Insoluble m'madzi, sungunuka pang'ono mu ma hydrocarbons, etc. Imatha kukana kukokoloka kwa ma acid ambiri ndi ma alkalis, imakhala ndi mayamwidwe otsika amadzi, imasunga kusinthasintha kwa kutentha, ndipo imakhala ndi kutchinjiriza kwamagetsi.
Njira yopanga: Pali njira ziwiri zopangira: njira yothamanga kwambiri ya tubular ndi ketulo. Pofuna kuchepetsa anachita kutentha ndi kuthamanga, tubular ndondomeko jinirally amagwiritsa ntchito oyambitsa otsika komanso oyambitsa ntchito zambiri kuti ayambitse dongosolo la polymerization. High-purity ethylene ndiye zopangira zazikulu, ndipo propylene, propane, ndi zina zambiri zimagwiritsidwa ntchito ngati zosinthira kachulukidwe. The polymerization reaction ikuchitika pansi pa mikhalidwe ya 200 ℃ mpaka 330 ℃ ndi 150 mpaka 300 MPa pogwiritsa ntchito oyambitsa ntchito zapamwamba. Polima wosungunula anayambitsa polymerization mu riyakitala ayenera utakhazikika ndi kupatukana pansi pa kuthamanga, sing'anga kuthamanga, ndi otsika kuthamanga. Mpweya wozungulira wothamanga kwambiri umakhazikika ndikulekanitsidwa kenako ndikutumizidwa kulowera kwa ultra-high-pressure (300 MPa) kompresa. Mpweya wozungulira wapakatikati umakhazikika ndikulekanitsidwa kenako ndikutumizidwa kulowera kwa kompresa yothamanga kwambiri (30 MPa). Mpweya wozungulira wocheperako umazirala ndikulekanitsidwa kenako ndikusinthidwanso ndi kompresa yotsika (0.5 MPa). Polyethylene yosungunuka imasiyanitsidwa ndi kuthamanga kwambiri komanso kutsika kochepa, kenako imatumizidwa ku granulator kwa kudula madzi. Pa granulation, zowonjezera zowonjezera zitha kuwonjezeredwa molingana ndi magawo osiyanasiyana ogwiritsira ntchito, ndipo tinthu tating'onoting'ono timapakidwa ndikutumizidwa.
