Difference between Dielectric Grease and Silicone Grease

When working with electrical equipment, it’s important to use the right type of grease. Dielectric grease and silicone grease are two popular types of grease, but what’s the difference between them? In this post, we’ll take a look at the key differences between dielectric grease and silicone grease, so you can choose the right one for your needs.

What is Dielectric Grease?

Dielectric grease is an electrically insulating compound that is used to protect electrical connections from corrosion. It is often used on connectors and terminals, where it helps to prevent oxidation and pitting. Dielectric grease can also be used to lubricate moving parts, such as slide switches and relays. In addition, it can be used to seal electrical enclosures and prevent moisture infiltration. Dielectric grease is available in a variety of formulations, each designed for specific applications. However, all formulations share the common goal of protecting electrical components from the harmful effects of moisture and corrosion. Thanks to its versatile nature, dielectric grease is an essential tool for anyone who works with electrical systems.

What is Silicone Grease?

Silicone grease is a type of synthetic oil that is made up of silicone polymers. It is clear, odorless, and non-toxic. Silicone grease is used in a variety of applications, including lubricating door hinges, electrical connections, and O-rings. It can also be used to waterproof electronic components and prevent corrosion. Silicone grease is an excellent choice for applications that require a high degree of heat resistance. It can also withstand extreme cold and has excellent dielectric properties. While silicone grease does have many advantages, it is not suitable for all applications. For example, it should not be used on painted surfaces or plastics as it can cause staining. In addition, silicone grease should not be used on bearings or other moving parts as it can gum up the works. Overall, silicone grease is a versatile product that has many uses. When selecting silicone grease, it is important to choose one that is specifically designed for the application at hand.

Difference between Dielectric Grease and Silicone Grease

When it comes to choosing grease for electrical applications, there are two main choices: dielectric grease and silicone grease. Both of these options have their own advantages and disadvantages, so it’s important to choose the right one for the job at hand. Dielectric grease is made from a base of petroleum jelly or mineral oil, and it is thickened with zinc oxide. This type of grease is excellent at protecting against corrosion, and it also has good insulating properties. However, dielectric grease can harden over time, making it less effective at lubrication. In addition, it is not as resistant to high temperatures as silicone grease. Silicone grease, on the other hand, is made from a base of silicone oil. It has excellent lubricating properties and can withstand high temperatures without breaking down. However, silicone grease is not as effective at protecting against corrosion as dielectric grease. In addition, it can be difficult to remove from surfaces once it has been applied.


Dielectric grease and silicone grease are both lubricants used in electrical equipment. However, they have different properties that make them more or less suitable for certain applications. Dielectric grease is a non-conductive material that protects electrical insulation from moisture and corrosion. Silicone grease is a conductive material that dissipates heat and prevents metal-on-metal contact. Both greases have their place in electrical equipment, but it’s important to understand the difference between them so you can choose the right one for the job.
