Hot Selling Equivalent-to PFPE Grease

Perfluoropolyether lubricant is a synthetic lubricant with good temperature, corrosion and chemical resistance, mainly used for oil film lubrication of machinery under high temperature, high load, strong acid, strong alkali and strong oxidizing agent environment, such as turbocharger, vacuum pump and high temperature furnace.


Perfluoropolyether lubricant is usually difficult to dissolve in conventional organic solvents, including petroleum ether, benzene, toluene, acetone, ethyl acetate and so on. However, it can be dissolved by strong solvents such as benzene nitrate, trichloroethylene and chloroform. In practice, perfluoropolyether lubricants usually do not need to be dissolved and can be used directly.


Note: When handling PFPE lubricants, contact with oxygen, gaseous forms of chloride ions and fluoride should be avoided to avoid explosion or toxic gas release.


The molecular structure of PFPE lubricants and hydrocarbon lubricants is basically similar, but in the PFPE molecule the fluorine atom replaces the hydrogen atom, thus replacing the c-H bond in hydrocarbons with the stronger c-F bond. And the existence of c-o and c-c strong covalent bonds, as well as the characteristics of PFPE molecular neutrality, so that PFPE has a high thermal and oxidative stability and good chemical inertia and insulation properties. The larger molecular weight PFPE also has low volatility, a wide liquid temperature range and excellent viscosity-temperature characteristics. In addition, the key physicochemical properties of PFPE polymers include: detection stability, biological inertness, low surface energy, good lubricity and compatibility with plastics, metals and elastomers.


Properties of perfluoropolyethers


The main chain of perfluoropolyether is composed of -CF2-O-CF2- such ether chain, different from -CF2CF2CF2- perfluoroolefin chain, it has the flexural property, the The glass transition temperature is low, and the temperature range of the co-liquid (freezing point to boiling point) is extremely wide. On the other hand, due to the strong electron-absorbing effect of elemental fluorine, the polymer does not exhibit etheric properties, so it has excellent heat resistance, chemical stability, oxidative stability and complete noncombustibility.


However, this substance lacks hygroscopicity and is insoluble in organic solvents, and is only miscible in perfluoro oil or Fluoron 113 (tri-atmosphere trifluoroethane). This property makes it virtually harmless to plastics and rubber.





Perfluoropolyether has a high specific gravity but low surface tension and refractive index, possessing the characteristics of perfluorinated compounds, and is a highly transparent oil substance. It has a very high LD56 value in an oral acute toxicity test on mice and has no accumulation in living organisms, so it is almost non-toxic. However, when decomposition occurs, extremely toxic substances are produced. When using in an environment where decomposition is expected to occur, it is necessary to install air-ventilating equipment and not to take this fluorine oil lightly because it is stable.

Perfluoropolyether grease has excellent high temperature resistance, chemical corrosion resistance and wear resistance, and is often used in extreme environments (such as aerospace, semiconductor equipment, precision instruments, etc.). However, if it is found to be too viscous during use, it may affect the lubrication effect or equipment operation. The following is a detailed analysis and treatment method for its "too sticky" problem:


Analysis of the reasons for excessive viscosity
1. Improper selection of base oil viscosity: The viscosity of perfluoropolyether grease is determined by the viscosity of the base oil (perfluoropolyether). If the viscosity grade of the selected base oil is too high (such as ISO viscosity grade greater than 460), it will show obvious stickiness at room temperature.
2. Excessive thickener content: The content of thickener (such as polytetrafluoroethylene PTFE) in the grease is too high, which will increase the overall viscosity (such as NLGI grade exceeding No. 2), and thus appear more viscous.
3. The operating temperature is too low: The optimal operating temperature of perfluoropolyether grease is usually -20℃~260℃. If the ambient temperature is lower than its applicable lower limit, the fluidity of the base oil decreases, which will cause the grease to thicken.
4. Contamination or deterioration: After the grease comes into contact with water, dust or chemical media, the structure may change, resulting in an abnormal increase in viscosity.

