Low-density polyethylene (LDPE) ndi utomoni wopangidwa pogwiritsa ntchito njira yoponderezedwa kwambiri kudzera mu polymerization yaulere ya ethylene ndipo imatchedwanso "high-pressure polyethylene".Popeza unyolo wake wa molekyulu uli ndi nthambi zambiri zazitali komanso zazifupi, LDPE imakhala yocheperako kuposa polyethylene yapamwamba kwambiri (HDPE) ndipo makulidwe ake ndi otsika.Imakhala ndi kuwala, kusinthasintha, kukana kwabwino kwa kuzizira komanso kukana mphamvu.LDPE ndi yokhazikika pamakina.Ili ndi kukana kwabwino kwa ma acid (kupatula ma oxidizing acids), alkali, mchere, zinthu zabwino kwambiri zamagetsi zamagetsi.Kulowa kwake kwa nthunzi ndikotsika.LDPE imakhala ndi madzi ambiri komanso kutheka bwino.Ndi oyenera kugwiritsidwa ntchito mitundu yonse ya njira thermoplastic processing, monga jekeseni akamaumba, extrusion akamaumba, kuwotcherera, rotomolding, ❖ kuyanika, thovu, thermoforming, otentha-ndege kuwotcherera ndi kuwotcherera matenthedwe.
