A lot of substances used in factories come in different forms. There can be insulators, instant protectors or moistening agents.

Such substances are also found to be used at home too. Factory insulation tapes are also used at home to insulate electrical wires.

Similarly, two types of industry-oriented substances play a crucial role in small machinery or equipment that are of prime importance on a larger scale.

The two most prominent substances used in factories are Dielectric Grease and Vaseline. Though they have extensive usage in the factories, they have different usages altogether.

Key Takeaways

  1. Dielectric grease is a non-conductive silicone-based compound that protects and seals electrical connections from moisture, dirt, and corrosion.
  2. Vaseline is a brand of petroleum jelly, a semi-solid mixture of hydrocarbons, commonly used as a moisturizer or lubricant in various applications.
  3. Dielectric grease and Vaseline serve different purposes, with dielectric grease being specifically designed for electrical applications, while Vaseline is more suited for general use.

Dielectric Grease vs Vaseline

Dielectric grease is a non-conductive material used to protect electrical connections from moisture, corrosion, and oxidation and is known for its high-temperature resistance and consistency. Vaseline is a general-purpose lubricant but can cause electrical shorts if applied to electrical connections.

What is Dielectric Grease?

Dielectric Grease is a powerful corrosion resistance grease that protects the equipment and wirings from moisture and other dust substances. It is widely used in many industrial applications as well as household applications.

Dielectric grease is primarily insoluble in water, thus making it widely used in underwater types of machinery too. They have the highest melting point; hence it has a powerful preservation strength.

The most common usage of dielectric grease is found in spark plug wires and electrical connectors for lubricating purposes. A point of caution is to be taken while using dielectric grease; it is not a good conductor of electricity, so it must be used sparingly and strategically while using electric connections.

Further, it is made out of silicone and also called silicone grease; it is not advised to use it in silicone-based rubbers or even plastics. It may cause the grease to break over time due to chemical reactions.

The applying methods of dielectric grease must follow a particular strategy. While applying, apply it sparingly on the rubber boot and evenly so that it does not touch the adjacent iron or electric components.

It will cause a high-voltage current to pass through seamlessly. At the same time, it also helps the high voltage current to leak inside the rubber. Thus preventing any damage too.

The grease can also play a formidable role in applying it in the roller gaskets. It can be used in the metal equipment’s exteriors that serve as connectors for seamless functionality and avoids corrosion.


What is Vaseline?

Vaseline, or Petroleum Jelly, is widely used in lubrication. It has a moistening feature that makes this possible.

Petroleum jelly has a low melting point. Thus, using it in places exposed to high temperatures is not advisable. Further, Petroleum jelly has good electrical conduction properties that can be used widely in electrical applications.

Vaseline is mainly used in beauty care and is prominent in industrial applications. It is extensively used to protect metals and is an excellent lubricating agent.

It has unique properties make businesses use this in the pharmaceutical and food preparation industry. This does not react readily with any chemicals used in such endeavours.

Considered chemically inert, it has less preservation strength too. Yes, it is also insoluble in water, hence can be used in Wet environments too.

Petroleum Jelly is used in many ointment preparations worldwide. It also acts as a protective substance as a coat to the ointments. At the same time, they are chemically used as a substitute for many of the fat substances in the cosmetic industry.

Petroleum jelly is used in mass because of its price and ease to use the property.


Main Differences Between Dielectric Grease and Vaseline

  1. The main difference between Dielectric Grease and Vaseline is the preservation strength of Dielectric Strength is more when compared to Vaseline.
  2. Dielectric Grease is widely used in industrial applications and does not find any use in domestic cosmetics, while Vaseline is commonly used in manufacturing decorative items.
  3. Dielectric Grease has a very high melting point, whereas Vaseline has a shallow melting point, making it unsuitable for use at high temperatures.
  4. Both the Dielectric grease and Vaseline are insoluble in water, but the former is not a good conductor of electricity while the latter is a good conductor.
  5. The price of the dielectric grease is higher compared to Vaseline.
