Mu PVC yofewa, popeza mapulasitiki amatha kuchepetsa kukhuthala kwa kusungunula, mafuta akunja a PVC okha omwe amafunikira.Mafuta odzola omwe amagwiritsidwa ntchito kwambiri mu PVC yofewa makamaka amaphatikiza mafuta acid, sopo wachitsulo, sera ya polyethylene, sera ya polyethylene oxidized, ester yautali wautali ndi amide.Muzojambula izi, Sainuowopanga seraadzakutengerani inu kumvetsa udindo waphula la polyethylenemu processing wa zofewa PVC.

1. Posakaniza mu chosakanizira, sera ya polyethylene imatha kusakaniza bwino zipangizo zomwe zili pamtunda wa chogudubuza ndikuletsa kutikitala kumamatira.
2. Mu kugubuduza processing, ntchito yapa waxndizofanana, koma zimakhalanso ndi ntchito zina zapadera, zomwe zimapindulitsa pakutengera zinthu ndikugudubuza pakati pa masikono, ndikuwonetsetsa kusalala kwa mafilimu opyapyala ndi mapepala.

3. Panthawi yopangira extrusion, sera ya polyethylene ingalepheretse kumamatira ndi kusungirako pakhoma la khoma la makina ndi wononga, zomwe zimapindulitsa pakugwetsa mankhwala ndikuonetsetsa kuti pamwamba pake pamakhala kusalala komanso kunyezimira.
4. Popanga jekeseni, sera ya polyethylene ingalepheretse zinthu kuti zisagwirizane ndi khoma la silinda la makina, zomwe zimakhala zopindulitsa pakupanga zinthu kuchokera ku nkhungu.Komabe, mu psinjika akamaumba processing, kokha ali ndi ntchito yomaliza.

Mu PVC yofewa, kuchuluka kwa sera ya polyethylene nthawi zambiri kumakhala magawo 0,25 mpaka 1.5.Mlingo weniweniwo umadalira mtundu ndi mlingo wa utomoni, plasticizer, ndi zigawo zina mu chilinganizo, monga zigawo zonsezi zingakhudze mphamvu ya mafuta.
