Viscosity Index Improvers

Viscosity Index Improvers

IPAC can supply you with a wide range of Viscosity Index Improvers (VIIs), whether you are interested in liquids or solids. Our carefully selected polymers, added to a lubricant to improve the range of effective viscosity, are designed specifically for the lubricants market, unlike many polymers sold as VIIs into the market today. They effectively thicken the oil as temperature increases. This means that the lubricating effect of mineral oils can be extended across a wider temperature range. A balance between thickening efficiency and shear stability is important when selecting a polymer for use as a viscosity improver. IPAC VIIs give you the highest possible degree of thermal and oxidative stability when added into your formulations and blends. These components are primarily used in multi-grade engine oils, gear oils, automatic transmission fluids, power steering fluids, greases, and some hydraulic fluids.
