Ngokwembono yengqiqo:
I-PC (iPolycarbonate): Le yiplastiki engenambala, ecacileyo nebukekayo kwaye ithambile. Ngenxa yokuba ayinatyhefu kwaye ayinavumba, kunye neempawu zayo ezibalaseleyo zokuthintela i-UV kunye nokugcina umswakama, i-PC inomlinganiselo omkhulu wobushushu. Ayinakwaphuka kwi -180°C kwaye ingasetyenziswa ixesha elide kwi-130°C, nto leyo eyenza ukuba ibe yinto efanelekileyo yokupakisha ukutya.
I-PET (iPolyethylene Terephthalate) : Le yinto ecwebezelayo kakhulu, engenambala, kwaye ecacileyo, eqinileyo kakhulu. Inembonakalo efana neglasi, ayinavumba, ayinancasa, kwaye ayinatyhefu. Iyatsha, ivelisa ilangatye elityheli elinomphetho oluhlaza okwesibhakabhaka xa itshisiwe, kwaye ineempawu ezintle zokuthintela igesi.
Ngokwembono yeempawu kunye nokusetyenziswa:
PC: Inokumelana okuhle kakhulu nempembelelo kwaye kulula ukuyibumba, nto leyo evumela ukuba yenziwe kwiibhotile, iijagi, kunye neendidi ezahlukeneyo zeekhonteyina zokupakisha ulwelo olufana neziselo, utywala, kunye nobisi. Eyona ngxaki iphambili yePC kukuba iyakwazi ukuqhekeka ngenxa yoxinzelelo. Ukunciphisa oku ngexesha lokuveliswa, kukhethwa izinto eziluhlaza ezicocekileyo kakhulu, kwaye iimeko ezahlukeneyo zokucubungula zilawulwa ngokungqongqo. Ukongeza, ukusebenzisa iiresini ezinoxinzelelo oluphantsi lwangaphakathi, njengee-polyolefins ezincinci, i-nylon, okanye i-polyester yokuxuba i-melt, kunokuphucula kakhulu ukumelana kwayo noxinzelelo kunye nokufunxwa kwamanzi.
I-PET: Inomlinganiselo ophantsi wokwandiswa kunye nezinga eliphantsi lokuncipha kokubumba eliyi-0.2% kuphela, eliyi-1/10 ye-polyolefins kwaye lingaphantsi kune-PVC kunye ne-nylon, nto leyo ebangela ubungakanani obuzinzileyo beemveliso. Amandla ayo oomatshini athathwa njengeyona ilungileyo, eneempawu zokwandiswa ezifana ne-aluminium. Amandla okutsalwa kweefilimu zayo aphindwe kasithoba kune-polyethylene kwaye aphindwe kathathu kune-polycarbonate kunye ne-nylon, ngelixa amandla ayo okuchaphazela ephindwe kathathu ukuya kahlanu kuneefilimu ezisemgangathweni. Ukongeza, iifilimu zayo zinomqobo womswakama kunye neempawu zokugcina ivumba. Nangona kunjalo, nangona ezi zibonelelo, iifilimu ze-polyester zibiza kakhulu, kunzima ukuzivala ngobushushu, kwaye zixhomekeke kumbane ongashukumiyo, yiyo loo nto zingafane zisetyenziswe zodwa; zihlala zidityaniswe neeresini ezinokuvaleka ngcono kobushushu ukwenza iifilimu ezidityanisiweyo.
Ke ngoko, iibhotile ze-PET ezenziwe ngenkqubo yokubumba i-biaxial stretching blow molding zinokusebenzisa ngokupheleleyo iimpawu ze-PET, zibonelela ngokubonakala kakuhle, ukukhanya okuphezulu, kunye nokubonakala okufana neglasi, nto leyo ezenza zibe ziibhotile zeplastiki ezifanelekileyo zokutshintsha iibhotile zeglasi.
