Silicone grease, sometimes called dielectric grease, is a waterproof grease made by combining a silicone oil with a thickener. Most commonly, the silicone oil is polydimethylsiloxane (PDMS) and the thickener is amorphous fumed silica. Using this formulation, silicone grease is a translucent white viscous paste, with exact properties dependent ...
Pipe dopes used in oil drilling frequently include powdered graphite, lead and zinc, and sometimes copper suspended in grease. In the past, nickel, talc, silica, calcium carbonate and clay have been included. Heavy metals make up to 25% of the volume of the dope. Silicone is included to improve application to wet or cold surfaces. [7] [8]
Two typical examples: Left - Krytox, a fluoroether-based grease; Right - a silicone-based high vacuum grease by Dow Corning. Apiezon, silicone-based, and fluoroether-based greases are all used commonly in laboratories for lubricating stopcocks and ground glass joints. The grease helps to prevent joints from "freezing", as well as ensuring high ...
The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field.
The noise can be alleviated using specialty coatings that are applied at the time of manufacture of the seal. Such coatings can also improve the chemical resistance of EPDM rubber. Some vehicle manufacturers also recommend a light application of silicone dielectric grease to weatherstrip to reduce noise [citation needed].
The thermal grease 860 is a silicone oil with a Zinc Oxide filler and 8616 and 8617 are synthetic oils with various fillers including Aluminum Oxide and Boron Nitride. At 25 °C the densities are 2.40, 2.69 and 1.96 g/mL for the greases 860, 8616 and 8617 respectively. Helium II
Silicone oil serves as an effective gun lubricant, suitable for use with the rubber, plastic, and metal components commonly found in firearms. Its high surface adhesion allows it to create a long-lasting protective film, which is beneficial for preserving guns during prolonged storage.
Regarding use of silicone grease on rotating contact. This is NOT an appropriate use for three reasons. a) As the author of the comment noted, the lubricating qualities of silicone grease may be insufficient. and b) rotating contacts may experience arcing at times. Silicone may convert to silicon carbide in the presence of electrical arcing.
