Powdered Lubricants

Powdered Lubricants

McLube offers molybdenum disulfide (MoS2) and polytetrafluoroethylene (PTFE) powders for assembly, compounding, and tumble lubrication. While generally cleaner and easier to work with than powder, lubricant dispersions are not ideal for some applications. Moly Powders may be used during forging operations, stone processing, drilling, tumbling operations, or as insertion aids for smaller parts and threaded connectors. PTFE powders are commonly used as compounding lubricants to add inherent lubricity to a given material. Explore below for more information or contact McLube for technical assistance with powdered lubrication.

Molybdenum Disulfide Powders (MoS2)

Molybdenum Disulfide Powders (MoS2) may be used as a dusting lubricant or compounded into various metals, plastics, and rubbers to create inherent lubricity during or after production. MoS2 powders flatten out and burnish very well into any surface, sealing the microporosities that cause friction. McLube offers three MoS2 powders with varying particle sizes: Technical Fine, Technical Grade, and Super Fine Grade. Contact McLube and one of our technical representatives will help you select the appropriate MoS2 grade for your application.

Common Applications

Rubber, plastic, some composites, metallurgical additives in steel, rubber self-lubrication, forging, drilling, threaded connectors, bolts, nuts, pins, watch gears, industrial load-bearing gears, etc.

Polytetrafluoroethylene Powders (PTFE)

Polytetrafluoroethylene (PTFE) is a low molecular weight polymer with excellent lubricating and anti-stick properties. PTFE, commonly referred to as Teflon®, is an extremely versatile lubricant with applications ranging from frying-pan coatings to industrial release agents. McLube supplies high-quality PTFE Powders for use as lubricants or additives in polymers, rubber, polyurethanes, paint, and oils. Compounding PTFE into certain materials will create inherent, self-lubricating properties that facilitate processing of tacky materials or add a degree of slip to finished products. PTFE may also be employed as a powdered lubricant or purchased for in-house dispersion into a liquid base. Contact McLube for more information and complimentary samples of our powdered lubricants.
