LUBRICATING OIL COMPOSITION
A lubricating oil composition for automotive transmissions is disclosed. It offers an automotive transmission (especially a fuel-saving type) which satisfies all requirements as regards the properties of resistance to churning, maintenance of the oil film and low-temperature viscosity. It comprises a GTL low viscosity base oil and a Group 1 high viscosity base oil.
System, composition and method of application of same for reducing the coefficient of friction and required pulling force during installation of wire or cable
A composition and method for reducing the coefficient of friction and required pulling force of a wire or cable are provided. A composition of aqueous emulsion is provided that is environmentally friendly, halogen free and solvent free. The composition is compatible with various types of insulating materials and may be applied after the wire or cable is cooled and also by spraying or submerging the wire or cable in a bath. The composition contains lubricating agents that provide lower coefficient of friction for wire or cable installation and continuous wire or cable surface lubrication thereafter.
HYDRAULIC FLUIDS IN PLASTIC INJECTION MOLDING PROCESSES
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.
