  • LUBRICANT COMPOSITION WITH AN IMPROVED VISCOSITY CHARACTERISTIC AT LOW OPERATING TEMPERATURE
    Publication number: 20190300808
    Abstract: A lubricant composition with a comb polymer and a synthetic base oil has improved viscosity characteristics at low operating temperatures. In addition, a comb polymer can be used for producing a lubricant having an R-factor of less than or equal to 8, wherein the R-factor is defined as the ratio of the kinematic viscosity at ?20° C. and the kinematic viscosity at +20° C.

  • HYDRAULIC FLUIDS IN PLASTIC INJECTION MOLDING PROCESSES
    Publication number: 20170218295
    Abstract: 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.

  • USE OF COMB COPOLYMERS FOR IMPROVING SCUFFING LOAD CAPACITY
    Publication number: 20120258899
    Abstract: The present invention relates to the use of comb polymers comprising, in the main chain, repeat units derived from polyolefin-based macromonomers with a molecular weight of at least 500 g/mol, and repeat units derived from low molecular weight monomers with a molecular weight less than 500 g/mol, for improving the load-bearing capacity of hydraulic fluids. Furthermore, the present invention describes new hydraulic fluids.
