If you can provide viscosity information on your fluid at 2 set points (40 & 100✬ for example) and your operating temperature then we can extrapolate the operating viscosity from this information. If there are no accessible MSDS or COSHH Sheets available then you can also find in our Tech Zone some videos of various fluids at different viscosities to provide a rough comparison.įurthermore, we also have the ability to calculate operating viscosities based on actual operational temperatures. PROPERTIES: Clear, colorless, odorless fluids Extremely High Viscosities Non-Flammable High Damping. For example, imagine a substance so viscous, that it can retain its shape, say a cube, for several minutes almost without changing like a very viscous fruit jam. Super High Viscosity (300,000 Cst - 1,000,000 Cst). To be categorized at a certain ISO grade, the oil’s viscosity must fall within plus or minus 10 percent of the grade. The kinematic viscosity of a liquid can be looked upon as the liquid's resistance to flow under its own gravity head. The ISO VG refers to the oil’s kinematic viscosity at 40 degrees C. The centistoke (one hundredth of a stoke) is more generally used. Viscosity is a measure of internal resistance of fluid to the force causing the fluid to flow. For use with glass capillary viscometers, automatic viscometers and other viscosity measuring. Both units are large and, for practical purposes, it's more common to use the centipoise (cP) and centistoke (cSt), which are equal to one one-hundredth of the corresponding whole unit. In the metric system, the unit of kinematic viscosity is the square centimeter per second or the stoke. 5, General Purpose, Nominal 12.19 cSt 20C, Certified, 500 mL. If you have a fluid which isn’t contained within this list please send us your Material Safety Data Sheet or Chemical Safety Data Sheets with your enquiry so we can be sure to offer you a suitable pump for your requirements. Pure silicone oil in viscosity (cst) 50 Treated surfaces shine and get very good water-repellent properties Silicone oil lubricates metals, plastics and. Viscosity is often talked about in the context of shear stress, where shear stress is defined as stress that results from a force that acts parallel to the cross-section of the object. A corresponding unit for kinematic viscosity is the stoke (St), which is equivalent to 1 centimeter 2 per second. Viscosity is commonly understood to be a fluids thickness or resistance to flow. There are many units of measurement when referring to viscosity, below are some simple and useful conversions to understand the thickness of various fluids:ĬSt (Centistokes) or mm²/s x 4.62 = SSU (Seybolt Seconds Universal)ĬPs (Centipoise) or mPa = cSt / S.G (Density)īelow is a table of common fluid densities and viscosities across different temperature ranges based on reliable and trusted information collated from numerous sources within the industry and our own internal knowledge and experience.
