Our viscosity index improvers
CHEMPOL P20 & P30 by Chempol – Additives & Chemical Specialty
ESPRENE SPO by Sumitomo Chemical
Our viscosity index improvers help lubricants maintain their viscosity and film-forming ability in changing temperatures. Viscosity index improvers are polymeric and are added to reduce lubricant viscosity changes at high and low temperatures. Mineral oil lubricants become less effective at high temperatures because heat reduces their viscosity and film-forming ability.
Our viscosity index improvers are primarily used in multigrade engine oils, gear oils, automatic transmission fluids, power steering fluids, greases, and some hydraulic fluids.
