TOP POLYMERS FZC caters to the lubricant industry and has been a key supplier to the rubber industry for a variety of applications. For the lube oil industry we are distributors of various additives such as Viscosity Index Improvers, Detergents, Dispersants, Pour Point Depressants, Anti-Wear additives etc.
Silverson has developed the Disintegrator , a complete system for the solubilization of viscosity index improvers into luboils. The D consists of a custom built vessel fitted with a powerful high shear disintegrator workhead coupled to a Silverson In-Line mixer. A viscosity index improver comprising a polymer containing at least 70 wt.% of an alkyl (meth)acrylate monomer (the alkyl group bearing ten or less carbon atoms) as the constituent unit; and a lubricating oil prepared by adding the improver to a lube base oil selected from the group consisting of mineral oil, MLDW oil, high-viscosity-index mineral oil containing isomeric paraffin, hydrocarbon.
The viscosity index of oil is calculated from its viscosities at 40 and °C. The procedure for the calculation is given in ASTM Method D for Calculating Viscosity Index from Kine-matic Viscosity at 40 and °C .

Viscosity Index Improvers and Thickeners for Synthetic Lubricants, [Herbert Finger] on *FREE* shipping on qualifying offers. a specific viscosity range by adding polymer. The resulting oil can have a viscosity index in the range depending upon the polymer chosen.” Dr.
Stuart Briggs, chief scientist for InfineumUSALPinLinden,N.J.,says, “VI improvers (also called viscosity modifiers or VM) change the rheologi-cal behavior of a lubricant by reducing.
The viscosity of 10W/40 motor oils formulated with different viscosity index (VI) improvers has been measured at pressures up to MPa ( bar) over a wide temperature and shear rate range.
Impact of Viscosity Index Improvers (VII) on the formation of piston deposits in fuel economy engine oils In the recent years, the achievement of fuel economy through lower viscosity engine oil has been a topic of wide discussions among experts in the : Kien-Wee Tan, Boris Eisenberg, Philip A.
Hutchinson, Frank Lauterwasser. These provide a more stable viscosity and allow the formulation of oils with lower viscosity base oil (for easier cold starting) and yet which have adequate high temperature viscosity for engine protection.
VI improvers make up around 10% of the content of a typical multigrade luboil, and increase the raw material costs of the finished product. The viscosity index Viscosity index improvers book a measure of a fluid's change in viscosity relative to its change in temperature.
Viscosity index improvers resist the thinning that occurs in a lubricant as the temperature is increased. NEWS / January Innov Oil is proud to announce the markets first 1 SSI pellet-form viscosity index improver.
With treat-rates at less than half of conventional OCP polymers, the new X-Series range will improve the quality of your lubricants with significant cost-saving benefits. The viscosity index is a measure of a fluid's change in viscosity relative to its change in temperature.
Viscosity index improvers resist the thinning that occurs in a lubricant as the temperature is increased.
These additives are polymeric molecules that are sensitive to : Noria Corporation. Viscosity index improvers are available with permanent shear stability (Pssi) values between and Your TRiiSO Technical Sales Representative is available to assist you in the selection of the appropriate chemical that will provide the specific properties you are trying to obtain.
Afton Viscosity Index Improvers Viscosity control vs. temperature change is one of the most important aspects of an effective and long-lasting lubricant.
View the solutions from Afton Chemical and their HiTEC® Performance Additives. A fluid with a broad temperature operating window will boost productivity and reduce energy costs.
The all-season use of high-viscosity index fluids reduces fuel consumption, maintenance costs and waste oil disposal compared to monograde oils. Contact an Evonik. Viscosity Index (VI) is one approach used wid ely in the lubri- cating field to assess the variation of viscosity with temperature.
The VI of both mineral and sy n. To establish the ability of INFINEUM SV and KELTAN copolymers solutions in SAE W10 mineral oil as solvent to perform at low and high temperatures in a vehicle's engine, that is their capacity to improve the oil's viscosity index, the.
Viscosity Index (VI) improvers are long chain, high molecular weight polymers that function by causing the relative viscosity of an oil to increase more at high temperatures than at low temperatures. Generally this result is due to a change in the polymer’s physical configuration with increasing temperature of.

Or lower viscosity index mean better for cold starts. VI is nothing more than an "indicator" of an oil's ability to resist viscosity change with change in temperature.
In general, the wider the vis spread of a multi-vis oil, the higher the VI. Find sources: "Viscosity index" – news newspapers books scholar JSTOR (May ) (Learn how and when to remove this template message) The viscosity index (VI) is an arbitrary, unit-less measure of a fluids change in viscosity relative to temperature change.
It is mostly used to characterize the viscosity-temperature behavior of lubricating oils. To establish the ability of copolymer poly (alkyl methacrylate) solutions in rapeseed oil as solvent to perform at low and high temperatures in a vehicle's engine, that is their capacity to improve the oil's viscosity index, the.
The viscosity index of an oil or an oil formulation is an important physical parameter. Viscosity index improvers, VIIs, are comprised of five main classes of polymers: polymethylmethacrylates Cited by:. Innov is an innovative Singapore based company specializing in the development, production and marketing of high performance polymers for use in lubricant manufacturing.
