2. Silicone grease - Wikipedia

   en.wikipedia.org/wiki/Silicone_grease

   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 ...

3. Grease (lubricant) - Wikipedia

   en.wikipedia.org/wiki/Grease_(lubricant)

   Grease is a solid or semisolid lubricant formed as a dispersion of thickening agents in a liquid lubricant. Grease generally consists of a soap emulsified with ...

4. Dielectric - Wikipedia

   en.wikipedia.org/wiki/Dielectric

   In electromagnetism, a dielectric (or dielectric medium) is an electrical insulator that can be polarised by an applied electric field.When a dielectric material is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor, because they have no loosely bound, or free, electrons that may drift through the material, but instead they ...

5. Polydimethylsiloxane - Wikipedia

   en.wikipedia.org/wiki/Polydimethylsiloxane

   The rubbery, vinegary-smelling silicone caulks, adhesives, and aquarium sealants are also well-known. PDMS is also used as a component in silicone grease and other silicone based lubricants, as well as in defoaming agents, mold release agents, damping fluids, heat transfer fluids, polishes, cosmetics, hair conditioners and other applications.

6. Dielectric strength - Wikipedia

   en.wikipedia.org/wiki/Dielectric_strength

   Dielectric films tend to exhibit greater dielectric strength than thicker samples of the same material. For instance, the dielectric strength of silicon dioxide films of thickness around 1 μm is about 0.5 GV/m. [3] However very thin layers (below, say, 100 nm) become partially conductive because of electron tunneling.

7. Perfluoropolyether - Wikipedia

   en.wikipedia.org/wiki/Perfluoropolyether

   The main properties of PFPE are being temperature resistant between −58 °C (215 K) and 257 °C (530 K) (depending on specific composites), having very low outgassing compared to other fluids (vapour pressure of 6 × 10 −8 Torr) and having a dielectric strength of around 15.7 MV/m.
