Abstract:
A solid lubricant formulation useful for lubricating the flanges of locomotive wheels, railcar wheels, rail tracks and in applications where it is desirable to reduce friction when metal contacts metal. The solid lubricant formulation including at least one non-polylactic acid-based polymeric carrier, at least one polylactic acid-based polymer, and at least one lubricant powder.
Abstract:
This invention is a composition that includes a transesterified fatty acid ester resulting from the reaction of a fatty acid ester, in the presence of an acid, with a hydroxyl-containing compound. The fatty acid esters of the invention are selected from those with a carbon number of eight to twenty. The hydroxyl-containing compound is an alcohol having a carbon number between one and eighteen. The resulting composition is useful as a lubricant, as a heat transfer agent, as a rheological modifier and as a corrosion/moisture inhibitor, among other uses.
Abstract:
The present invention provides a beverage surfactant composition that includes a surfactant, a phosphonium compound, and a carrier; wherein the beverage surfactant composition exhibits stability as a solution or as a dispersion at a temperature of about 0° C. to about 8° C. The present invention also provides a container or a conveyor for a container having a surface that is at least partially coated with the composition. The present invention also provides a process for lubricating a container that includes contacting at least a portion of a surface of the container and the composition together. The present invention also provides a process for lubricating a conveyor that includes contacting at least a portion of a surface of the conveyor and the composition together.
Abstract:
Thermally formed thermoplastic articles can be protected from stress cracking in the presence of stress cracking promoting compounds by forming a shaped article comprising a thermoplastic and a liquid hydrocarbon oil composition. We have found that the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymeric structure of the stressed container to prevent or inhibit stress cracking in such materials. The methods and compositions of the invention are particularly useful in preventing stress cracking in polyethylene terephthalate beverage containers during bottling operations during which the bottle is contacted with aqueous and non-aqueous materials such as cleaners and lubricants that can interact with the polyester to cause stress cracking particularly in the container base. A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.

Abstract:
An engine lubricant formulated as a complete crankcase motor oil or additive concentrate composed of a combination of chemical constituents including a base oil selected from a synthetic oil, a mineral oil or semi-synthetic base oil (hydrogenated oil) or combination thereof, an oil soluble molybdenum additive, a dispersant inhibitor containing zinc dithiophosphate, and viscosity index improvers and one or more seal swelling agents to lubricate the engine and recondition the seals of new and/or high mileage engines. Addition of a polyalphaolefin and/or one or more esters such as a diester or polyolester may also be utilized therein. The lubricant may be formulated as a complete engine oil crankcase lubricant, or concentrated into an additive for addition to conventional mineral oil based engine oil, synthetic engine oils, or blends thereof in an effective amount of up to 30 percent volume percent, typically from 20 to 25 percent by volume.
Abstract:
A lubricant composition for use in a rotary vane compressor has a base oil component that comprises an alkylbenzene as a major component thereof and a polyol ester as a minor component thereof. In particular, the base oil component comprises at least 55% by weight of alkylbenzene and at most 45% by weight of a polyol ester, more preferably between 55% and 75% by weight of alkylbenzene and between 45% and 25% by weight of polyol ester and, especially, between 60% and 75% by weight of alkyl benzene and between 45% and 25% by weight of polyol ester.

Abstract:
This invention describes a refrigerating oil composition for natural substance-based refrigerants which comprises (A) a synthetic oil component comprising a polyether compound having a pour point of −10° C. or lower and (B) a mineral oil component comprising sulfur components, wherein the ratio of amounts by weight of component (A) to component (B) is in the range of 25:75 to 99:1 and the amount of the sulfur components derived from component (B) in the composition is in the range of 5 to 1,000 ppm. The refrigerating oil composition has excellent miscibility with natural substance-based refrigerants and, in particular, with ammonia-based refrigerants, exhibits an improved lubricity and used for industrial refrigerators using natural substance-based refrigerants such as ammonia, propane, butane and carbon dioxide.
