The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricant composition comprising a water-miscible silicone material having a silicone emulsion wherein the silicone emulsion contains less than 500 ppm of a triethanolamine salts of alkyl benzene sulfonic acid compounds.

Compositions, systems and methods for introducing lubricants, and additives, that are designed to work with environmentally friendly refrigerants into vehicle heat management systems including passenger compartment air conditioning (A/C) systems are disclosed. Methods for charging lubricants and specific additives using environmentally desirable (low GWP) refrigerant or refrigerant blend compositions into an environmentally friendly system, such as a system that uses HFO-1234yf, are also disclosed.

The present invention relates to compositions in the form of silicone oil emulsions intended to be applied to curing bladders as a mould-release agent during tyre production.

A lubricant composition comprising a) a synthetic poly-alpha-olefin base fluid; b) an organomolybdenum friction modifier; c) an alkylphosphorothiolate and a hydrocarbylamine anti-wear combination; and d) a dihydrocarbyl dithiophosphate extreme pressure additive and optionally one or more of e) a copper corrosion inhibitor; f) an anti-foam agent; g) a solubilizing agent; h) polymeric viscosity index improver; and i) an oligomeric viscosity modifier is highly suitable for use in the synchronizer of a transmission.

A grease composition includes base oil, a thickener, and an organic modified polysiloxane. The base oil is an alkyl diphenyl ether. The thickener is a urea thickener, and the grease composition contains 10 to 30 mass % of the thickener based on the total amount of the base oil and the thickener. The grease composition contains 0.2 to 10 mass % of the organic modified polysiloxane based on the total amount of the base oil and the thickener.

A refrigerator oil composition may effectively suppress an increase in an acid value even when a ratio of an unsaturated fluorinated hydrocarbon compound (HFO) in a refrigerant is increased. Such a refrigerator oil composition can used for a refrigerant and may include one or more unsaturated fluorinated hydrocarbon compounds of formula (1):

C.sub.xF.sub.yH(1),

wherein x is an integer of 2 to 6, y is an integer of 1 to 11, and z is an integer of 1 to 11, and one or more carbon-carbon unsaturated bonds are present in the molecule. The refrigerator oil composition may include a base oil (A), and one or more silicone compounds (B) selected from the group consisting of an unmodified silicone (B1) and a modified silicone (B2), wherein a content of the silicone compound (B) is 0.05% by mass or more based on the total amount of the refrigerator oil composition.

The present disclosure relates to polysiloxanes, processes for preparing polysiloxanes, and hydraulic fluids comprising polysiloxanes. This disclosure also relates to hydraulic fluids comprising one or more polysiloxane compounds and diphosphonate compounds, and to the use of diphosphonate compounds in hydraulic fluids or as additives or components in various compositions, for example to provide fire retardant properties to a fluid or composition. This disclosure also relates to use of the compositions as hydraulic fluids, which may be used in various machines, vehicles and craft, including aircraft.

A method of lubricating an expandable rubber bladder is described for use during a vulcanization of a green tire within a metal press. The method can include applying compositions in the form of emulsions of silicone oils to the inner surface of the green tires and/or to the outer surface of the vulcanization bladders to facilitate the molding-demolding thereof during the manufacture of the tires.
