| Internal lubricant TP-60 | |
| Density | 0.86-0.89 g/cm3 |
| Refractive index (80 ℃) | 1.453-1.463 |
| Viscosity (mPa.S, 80 ℃) | 10-16 |
| Asidhi Kukosha (mgkoh/g) | ＜10 |

Mafuta emukati akakosha ekuwedzera mukugadziriswa kwePVC, sezvo achiita basa rakakosha mukudzikisa kupesana pakati pePVC molecule cheni, zvichikonzera kuderera kunyunguduka viscosity. Kuve polar muzvisikwa, vanoratidza kuenderana kwakanyanya nePVC, kuve nechokwadi chekupararira kunoshanda mukati mechinhu chose.
Imwe yemabhenefiti akakosha emafuta emukati kugona kwavo kuchengetedza kujeka kwakanyanya kunyangwe pamadosi epamusoro. Kujeka uku kunodiwa zvakanyanya mumashandisirwo uko kujeka kwekuona kwakakosha, senge mupachena zvinhu zvekurongedza kana lenzi remaziso.
Imwe mukana ndeyekuti mafuta emukati haaite exudate kana kutamira pamusoro peiyo PVC chigadzirwa. Iyi isiri-exudation pfuma inovimbisa yakagadziridzwa welding, gluing, uye kudhinda zvimiro zvechigadzirwa chekupedzisira. Inodzivirira kubuda kwepamusoro uye inochengetedza kutendeseka kwezvinhu, kuve nechokwadi chekuita kunoenderana uye aesthetics.
| Mafuta ekunze TP-75 | |
| Density | 0.88-0.93 g/cm3 |
| Refractive index (80 ℃) | 1.42-1.47 |
| Viscosity (mPa.S, 80 ℃) | 40-80 |
| Asidhi Kukosha (mgkoh/g) | ＜12 |
| Kukosha kweIodine (gl2/100g) | ＜2 |
Mafuta ekunze akakosha ekuwedzera muPVC kugadzirisa, sezvo achiita basa rakakosha mukudzikisa kunamatira pakati pePVC nenzvimbo dzesimbi. Mafuta ekuzora aya haawanzo shandiswa polar, aine parafini uye polyethylene wax ari anowanzo shandiswa mienzaniso. Kubudirira kwekuzora kwekunze kunonyanya kuenderana nehurefu hweketani yehydrocarbon, branching yayo, uye kuvapo kwemapoka anoshanda.
Nepo mafuta ekunze achibatsira mukugadzirisa mamiriro ekugadzirisa, dosi yavo inoda kunyatsodzorwa. Pamadosi akakwira, anogona kutungamira kune zvisingadiwe mhedzisiro senge makore mune yekupedzisira chigadzirwa uye exudation ye lubricant pamusoro. Nekudaro, kuwana chiyero chakakodzera mukushandisa kwavo kwakakosha kuti ive nechokwadi chekuvandudza mashandiro uye inodiwa yekupedzisira-chigadzirwa zvivakwa.
Nekudzikisa kunamatira pakati pePVC nesimbi, mafuta ekunze anobatsira kugadzirisa uye kudzivirira zvinhu kubva pakunamatira kumichina yekugadzirisa. Izvi zvinowedzera kushanda kwemaitiro ekugadzira uye zvinobatsira kuchengetedza kuvimbika kwechigadzirwa chekupedzisira.
