Polyethylene wax e sebelisoa haholo ka lipolasetiki e le dispersant bakeng sa li-pigments, e le setlolo bakeng sa metsoako ea PVC, e le mokhoa oa ho phalla le ho tsamaisana le PE le PP modifiers.
Lebitso le felletseng la PVC ke PVC.Mocheso oa eona oa ho phalla ha viscous o haufi haholo le mocheso oa ho senyeha, kahoo ho bonolo ho feta mefuta e sa tšoaneng ea ho senyeha nakong ea ts'ebetso, ho fella ka tahlehelo ea ts'ebeliso.
Ka hona, li-stabilizers tsa mocheso le lubricant li tlameha ho kenyelletsoa ha ho etsoa motsoako oa PVC, oa pele o ntlafatsa botsitso ba mocheso, oa morao o fokotsa likhohlano pakeng tsa liketane tsa limolek'hule tsa PVC, le matla a ho lokolla filimi pakeng tsa PVC e qhibilihisang le tšepe, ho ntlafatsa boiketlo ba ho sebetsana le PVC. lihlahisoa tse fapaneng.Wax ea polyethylene le boka ba polyethylene e nang le oxidized ke lisebelisoa tse tloaelehileng ho PVC.
