摘要： A bio-lubricant composition includes a first component that includes a first triglyceride, which is part of a cooking oil; a second component that includes a first epoxidized triglyceride; a third component that includes a hydroxylated triglyceride; a fourth component that includes a first fatty acid ester moiety; a fifth component that includes a first epoxidized fatty acid ester; and a sixth component that includes a hydroxylated fatty acid ester. A mixture of the first to sixth components at room temperature have a viscosity between 40 and 200 centipoise, and the composition is substantially free of free fatty acids.

摘要： A fluid includes a base stock and one or more additives. The base stock has a viscosity index of at least 80, and either a kinematic viscosity at 40° C. of at least 320 cSt or a kinematic viscosity at 100° C. of at least 14 cSt. The base stock includes greater than or equal to about 90 wt % saturates, less than or equal to about 10 wt % aromatics, and a sum of terminal/pendant propyl groups and terminal/pendant ethyl groups of at least 1.7 per 100 carbon atoms. The fluid has a thermal conductivity measured according to ASTM D7896 at 140° C. of 0.12 W/m·K or greater.

摘要： An object of the present invention is to provide a grease composition which has little influence on the environment and has good rust prevention and water resistance against salt water such as sea water. The grease composition comprises a biodegradable base oil and a rust-preventive agent comprising a calcium sulfonate complex and a sorbitan fatty acid ester, wherein a total content of biodegradable organic substances in the grease composition is 75% by mass or more, and wherein a content of the rust-preventive agent is 2.5 to 30% by mass.
