High-Performance Friction Modifiers – MSAIL® Organic Molybdenum & FMET® Ashless Series

UNPChemicals is a professional lubricant additives manufacturer in China, providing a full portfolio of high-performance friction modifiers under our MSAIL® (organic molybdenum type) and FMET® (ashless type) brands. Our products serve as cost-effective, drop-in alternatives to equivalent grades from ADEKA and Vanderbilt.

Oil-Soluble Organic Molybdenum Friction Modifiers (MSAIL® Series)

Oil-soluble organic molybdenum additives deliver exceptional friction and wear reduction, and are core components for improving equipment energy efficiency and reducing operating consumption.

Under boundary lubrication conditions — such as engine startup and heavy-load operation — organomolybdenum compounds undergo tribochemical reactions with metal surfaces during frictional contact to form a layered protective film. With extremely low shear strength, this film converts direct metal-on-metal sliding into low-resistance interlayer sliding, significantly lowering the coefficient of friction (CoF) and mitigating surface wear.

This series is widely formulated into high-grade automotive engine oils, industrial lubricating greases, gear oils, and automotive aftermarket maintenance formulations.

Ashless Friction Modifiers (FMET® Series)

Our FMET® ashless friction modifiers form a uniform lubricating film through directional molecular adsorption on metal surfaces, without introducing phosphorus, sulfur or ash-forming elements. They feature stable friction performance and excellent compatibility with all major base oil systems, making them ideal for low-SAPS engine oils, ashless hydraulic fluids and high-performance industrial lubricant formulations.

What is Lubricant friction modifier?

Lubricant friction modifiers are chemical additives used in lubricants, oils, and greases to improve their performance by reducing friction and wear. By minimizing the friction between moving parts, lubricant friction modifiers can extend the service life of components, reduce energy consumption, lower operating temperatures, and improve overall system efficiency.

Types of Lubricant Friction Modifiers

Lubricant friction modifiers can be classified into several categories based on their chemical composition:

Organic Compounds: Derived from animal or vegetable sources, examples include fatty acids, amides, and esters such as stearic acid, oleic acid, and glycerol monostearate. These compounds form a thin, low-shear film between contacting surfaces, reducing metal-to-metal contact and lowering friction.

Polymers: Examples include polyalkylene glycol (PAG), polytetrafluoroethylene (PTFE, also known as Teflon), and poly-alpha-olefin (PAO). These polymers can form a brush-like layer between surfaces, reducing the shearing forces and minimizing wear.

Solid Particles: Solid particles such as graphite, molybdenum disulfide (MoS2), and tungsten disulfide (WS2) can be used as lubricant friction modifiers when suspended in the lubricating medium. They provide a cushioning effect, reducing friction by preventing direct contact between sliding surfaces.

Inorganic Compounds: Examples include zinc dialkyldithiophosphate (ZDDP) and molybdenum dithiocarbamate (MoDTC), which are commonly used in automotive engine oils to offer protection from wear and high-pressure conditions.

Applications of Lubricant Friction Modifiers

Lubricant friction modifiers are used in various applications across different industries:

Automotive: Engine oils, transmission fluids, and gear oils for passenger cars and commercial vehicles often contain friction modifiers to resist wear, reduce operating temperatures, and improve fuel efficiency.

Industrial: Friction modifiers are employed in industrial lubricants for gearboxes, turbines, compressors, and hydraulic systems to enhance efficiency, lower energy consumption, and lengthen maintenance intervals.

Metalworking: In metalworking fluids, cutting fluids, and drawing lubricants, friction modifiers help minimize wear and friction during machining, cutting, and forming processes, resulting in better surface finishes and reduced tool wear.

Greases: Incorporating friction modifiers into greases can enhance performance in various applications, including bearings, gears, and other mechanical assemblies, by reducing wear and friction.

Selecting Lubricant Friction Modifiers

When selecting lubricant friction modifiers for a particular application, it is essential to consider factors such as:

Compatibility with the base lubricant, other additives, and component materials.

Operating conditions, including temperature, pressure, and sliding speed.

The type and material of the contacting surfaces.

Environmental concerns, such as biodegradability and toxicity.

Careful selection and incorporation of suitable friction modifiers into lubricants can lead to significant performance enhancements in mechanical systems, offering benefits such as extended equipment life, increased efficiency, and reduced maintenance costs.
