Mafuta emukati anobatsira zvikuru pakugadzirisa PVC, sezvo achiita basa guru mukuderedza kukweshana pakati pemaketani emamorekuru ePVC, zvichikonzera kunyunguduka kwakaderera. Zvaari polar muchimiro, anoratidza kubatana kwakanyanya nePVC, zvichiita kuti zvinhu zvipararire zvakanaka.
Chimwe chezvakanakira zvikuru zvemafuta emukati memuviri kugona kwawo kuchengetedza kujeka kwakanaka kunyangwe paine mwero wakawanda. Kujeka uku kunodiwa zvikuru mukushandiswa uko kujeka kwekuona kwakakosha, senge muzvinhu zvinopenya zvekurongedza kana magirazi ekuona.
Chimwe chakanakira ndechekuti mafuta emukati haawanzo buritsa kana kutamisa pamusoro pechigadzirwa chePVC. Iyi nzira isingaburitse mvura inoita kuti chigadzirwa chekupedzisira chive nehunyanzvi hwekubatanidza, kunamira, uye kudhinda. Inodzivirira kutumbuka kwepamusoro uye inochengetedza kunaka kwechigadzirwa, ichivimbisa kushanda zvakanaka uye runako rwacho.

Mafuta ekunze anonyanya kukosha pakugadzirwa kwePVC, sezvo achiita basa guru mukuderedza kubatana pakati pePVC nenzvimbo dzesimbi. Mafuta aya anonyanya kushandiswa kwete nepasi pevhu, uye paraffin ne polyethylene waxes zviri mienzaniso inowanzoshandiswa. Kushanda kwemafuta ekunze kunoenderana nehurefu hwecheni yehydrocarbon, matavi ayo, uye kuvapo kwemapoka anoshanda.
Kunyange zvazvo mafuta ekunze achibatsira mukugadzirisa mamiriro ekushanda zvakanaka, chiyero chawo chinofanira kudzorwa nokungwarira. Paanoshandiswa zvakanyanya, anogona kukonzera migumisiro isina kunaka yakadai sekudonha kwemvura muchigadzirwa chekupedzisira uye kubuda kwemafuta pamusoro. Saka, kuwana chiyero chakakodzera mukushandiswa kwawo kwakakosha kuti uve nechokwadi chekuti kushandiswa kwacho kuri nani uye hunhu hwechigadzirwa chekupedzisira hunodiwa.
Nekuderedza kunamirana pakati pePVC nenzvimbo dzesimbi, mafuta ekunze anorerutsira kugadzirwa zvakanaka uye anodzivirira kuti zvinhu zvisabatire pamichina yekugadzirisa. Izvi zvinowedzera kushanda zvakanaka kwemaitiro ekugadzira uye zvinobatsira kuchengetedza kunaka kwechigadzirwa chekupedzisira.
