About Grease

About Lubricants

Highly pure and with no additives to contaminate sensitive environments, use this grease in clean rooms and electronic assembly workstations. It is nonconductive, chemically inert, and can withstand extreme temperature swings. This long-lasting grease also has an indefinite shelf life.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter.

Grease lubricates most efficiently within the listed temperature range. Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.

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. 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 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 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.

DuPont Molykote 4 Electrical Insulating Compound also acts as a moisture barrier.

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

Dry-Film Lubricants

These lubricants go on wet for easy application. Once dry, they form a nonstick film that won't attract dust. Use them for general purpose lubricating in most applications.

Lubricants with boron nitride and ceramic are often used in extreme-temperature applications, such as welding, metal processing, and glassmaking. Dilute 1-gallon pail with water before using.

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 and electrically conductive.
