Mafuta a PVC (wax wa pe,op wax) akhoza kugawidwa mu mitundu iwiri.Ntchito yaikulu ya mafuta akunja ndi yakuti ali ndi kugwirizana kosauka ndi ma polima ndipo n'zosavuta kusuntha kuchokera kusungunuka kupita kunja, motero amapanga mafuta ochepa kwambiri pa mawonekedwe pakati pa pulasitiki kusungunuka ndi zitsulo.Mafuta amkati amagwirizana bwino ndi ma polima, chifukwa amachepetsa mgwirizano pakati pa mamolekyu a polima mkati mwa polima, potero kuwongolera m'badwo wamkangano wamkati kutentha ndi kusungunuka kwa pulasitiki.Zowona, mafuta ambiri amakhala ndi mphamvu ziwiri zamafuta amkati ndi akunja, m'malo mokhala ndi mphamvu imodzi, monga stearic acid.Kumayambiriro kwa kukonza, pamene kutentha kuli kochepa kapena mlingo uli wochuluka, makhalidwe odzola akunja amalamulira.Kutentha kukakwera, kuyanjana ndi PVC kumapangidwa bwino, ndipo mlingo ukakhala woyenerera, zokometsera zamkati zimakhala ndi gawo.

Mafuta a PVC amagawidwanso m'matenthedwe otsika kutentha, kuyatsa kutentha kwapakati, ndi kudzoza kutentha kwambiri.Kutentha kwamafuta otsika kumagwira nawo gawo loyambirira la kukonza, monga parafini, stearic acid, monoglyceride, butyl stearate, mowa wa stearic, etc;Sing'anga kutentha kondomu amagwira ntchito lubricating pakati siteji processing, mongapa wax, sera ya ope, lead stearate, cadmium stearate, ndi zina zotero;Kutentha kwapamwamba kumagwira ntchito yopangira mafuta pambuyo pake, monga calcium stearate, barium stearate, etc.

Kugwiritsa ntchito mafuta opangira mafuta pakupanga fomula ya PVC kuyenera kutsatira mfundo izi:
1. Kupaka kunja kumatsimikizira kuti mankhwalawo samamatira pamwamba pazitsulo ndipo samasokoneza zochitika za phala, ndipo zing'onozing'ono zimakhala bwino;
2. Kupaka mkati kuyenera kugwiritsidwa ntchito mosamala ndikuwonetsetsa kuti sikukhudza fluidity ndi plasticization;
3. Onsewa amathiridwa mafuta mkati, ndipo akulimbikitsidwa kugwiritsa ntchito mafuta odzola apamwamba, apakati, ndi otsika kutentha pamodzi momwe angathere.Amakhalanso oyenera mafuta akunja;
4. Zogulitsa zomwe zimafuna madzi abwino, monga mbiri, zokokera, ndi zina zotere, ziyenera kukhala ndi mafuta ochulukirapo kuposa mafuta akunja;Zogulitsa zomwe sizifuna pulasitiki wapamwamba, monga mapaipi, zimakhala ndi mafuta ambiri akunja;

5. Pamene kuchuluka kwa zodzaza kumawonjezeka, mafuta ayenera kuwonjezeredwa moyenerera.Mafuta opepuka a calcium amayamwa kwambiri, ndipo mayamwidwe olemera a calcium mafuta ndi otsika.Chidwi chiyenera kulipidwa mukachigwiritsa ntchito;
6. Zinthu zopangidwa ndi thovu ziyenera kuchepetsa kuchuluka ndi kugwiritsa ntchito mafuta monga parafini omwe amakhudza kuchita thovu, komanso kuonjezera mafuta otsekemera pamene amachepetsa kachulukidwe kapena kuonjezera calcium;
7. Kusalinganika kwamafuta kumafuna mfundo yosinthira mafuta amtundu wina kupita ku wina, kuti adziwe msanga chomwe chimayambitsa ndikuwonetsetsa kupanga bwino.
