Mu buryo bw'imitekerereze:
PC (Polycarbonate): Iyi ni pulasitiki idafite ibara, ibonerana kandi ishimishije mu buryo bwiza kandi yoroshye. Bitewe n'imiterere yayo idahumanya kandi idafite impumuro mbi, ndetse n'ubushobozi bwayo bwiza bwo gukumira imirasire y'izuba no kubika amazi mu kirere, PC ifite ubushyuhe bwinshi. Iguma idacika kuri -180°C kandi ishobora gukoreshwa igihe kirekire kuri 130°C, bigatuma iba igikoresho cyiza cyo gupakira ibiryo.
PET (Polyethylene Tereftalate) : Iki ni ikintu gikozwe mu buryo bwa kristu, kidafite ibara, kandi kibonerana, kandi gikomeye cyane. Gifite ishusho nk'iy'ikirahure, nta mpumuro, nta buryohe, kandi ntigihumanya. Gishobora gushya, gitanga urumuri rw'umuhondo rufite impande y'ubururu iyo gitwitswe, kandi gifite ubushobozi bwo kubuza gazi.
Ukurikije imiterere n'ikoreshwa:
PC: Ifite ubushobozi bwo guhangana n’ingaruka mbi kandi yoroshye kuyibumba, bigatuma ikorwamo amacupa, amacupa, n’ibindi bikoresho bitandukanye byo gupakiramo ibintu nk’ibinyobwa, inzoga n’amata. Ingorane nyamukuru ya PC ni uko ishobora kwangirika. Kugira ngo igabanye ibi mu gihe cyo kuyitunganya, hatoranywa ibikoresho fatizo bifite isuku nyinshi, kandi uburyo butandukanye bwo kuyitunganya bukagenzurwa cyane. Byongeye kandi, gukoresha resins zifite isuku nke imbere, nka polyolefins nke, nylon, cyangwa polyester mu kuvanga, bishobora kongera cyane ubushobozi bwayo bwo kwangirika no kwinjiza amazi.
PET: Ifite ubushobozi bwo kwaguka buciriritse kandi ifite igipimo gito cyo kugabanya ubushyuhe cya 0.2% gusa, ari kimwe cya cumi cy’ibumba rya polyolefini kandi iri hasi y’ibumba rya PVC na nylon, bigatuma ingano zayo zihoraho ku bicuruzwa. Ingufu zayo za mashini zifatwa nk'iza mbere, zifite ubushobozi bwo kwaguka busa n’ubwa aluminiyumu. Ingufu zo gukurura za filime zayo zikubye inshuro icyenda iy’ibumba rya polycarbonate na nylon zikubye gatatu, mu gihe imbaraga zayo zo gukurura zikubye inshuro eshatu kugeza kuri eshanu iy’ibumba risanzwe. Byongeye kandi, filime zayo zifite ubushobozi bwo kubuza ubushuhe no kubika impumuro nziza. Ariko, nubwo hari ibyo byiza, filime za polyester zirahenze, zigoye kuzifunga, kandi zikunze kwibasirwa n’amashanyarazi adahindagurika, niyo mpamvu zidakunze gukoreshwa zonyine; akenshi zihuzwa na resins zifite ubushobozi bwo kuziba ubushyuhe kugira ngo zikore filime zivanze.
Bityo rero, amacupa ya PET akorwa hakoreshejwe uburyo bwo gushushanya bwa biaxial stretching bushobora gukoresha neza imiterere ya PET, atanga urumuri rwiza, ubwiza bw'ubuso buri hejuru, kandi asa n'ikirahure, bigatuma aba amacupa ya pulasitiki akwiriye gusimbura amacupa y'ibirahure.
