Abstract:
The invention relates to lubricating grease compositions comprising (a) at least one highly viscous, fluorinated oil having a viscosity of between 500 - 1500mm 2 /s, (b) boron nitride and (c) a binder which is selected from bentonite, alkali metal phosphates, aluminum phosphates, alkali metal silicates, alkaline earth metal silicates, aluminum silicates, alkaline earth metal carbonates, calcium borate, silicon dioxide, titanium dioxide, aluminum oxide and mixtures thereof. Said lubricating grease compositions can be used, in particular, in a high-temperature range, for example for greasing oven drawer rails.
Abstract:
The invention relates to the use of ionic fluids for the production of water-resistant lubricating grease compositions, which are employed in a temperature range of at least -30°C to at least 180°C and have good anti-corrosion properties.

Abstract:
An article including a first release liner with a first release surface, a second release liner with a second release surface, and a layer of a thermally conductive grease between the first and the second release surfaces. The thermally conductive grease includes a mixture of at least three distributions of thermally conductive particles, each of the at least three distributions of thermally conductive particles having an average (D50) particle size which differs from the other distributions by at least a factor of 5.

Utilisation pour joints homocinétiques des transmissions de véhicules automobiles.
Abstract:
A method for the preparation of carbon nanotube modified fluids such, that the dispersion of nanotubes in such fluids, exampled by those which are oil based is enhanced through the combined use of mechanical, sonic and ultrasonic devices.
Abstract:
The present disclosure relates to greases containing metal sulfonate thickeners. In one example the thickener may be a calcium sulfonate thickener. In other examples grease may contain a combination of a metal sulfonate thickener and another thickener, such as a metal complex soap grease, detergent, or non-soap thickener. The grease may be formulated to meet specific performance criteria relevant to lubrication of a roller cone drill bit in downhole conditions. The disclosure also relates to a roller cone drill bit containing a grease of the disclosure.
