McLube offers molybdenum disulfide (MoS2) and polytetrafluoroethylene (Teflon®) powder lubricants for assembly, compounding, and tumbling. 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 (Teflon®) powders are commonly used as compounding lubricants to add inherent lubricity to a given material.

About MoS2 Powders

Molybdenum disulfide (MoS2) powders can be used for compounding and tumble lubrication or combined with a binder to form a dry-film coating. Moly powders can also be dispersed in oils and greases or in composites of metal, plastic and rubber. The lubricating properties of MoS2 are a result of its familiar crystal structure which allows for shearing and creates a low coefficient of friction. McLube MoS2 –98, McLube MoS2-99 and McLube MoS2-100 differ only in particle size. McLube Technical Representatives can provide assistance when selecting the optimal particle size for your application.

Applications for MoS2 Powder Lubricants

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 – Teflon Powder Lubricant

Polytetrafluoroethylene, also known as PTFE or Teflon ®, is a low-molecular-weight polymer with excellent lubricating and anti-sticking 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.
