye-PC ukuthi isengozini yokuqhekeka kokucindezeleka. Ukuze kuncishiswe lokhu ngesikhathi sokukhiqizwa, kukhethwa izinto zokusetshenziswa ezihlanzekile kakhulu, futhi izimo ezahlukene zokucubungula zilawulwa ngokuqinile. Ngaphezu kwalokho, ukusebenzisa ama-resin anokucindezeleka okuphansi kwangaphakathi, njengenani elincane lama-polyolefin, i-nylon, noma i-polyester yokuxuba okuncibilikisiwe, kungathuthukisa kakhulu ukumelana kwayo nokuqhekeka kokucindezeleka kanye nokumuncwa kwamanzi.
I-PET: Ine-coefficient ephansi yokwanda kanye nesilinganiso sokuncipha kokubumba esiphansi esingu-0.2% kuphela, okuyingxenye eyodwa kweziyishumi zama-polyolefin futhi ephansi kune-PVC ne-nylon, okuholela ekulinganisweni okuzinzile kwemikhiqizo. Amandla ayo okusebenza abhekwa njengangcono kakhulu, anezakhiwo zokwandisa ezifana ne-aluminium. Amandla okudonsa amafilimu ayo aphindwe kayisishiyagalolunye kunawe-polyethylene kanye ne-polycarbonate ne-nylon kathathu, kuyilapho amandla ayo okuthinta ephindwe kathathu kuya kahlanu kunamafilimu ajwayelekile. Ngaphezu kwalokho, amafilimu ayo anezivimbelo zomswakama kanye nezakhiwo zokugcina iphunga. Kodwa-ke, naphezu kwalezi zinzuzo, amafilimu e-polyester ayabiza kakhulu, kunzima ukuwavala ngokushisa, futhi athambekele kugesi ongashintshi, yingakho engavamile ukusetshenziswa wodwa; avame ukuhlanganiswa nama-resin anokuqina okungcono kokushisa ukudala amafilimu ahlanganisiwe.
Ngakho-ke, amabhodlela e-PET akhiqizwa kusetshenziswa inqubo yokubumba yokwelula i-biaxial angasebenzisa ngokugcwele izici ze-PET, enikeza ukucaca okuhle, ukukhanya okuphezulu kwendawo, kanye nokubukeka okufana nengilazi, okwenza abe amabhodlela epulasitiki afaneleka kakhulu ukufaka esikhundleni samabhodlela engilazi.
