A polymeric material mixture comprising a fluorine-containing polymer, a siloxane polymer, and at least two polymer processing additives (PPA), wherein the at least two polymer processing additives have different chemistries. For example, there can be a flexible coextruded pipe for providing a protective housing for cables, fluids, sludge or solids, the pipe comprising a pair of telescopically related inner and outer layers, where said inner layer is lubricated with the polymeric material mixture.

A low friction wear surface with a coefficient of friction in the superlubric regime under a sliding and rolling movement. The low friction wear surface includes molybdenum disulfide and graphene oxide on a first wear surface with a tribolayer formed on a rough steel counter surface during the sliding and rolling movement. Methods of producing the low friction wear surface are also provided.

A bearing material may include a polyamide-imide polymer material and a difunctional crosslinking agent comprising a hydrocarbon chain and two functional groups. The functional groups may be selected from the list: amino, acid, epoxide, thiol, isocyanate.

A coating composition for producing an article is disclosed. The coating composition includes a blend of a polymer resin and a lubricating oil, wherein the coating composition is in a liquid-phase By using the coating composition, it is possible to produce the article which can be used in various industries, only with a simple process of molding and curing a polymer resin by the technique of the prior art.

A downhole motor or pump assembly that includes a stator and a rotor rotatable within the stator. The stator includes a tubular housing and an overlay deposited by cold spray onto an interior of the housing to form overlay lobes along a first length of the stator. The downhole motor or pump may be used to perform downhole operations.

Stable, solid triamine compositions are disclosed. The pressed, cast, extruded or other solid compositions are suitable for antimicrobial, sanitizing and disinfectant applications. Ready-to-use solutions are obtained by dissolving the solid triamine compositions with water and the methods of use thereof are particularly suitable for cleaning, disinfecting, sanitizing, rinsing and/or lubricating. Beneficially, the solid triamine compositions are at least partially neutralized, allowing activity of 90% and greater of the biocidal triamine, and provide at least substantially similar or superior performance and micro efficacy to liquid formulations.

The present invention describes a pipe sealing compound/adjunct lubricant used to prevent gas or liquid leaks when applied to pipe threads and other connections of the same. The compound relies on silicone oil lubricant(s) and one or more friction modifier(s), viscosity builder(s) and filler material(s). The compound contains a viscoelastic liquid that does not have a curing phase and is resistant to hardening and/or drying. The compound is chemically resistant to a wide variety of liquids and gases, is food safe and can withstand extreme high or low temperatures and precipitous temperature fluctuations. The compound has been found to exhibit an inverse pressure to leak rate phenomena.

The present invention provides a cutting work method comprising a cutting work step of forming a through-groove passing through from a surface to a back face of a workpiece material by cutting the workpiece material with a cutting tool while bringing a lubricant material for assisting cutting process into contact with the cutting tool and/or the to-be-processed portion of the workpiece material, wherein the workpiece material comprises one or more materials selected from the group consisting of a metal, a fiber reinforced plastic, ceramic, and a composite material thereof.

A bearing assembly is disclosed that includes a first component with a first bearing surface, and a second component with a second bearing surface. A fluid is disposed between the first bearing surface and the second bearing surface supporting the first bearing surface and the second bearing surface in a non-contact rotational relationship. The first bearing surface, or the second bearing surface, or both the first bearing surface and the second bearing surface include a surface layer with solid lubricant 2D nanoparticles in a matrix.

A pre-lubricated stock sheet and a method and system for making the same are described. The pre-lubricated stock is generally in a coil wound form. The stock sheet can have opposing first and second sheet surfaces joined together by opposing side edges and opposing ends. Typically, the first and second sheet surfaces are substantially smooth and planar, wherein the sheet has 3 mg/foot.sup.2/side to about 200 mg/foot.sup.2/side of a solid lubricant having a melting temperature from about 80 to 212 degrees Fahrenheit. Moreover, the opposing side edges usually are substantially free of the solid lubricant. In some configurations, the stock sheet is an aluminum stock sheet, more particularly an aluminum can stock sheet. Furthermore, the lubricant can be in some configurations a food grade lubricant, that is qualifies a low volatile organic compound under one or more of municipal, state and federal governing authorities.
