The polymer molecules are small and coil-shaped, or folded when cold. Oil viscosity is graded by measuring the time it takes for a standard amount of oil to flow. In general, silicone oil exhibit better resistance against temperature induced viscosity drop at atmospheric pressure, however, this resistance probably loosens up under pressure. The viscosity of a liquid as a function of temperature can be approximated with the Andrade correlation. In that state, they do not increase the oil’s viscosity, as there is rather low friction on the wetted surfaces in the engine and in the liquid itself. The use of any of the calculators' results is at the user's sole risk. This is typically designated in units of centipoise or poise but can be expressed in other acceptable measurements as well. Calculate the viscosity at a given temperature, when the viscosity is known at two temperatures. .

The viscosity of SIL 180 is about 10 times higher than water, which limits the convection. Methyl-silicone oil not only has density similar to that of the precursor, but also has high steam point, which determines its low viscosity and thermal stability in high polymerization temperature. It is therefore an excellent demonstration sample. Undersaturated oil viscosity is determined as a function of gas saturated oil viscosity and pressure above saturation pressure. 1-800-295-2392 or click below to call one of our regional representatives. *The marks followed by an asterisk (*) are trademarks of Momentive Performance Materials Inc.
