29, 2014 /PRNewswire/ -- Lubricant additives can be categorized into ten major types based on their functions, which are dispersants, viscosity index improvers, detergents, antiwear, antioxidants, corrosion inhibitors, emulsifiers, friction modifiers, EP, PPDs, and others.
The viscosity index was calculated using the ISO 2909:2002 method.
High viscosity index to help ensure minimum viscosity change when variations in temperature occur.
The 400,000 metric tonnes per year plant will produce Group III very high viscosity index lubricant base oil - the raw material for high quality finished lubricants.
Although monogrades and multigrades have a close kinematic viscosity range, parameters like specific gravity, viscosity index and total base number gives a wide distinction between the two grades of oil .
This is due to its designed viscosity stability, as indicated by the lubricant's high viscosity index (VI).
Edward Kresge, a pioneer in EP viscosity index modifiers, polyolefin TPEs and tailored MWD EPDMs, was awarded the 2011 Charles Goodyear Medal from the Rubber Division, ACS, at its Spring Technical meeting.
Viscosity index (VI) is an important parameter that evaluates the dependence of lubricant viscosity on temperature.
