Thumba la pulasitiki la PE ndi lalifupi la polyethylene. Ndi utomoni wa thermoplastic wopangidwa ndi polymer wochokera ku ethylene. Polyethylene ndi yopanda fungo ndipo imamveka ngati sera. Ili ndi kukana kutentha kochepa (kutentha kotsika komwe kumagwiritsidwa ntchito kumatha kufika -70~-100℃), kukhazikika kwa mankhwala, kukana ma acid ndi maziko ambiri (osagonjetsedwa ndi okosijeni), zosungunulira wamba kutentha kwa chipinda, kuyamwa madzi pang'ono, magwiridwe antchito abwino kwambiri amagetsi. Polyethylene yothamanga kwambiri ili ndi ubwino wa malo osungunuka kwambiri, kuuma kwambiri, mphamvu yayikulu, kuyamwa madzi pang'ono, ntchito yabwino yamagetsi, mphamvu yayikulu ya ma radiation, kukana mphamvu yayikulu, kutopa, kukana kuwonongeka, kukana mphamvu, kukana dzimbiri, kutalika kwakukulu, kukana mphamvu yayikulu, kukana kutayikira, kukana dzimbiri ndi zina zotero.
Makhalidwe ake ndi awa:
1. Chipangizo cha kristalo, kuyamwa pang'ono kwa chinyezi, kusinthasintha kwabwino, kusinthasintha kwa madzi komwe kumakhudzidwa ndi kupanikizika, kuumba kuyenera kugwiritsa ntchito jakisoni wopanikizika kwambiri, kutentha kofanana kwa zinthu, liwiro lodzaza mwachangu, kupanikizika kokwanira.
2. Kukana kuvala - kumapereka chitetezo cha nthawi yayitali kuti makina ambiri azioneka bwino kwambiri.
3. Kukana kukhudzidwa - Sungani mawonekedwe abwino nthawi zambiri pomwe kukhudzidwa sikuli kolimba.
4. Kukana kubowola - kumatha kupanga chotchinga cholimba ku madzi, kotero kuti sichingawononge chinthucho.
5. Kusinthasintha - kusintha malinga ndi mawonekedwe ambiri a pamwamba.
6. Yosavuta kugwiritsa ntchito - polyurethane imapereka yankho pa ntchito zambiri zovuta.
7. Zigawo za makina zosasinthasintha - Zigawo za makina zosasinthasintha sizimatulutsidwa zikagwiritsidwa ntchito.
Chikwama cha PE chili ndi mphamvu yabwino kwambiri yolimbana ndi dzimbiri, kutchinjiriza magetsi (makamaka kutchinjiriza pafupipafupi), kusintha mankhwala, kusintha kwa ma radiation, kumatha kuwonjezera ulusi wagalasi. Chili ndi malo otsika osungunuka, kuuma kwambiri, kuuma komanso mphamvu. Mphamvu yake yoyamwa madzi ndi yaying'ono. Polyethylene yotsika mphamvu ili ndi mphamvu zabwino zamagetsi komanso ma radiation, yofewa, yotalikirapo, mphamvu yokhudza kugwedezeka komanso kuthamanga kwambiri kwa kutuluka kwa madzi, komanso mphamvu yokhudza kugwedezeka kwambiri. Kutopa ndi kukana kuwonongeka. Polyethylene yotsika mphamvu ndi yoyenera kupanga zigawo zosagwirizana ndi dzimbiri ndi zigawo zoteteza kugwedezeka; Polyethylene yokwera mphamvu ndi yoyenera kupanga mafilimu opyapyala.
