Abstract: Lubricant compositions comprising an oil of lubricating viscosity and a viscosity modifier that is a hydrocarbon polymer having a number average molecular weight (Mn) of less than 10,000 Daltons (Da). The viscosity modifier is present at greater than 2 wt %, based on a total weight of the lubricant composition. Exemplary hydrocarbon polymers include, but are not limited to, olefin polymers, such as polyisobutylene polybutene, ethylene ?-olefin copolymers, or combinations thereof.

Abstract: An aqueous fire sprinkler fluid containing a C4 or greater carboxylate salt for freezing point depression is described. The salts may be used in conjunction with glycols. The salts decrease the combustibility and give lower viscosity than higher glycol fluids, both benefitting fire sprinkler systems. These salt solutions are friendly to metal and CPVC pipes and are thus useful for fire sprinkler systems by not causing environmental stress cracking of the CPVC components and not being corrosive to the metal parts.

Abstract: The disclosed technology relates to a heat transfer system and heat transfer method employing a heat transfer fluid. In particular, the technology relates to an aqueous heat transfer fluid with low electrical conductivity, low flammability, and low freeze point that provides excellent peak temperature reduction in a heat transfer system, such as that for cooling battery modules in electric vehicles.

Abstract: Working fluids for a low global warming potential (GWP) refrigeration system comprising a compressor. The working fluid may comprise (a) a lubricating oil component comprising (i) at least one aromatic ester comprising the reaction product of an aromatic hydrocarbon having at least one carboxylic functional group and an (mono)alkylalcohol and/or glycol ether; and (b) a refrigerant.
