Viscosity index improvers and pour point depressants
Viscosity index improvers based on polymethacrylates (PMA) or ethylene/propylene co-oligomers dissolved in mineral oil improve the viscosity/temperature behaviour. Their effect is to reduce the dependence of viscosity on temperature.
Pour point depressants are an effective solution for viscosimetric requirements at low temperatures. Their active ingredients help to retard crystallization of the molecules and thus improve the low-temperature behaviour of oil-containing systems.
