In the conditions of modern industry and heavy engineering, it is critical to choose the right consumables that can withstand extreme loads. One of these materials is TomFlon MPM-70 Multifunctional plastic lubricant designed to work in friction nodes with high speeds and temperatures. Its unique formula allows it to maintain its working properties where traditional lithium or calcium compounds are rapidly destroyed and leaked.
The basis of this product is a synthetic base oil thickened with a complex of aluminum soap, which gives it specific rheological properties. It is not just a thick substance, but a high-tech engineering material that forms a stable protective film on metal surfaces. Use of the TomFlon MPM-70 allows to significantly extend the life of bearing units and reduce the frequency of equipment maintenance.
When choosing a lubricant for the responsible mechanisms, it is necessary to take into account not only the temperature range, but also the chemical resistance of the composition. TomFlon MMM-70 has exceptional resistance to oxidation even during prolonged heating, which prevents the formation of solid deposits and lacquer films inside bearings. This makes the product indispensable for the maintenance of electric motors, fans and other equipment operating in aggressive environments.
Chemical composition and physical properties
The fundamental difference between the product in question and its analogues is the use of a thickener based on complex aluminum soap. Unlike lithium analogues, aluminum complexes provide higher temperature stability and better water resistance. Basic oil in the composition TomFlon MPM-70 selected in such a way as to minimize evaporation during heating and maintain viscosity at low temperatures.
Visually, the lubricant is a homogeneous mass of light beige or white color, which facilitates visual monitoring of its condition in the friction node. The presence of antioxidant and anti-wear additives allows the material to resist thermal destruction. When water enters the node of friction, the lubricant is not emulsified and is not washed away, maintaining adhesion to metal surfaces.
It is important to note that TomFlon MPM-70 It does not contain solid fillers such as graphite or molybdenum disulfide. This eliminates the risk of clogging channels of the lubrication system and allows the product to be used in high-speed bearings where the presence of solid particles could lead to abrasive wear. The mechanical stability of the composition ensures that the lubricant structure does not collapse under the action of shear loads.
⚠️ Note: Despite the high level of chemical inertia, TomFlon MPM-70 It is not recommended to mix with bentonite or organosilicon-based lubricants, as this can lead to the dissection of the mixture and loss of lubricating properties.
When switching from another type of lubricant, it is recommended to thoroughly wash the friction unit with a solvent or a small amount of base oil before laying a new portion of TomFlon MMM-70.
Temperature and thermal stability
The key parameter that determines the scope of any lubricant is its temperature range. For TomFlon MPM-70 The lower limit of efficiency is minus 40 degrees Celsius, which allows you to start the equipment in winter without prior warming up. The upper limit of short-term operation reaches plus 180 degrees, and in some modes - up to 200 degrees Celsius.
Thermal stability is ensured by strong bonds in the structure of the aluminum thickener. When heated, the lubricant does not melt and does not go into a liquid state, as happens with conventional lithium compounds. Instead, it softens slowly, remaining in the bearing work area. This property is critical for electric motors, where the body temperature can rise significantly during operation.
With prolonged exposure to high temperatures TomFlon MPM-70 does not form hard coke deposits that could block the movement of rolling bodies. Soft oxidation products are easily removed during scheduled maintenance. The low evaporation of the base oil prevents the lubricant from “thickening” during operation, ensuring stable torque throughout its lifetime.
Applications in industry and mechanical engineering
Due to its unique characteristics, TomFlon MPM-70 It is widely used in various industries. First of all, it is energy and metallurgy, where the equipment operates under conditions of high thermal loads. The lubricant is ideal for bearings of electric motors operating in continuous mode, as well as for friction units of fans of smoke blowers and blowing machines.
In the chemical industry, the product is used to lubricate mechanisms that come into contact with water vapor and weak acids. High water resistance allows the application TomFlon MPM-70 in paper production and food industry enterprises, where frequent washing of equipment is required. The lubricant is not washed away by a stream of water and protects the metal from corrosion.
The list of main sites where the use of this material is recommended includes:
- 🏭 Bearings of electric motors of alternating and direct current, operating at high speeds of rotation.
- 🔧 hinges and guides of industrial equipment exposed to heat and moisture.
- ⚙️ Reductors and gears operating under variable loads and temperature fluctuations.
- 💨 Ventilation systems and turbochargers requiring low evaporability lubricants.
Use of the TomFlon MPM-70 in the listed nodes allows you to move from scheduled and preventive repairs to maintenance on the actual condition. This reduces equipment downtime and reduces lubricants consumption per year of operation.

Comparison with analogues and competitive advantages
In the lubricants market TomFlon MPM-70 It is often compared to imported analogues such as Klüber, Shell and Mobil. The main advantage of the Russian product is the optimal ratio of price and quality, as well as the availability of supplies. In terms of its physical and chemical indicators, it is not inferior to the leading world brands, and in a number of parameters, such as water resistance, it even surpasses them.
Below is a comparative table of characteristics TomFlon MPM-70 and typical general purpose lithium lubricant:
| Characteristics | TomFlon MPM-70 | Lithium lubricant (Litol-24) | Unit of measurement |
|---|---|---|---|
| Drop temperature | min. 260 | min. 180. | °C |
| Operating temperature range | -40...+180 | -20...+120 | °C |
| Penetration (60 double bars) | 265-295 | 265-295 | 0.1 mm |
| Washability with water (at 38°C) | less than 5% | 20% | % |
As you can see from the table, TomFlon MPM-70 It can withstand much higher temperatures without losing structure. This makes it a preferred choice for upgrading equipment previously operated on less resistant lubricants. Switching to this product often eliminates problems with lubrication leakage and frequent addition of material.
⚠️ Note: When replacing lubricant in high-loaded nodes, make sure the new material is compatible with seals. Thought TomFlon MPM-70 Safe for most rubber seals, checking compatibility with a specific type of rubber will not be superfluous.
Instructions for proper application and replacement
To ensure maximum efficiency of the lubricant, it is necessary to strictly observe the technology of its application. The process begins with the preparation of the friction unit: the old lubricant should be completely removed, and the surfaces cleaned of wear and dirt products. Use of the TomFlon MPM-70 Overlapping incompatible materials can lead to unpredictable consequences.
When laying lubricant in the bearing, it is recommended to fill from 30% to 50% of the free volume of the bearing and up to 70% of the body volume. Excess lubrication can cause the node to overheat due to foaming and stirring of mass when rotating. For application, it is convenient to use a syringe bar or automatic lubrication systems tuned to the appropriate viscosity.
The sequence of actions when replacing the lubricant is as follows:
- Stop the equipment and let it cool to a safe temperature.
- Clean the oil presses and lubrication channels of dirt.
- Squeeze the old lubricant until fresh portions appear or wash the node with solvent.
- Fill the bearing with a new portion TomFlon MPM-70Evenly spreading it over the working surfaces.
- Run the equipment at idle for lubrication distribution.
What to do if the grease is darkened?
Darkening of TomFlon grease MMM-70 during operation is a normal process and indicates the work of antioxidant additives. If the consistency remains uniform and there are no signs of stratification, no urgent replacement is required.
