Publication number: 20170218295Abstract: The present invention relates to the use of hydraulic fluids in plastic injection molding processes. Thereby it was surprisingly found that the use of hydraulic fluids with the right combination of physical parameters like the viscosity grade, the viscosity index, the density and the dispersancy allows for significant energy savings in plastic injection molding processes (PIM). The PIM process is an industrial process to manufacture plastic parts at well controlled temperatures, pressures and cycle times. The energy consumption of the process became more important over the last years, however, other parameters like process stability and accuracy of plastic part parameters as well as machine protection and long oil drain intervals have to be satisfying.Type: ApplicationFiled: August 7, 2015Publication date: August 3, 2017Applicant: Evonik Oil Additives GmbHInventors: Frank Lauterwasser, Frank-Olaf Mähling, Robert Kolb, Thorsten Bartels, Thomas Schimmel, Stefan Maier, Michael Alibert

Patent number: 9677024Abstract: The present invention relates to an engine oil lubricant composition for use in internal combustion engines comprising one or more molybdenum containing compounds that deliver 1-1000 ppm molybdenum to the finished oil, one or more phosphorus containing compounds that deliver 25-650 ppm phosphorus to the finished oil, and one or more poly(meth)acrylate viscosity index improvers (VI improvers) that may or may not be functionalized, for improved fuel economy and turbocharger related deposits. In addition, the composition comprises an antioxidant system which is carefully balanced to provide improved fuel economy, comprising an aminic antioxidant, a phenolic antioxidant and an ashless dithiocarbamate. Additionally, the formulated oil may contain a dispersant poly(meth)acrylate, in addition to the PAMA VI improver, to reduce the amount of traditional succinimide dispersants.Type: GrantFiled: June 5, 2013Date of Patent: June 13, 2017Assignee: VANDERBILT CHEMICALS, LLCInventors: Carl K. Esche, Glenn A. Mazzamaro, Thorsten Bartels, David B. Gray
