Grease for Electrical Contacts
Lubricate, clean, deoxidize, and prevent corrosion on electrical contacts to improve their performance.
NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter.
Grease with quartz has quartz particles to assist oxide breakup. Grease with copper has copper particles to assist oxidize breakup and resist abrasion on surfaces that require conductivity. Grease with aluminum is for use on aluminum parts that won’t come in contact with each other. Grease with graphite has graphite particles to absorb and dissipate heat. Grease with only deoxidizer provides the best lubrication and is for use on clean surfaces.
Grease lubricates most efficiently within the listed temperature range. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

Electrical-Insulating Grease
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.
NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. NLGI 2 is about the consistency of peanut butter. NLGI 3 is about the consistency of vegetable shortening.
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.
Grease lubricates most efficiently below the maximum temperature. Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.
Molykote 5 Compound is for use on insulators, bushings, and high-current switches.

Food Industry Electrical-Insulating Grease
Use this grease in areas where there is the possibility of contact with food. Also known as dielectric grease, it lubricates and protects electrical systems. It resists water and corrosion. This grease can be used on most rubber and plastic.
NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. NLGI 2 is about the consistency of peanut butter.
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.
Grease that is NSF Registered H1 and grease that meets FDA Compliant 21 CFR 178.3570 are rated for incidental contact with food. Grease that meets NSF/ANSI 51 and FDA Compliant 21 CFR 175.300 are rated for direct contact with food. Grease that meets NSF/ANSI 61 is certified for use with components that come into contact with drinking water. Grease that meets ASTM E595, a standard used by NASA, will produce almost no volatile emissions, even in a high vacuum. They’re a good choice for use around sensitive electronics.
Grease lubricates most efficiently below the maximum temperature. Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.

Heat-Transfer Foil
Made of indium, this foil is more thermally conductive than thermal interface materials (TIMs) made of plastic. By efficiently pulling heat away from components that produce heat, such as CPUs, this foil lets you use smaller forced cooling systems to extend battery life. It’s also softer and more ductile than paste and putty, covering surfaces better to minimize airflow gaps and increase heat flow. Unlike paste and grease, this foil won’t leach out from between surfaces over time, nor will it dry out and lose effectiveness. It’s clean, easy to install and reposition, and requires no surface preparation. Foil is corrosion resistant and doesn’t need special storage.
Foil with 48% tin has greater tensile and shear strength than foil without tin, but is less thermally conductive.
