Plumbers Grease - Not for use on rubber or synthetic O-rings. stearate. For applications involving highly reactive substances, powdered polytetrafluorethylene (PTFE) is the thickener.[1] Black Swan Plumbers Grease is a special combination of lithium soaps, solvent refined base stocks and additives. Formulated for many plumbing applications. Makes hard turning faucets work smoothly. Lubricates stems of faucets, valves, ballcocks etc. Waterproof, Because of the components. More specialized silicone greases are made from fluorinated silicones or, for low temperature applications, PDMS containing some phenyl substituents in place of methyl groups.
For food applications, the thickener is amorphous fumed silica. Using this formulation, silicone grease is a translucent white viscous paste, with exact properties dependent on the type and proportion of the special additives, the metal parts are also protected against rust, oxidation and corrosion. Will not melt like ordinary grease. Temperature range use from -20°F to 250°F. Not for use on rubber or synthetic O-rings. Using this formulation, silicone grease is a translucent white viscous paste, with exact properties dependent on the type and proportion of the components.
