Isikhwama sepulasitiki se-PE sifushane ngokuthi i-polyethylene. Siyi-thermoplastic resin eyenziwe nge-polymer evela ku-ethylene. I-Polyethylene ayinaphunga futhi izwakala njenge-wax. Inokumelana okuhle kakhulu nokushisa okuphansi (izinga lokushisa eliphansi lokusetshenziswa lingafinyelela ku--70~-100℃), ukuzinza okuhle kwamakhemikhali, ukumelana nama-acid amaningi kanye nezisekelo (akumelani ne-oxidation acid), i-solvent evamile ekamelweni lokushisa, ukumuncwa kwamanzi amancane, ukusebenza kahle kakhulu kokushisa kukagesi. I-polyethylene enomfutho ophezulu inezinzuzo zephuzu lokuncibilika eliphezulu, ubulukhuni obuphezulu, amandla aphezulu, ukumuncwa kwamanzi aphansi, umsebenzi omuhle kagesi, amandla aphezulu emisebe, ukumelana nomthelela ophezulu, ukukhathala, ukumelana nokuguguleka, ukumelana nomthelela, ukumelana nokugqwala, ukunwebeka okuphezulu, ukumelana nomthelela ophezulu, ukumelana nokuvuza, ukumelana nokugqwala njalo njalo.
Izici zayo zimi kanje:
1. Izinto ezicwebezelayo, ukumuncwa okuncane komswakama, ukugeleza okuhle, ukugeleza okuzwela ingcindezi, ukubumba kufanele kusebenzise umjovo wokucindezela okuphezulu, izinga lokushisa elifanayo lezinto, isivinini sokugcwalisa okusheshayo, ingcindezi eyanele.
2. Ukumelana nokugqokwa - kunikeza isivikelo sesikhathi eside sokubonakala kwemishini eminingi enembile kakhulu.
3. Ukumelana nomthelela - Gcina ubuqotho bokubonakala kwezicelo eziningi lapho umthelela ungenamandla khona.
4. Ukumelana nokubhoboza - kungakha isithiyo esiqinile oketshezini, ukuze lungagugi umkhiqizo.
5. Ukuzivumelanisa nezimo - ukuzivumelanisa nezimo eziningi zobuso.
6. Kulula ukuyisebenzisa - i-polyurethane inikeza ikhambi lokusetshenziswa okuningi okunzima.
7. Izingxenye zomshini ezingaguquki - Izingxenye zomshini ezingaguquki azikhululwa uma zisetshenziswa.
Isikhwama se-PE sinokumelana okuhle kakhulu nokugqwala, ukufakelwa kukagesi (ikakhulukazi ukufakelwa kwemvamisa ephezulu), ukuguqulwa kwamakhemikhali, ukuguqulwa kwemisebe, kungathuthukisa ifayibha yengilazi. Sinezinga lokuncibilika eliphansi, ukuqina okuphezulu, ubulukhuni namandla. Amandla aso okumunca amanzi mancane. I-polyethylene ephansi inezakhiwo ezinhle zikagesi nezemisebe, ngobumnene, ubude, amandla okushaya kanye nezinga lokuvuza eliphezulu, ngamandla okushaya aphezulu. Ukukhathala nokumelana nokuguguleka. I-polyethylene ephansi ifanelekela ukwenziwa kwezingxenye ezingamelani nokugqwala nezingxenye zokufaka; i-polyethylene ephansi ifanelekela ukwenza amafilimu amancane.
