摘要： A continuous process for producing a polyurea concentrate or powder. The process includes combing at least one amine and an isocayante in the presence of a liquid diluent or a base oil in a rotor stator mixer. The concentrate comprises a polyurea in a base oil wherein the concentration of from about 20 weight percent to about 50, or 40 or 35 or 30 weight percent of polyurea based on total weight of grease thickener. The powder has particle size of 2 to 400 microns. This concentrate or powder can then be formulated by grease manufacturers to the desired final properties without the need for handling of the isocyanate and amine raw materials.

摘要： The present disclosure relates to a lubricant composition including a base oil, a thickener and a thickener supplement, and a method of manufacturing the same. The lubricant composition of the present disclosure is effective at improving performance at high-temperature by maintaining the evaporation amount and friction characteristics even at high temperatures, thus inhibiting oil contamination of powertrain parts and the like and maintaining sticking phenomenon even in a high-temperature environment, thereby increasing the durability of parts.

摘要： The present invention addresses a problem of providing a grease composition containing a urea-based thickener and capable of appropriately maintaining the kinematic friction force in lubrication parts. The grease composition contains a base oil (A) and a urea-based thickener (B), wherein the base oil (A) has a kinematic viscosity at 40° C. of 100 mm2/s or more, and the particles containing the urea-based thickener (B) in the grease composition satisfy the following requirement (I). Requirement (I): the area-based arithmetic average particle diameter of the particles is 2.0 μm or less, as measured by a laser diffraction/scattering method.

摘要： Effects of Oxygen on grease or another organic paste product can be evaluated with a modified version of the ASTM D942 test methodology for oxidation stability of lubricating greases or other organic paste products by employment of an oxidation pressure vessel, in which at least one of (A) a very small sample of the grease or other organic paste product is deployed for testing within the oxidation pressure vessel such that the sample has an enhanced surface area to mass ratio, and (B) a temperature other than about 99° C. is employed during the testing. In general, the testing is carried out under oxidation pressure conditions. The sample may be evaluated with respect to Oxygen uptake. Additional technique(s) directed to oxidation and/or other properties of the sample may be carried out before to after any Oxygen uptake evaluation, for example, FTIR analysis and/or ATR-FTIR analysis.

摘要： A hybrid grease is provided having low coefficients of friction and high wear protection which is employable over a wide temperature range. The hybrid grease includes a combination of a grease based on a silicone oil in conjunction with a grease based on synthetic hydrocarbon oils, mineral oils or polyglycols. The hybrid grease may especially be used to lubricate joints in vehicle parts based on plastic-steel pairings.

摘要： The incorporation of highly refined, low viscosity index base oils along with a polymeric thickener produces a final readily biodegradable fluid with a significantly high viscosity. The present invention allows the formulation of a high viscosity readily biodegradable fluid where the vast majority of the fluid is mineral oil. Previous uses of mineral oils only allowed for formulation of substantially lower viscosity readily biodegradable fluids.

摘要： A grease composition contains a mixture of a lubricating base oil, an ester-terminated polyamide and at least one polyolefin. The ester-terminated polyamide has the formula: R1-O—CO—R2-CO—[NH—R3-NH—CO—R2-CO]n-O—R1. R1 contains 4-22 carbon atoms, R2 contains 4-42 carbon atoms, R3 contains 2-9 carbon atoms and n is an integer in the range of 1-20. The grease composition can be used for lubricating a mechanical component having a metal surface and/or for protecting a mechanical component having a metal surface against corrosion, wear and/or fretting.

摘要： A bicycle chain lubricant that may be applied as a coating on a bicycle chain is a crystalline solid at ambient temperatures, yet when the chain is in motion the forces around internal components locally transforms the coating to a lubricous fluid. This increases chain efficiency in the drive train and reduces ware by limiting water and dirt access to chain internal components.
