Electrically Insulating Grease


Single-Use Packet	Tube	Grease Gun Cartridge	Jar

Also known as dielectric grease, use insulating grease to lubricate and protect electrical systems. It resists water and corrosion. This grease can be used on most rubber and plastic.

Grease lubricates most efficiently below the maximum temperature.

Molykote 5 Compound—Molykote 5 Compound is for use on insulators, bushings, and high-current switches.

1 NLGI Grade—NLGI 1 is about the consistency of tomato paste.

2 NLGI Grade—NLGI 2 is about the consistency of peanut butter.

3 NLGI Grade—NLGI 3 is about the consistency of vegetable shortening.

Nonmelting—Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.

Dielectric Strength—Dielectric strength measures the maximum voltage a grease can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.

A high silver content gives this grease excellent conductivity for applications where electricity and heat transfer are required. It is suitable for ESD (electrostatic discharge) and EMI (electromagnetic interference) shielding applications.

Grease lubricates most efficiently within the listed temperature range.

2 NLGI Grade—NLGI 2 is about the consistency of peanut butter.

Melting Temperature—Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

Electrical Resistivity—Electrical resistivity is a measure of how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.

Thermal Conductivity—Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.

Cannot Be Sold To—Product regulations restrict sales to the listed jurisdictions/areas.
