  • Patent number: 10689593
    Abstract: This disclosure relates to a low viscosity lubricating turbine oil having a composition comprising a lubricating oil base stock, as a major component, and one or more lubricating oil additives, as minor components. The lubricating turbine oil has a kinematic viscosity of about 16 cSt to about 22 cSt at 40° C., a density of about 0.8 g/ml to about 0.9 g/ml, and an absolute evaporation loss at 150° C. of less than about 4%. This disclosure also relates to a method for improving energy efficiency in a turbomachine lubricated with the low viscosity lubricating turbine oil. This disclosure further relates to a method for improving energy efficiency while maintaining or improving deposit control and lubricating oil additive solvency in a turbomachine lubricated with the low viscosity lubricating turbine oil. This disclosure yet further relates to a method for improving solubility, compatibility and dispersancy of polar additives in the low viscosity lubricating turbine oil.

  • Publication number: 20200157328
    Abstract: A fiber or nonwoven and methods for making and using same are provided herein. The fiber or nonwoven can contain at least one primary polypropylene, at least one polyalphaolefin, and at least one propylene-based elastomer. The propylene-based elastomer can have a heat of fusion less than about 80 J/g. The propylene-based elastomer can also include greater than 50 wt % propylene and from about 3 to about 25 wt % units derived from one or more C2 or C4-C12 ?-olefins, based on a total weight of the propylene-based elastomer.