Specific treatment methods
1. Adjust the use environment or increase the temperature under working conditions: If the viscosity is caused by low temperature, the grease can be restored to fluidity by preheating the equipment or increasing the ambient temperature. Reduce the load or speed: High-viscosity grease may increase friction under high-speed or heavy-load conditions. The operating intensity of the equipment can be temporarily reduced to observe whether the viscosity affects the performance.
2. Dilution treatment (caution required) Use special diluent: Perfluoropolyether grease needs to be diluted with fluorinated solvents, and avoid using ordinary organic solvents (such as ethanol, acetone) to prevent damage to the grease structure. Note: Dilution may shorten the lubrication life of the grease. It is only suitable for temporary adjustments, and it is recommended to operate under the guidance of professionals.
3. Replace the appropriate type of grease to reduce the viscosity of the base oil: choose a perfluoropolyether grease with a lower viscosity grade. Adjust the consistency grade: reduce the NLGI grade from No. 2 to No. 1 or No. 0, the consistency is softer and the fluidity is better. Consult the supplier: provide the equipment operating conditions (temperature, load, speed) and the existing grease model, and professionals will recommend the appropriate product.

Precautions
Avoid mixing: Mixing perfluoropolyether grease with other types of grease (such as lithium-based grease and silicone-based grease) may cause structural damage and aggravate the viscosity problem.
Safety protection: Wear gloves and protective tools during operation and operate in a well-ventilated environment.
Performance test: After any adjustment, the fluidity, lubrication effect and equipment operating temperature of the grease must be tested on a small range of equipment first, and then fully applied after confirming that there is no abnormality.

In the daily operation and maintenance of the heat setting machine, there is a key link that is often overlooked, but it plays a decisive role in the overall performance of the equipment, that is, the choice of bearing grease. Choosing the right grease can not only extend the service life of the equipment and reduce maintenance costs, but also ensure the efficiency and stability of production. If you choose the wrong one, you will be in big trouble.

There are many types of heat setting machine bearing grease on the market, which is dazzling. Among them, grease made of silicone oil was once very popular because it does have a certain high temperature resistance. But in actual use, there are many problems. In the high temperature environment of the heat setting machine, silicone oil grease will produce a lot of carbon deposits. These carbon deposits adhere to the inside of the equipment, like a layer of insulation, which seriously affects the heat conduction efficiency, makes the equipment "uncomfortable", and greatly reduces the performance. Moreover, cleaning carbon deposits is a dirty and tiring job, which takes a lot of time and energy, the equipment downtime becomes longer, and the maintenance cost rises sharply, which is really not worth the loss. Ordinary synthetic grease is not much better. Although the price is relatively affordable, it has a short service life and is also prone to carbon deposits at high temperatures, which cannot meet the demanding requirements of long-term stable operation of the heat setting machine. Frequent replacement of grease not only increases the maintenance workload, but may also cause bearing wear and equipment failure due to insufficient lubrication.


So, is there a perfect solution? The answer is yes, that is perfluoropolyether grease. With its excellent high-temperature stability, it has become the only choice for heat setting machine bearing lubrication. Under the high-temperature working conditions of the heat setting machine, perfluoropolyether grease can remain stable, will not decompose, volatilize, and will not produce carbon deposits. This means that it can provide continuous and reliable lubrication protection for bearings, greatly extend the service life of bearings, reduce the risk of equipment failure and downtime, and save a lot of costs for enterprises in the long run.

During a conversation with Factory Manager Zhang, a Jialede sales manager learned that one of his factory's PCB baking tunnel ovens was experiencing chain lubrication issues. The manager recommended the company's YBS-1103 perfluoropolyether oil. The equipment uses three rows of large roller chains and operates in a high-temperature environment of 80°C. Zhang previously faced numerous issues using liquid lubricants:

The machine's automatic lubricator struggled to accurately control the amount of oil injected.


The oil easily leaked onto the floor, causing waste and pollution.


The lubricant had specific requirements: low volatility and long-lasting lubrication, requiring no re-lubrication for six months to a year. Furthermore, the company sought to avoid dust generation from drying solid lubricants or rapid drying of liquid lubricants.

After a detailed discussion with laboratory technicians, the Jialede product manager and laboratory technicians, considering the customer's equipment operating conditions—consistent operation at 80°C, demanding chain lubrication, low volatility requirements, and long lubrication intervals—decided to recommend YBS-1103 perfluoropolyether lubricant. Laboratory validation data showed that YBS-1103 fully met the technical requirements for this application scenario. Factory Manager Zhang, upon repurchasing the product, stated that it not only met the performance requirements for low volatility and long-lasting lubrication, but also effectively reduced lubricant loss for the factory, truly achieving cost reduction and increased efficiency.


The Jialede team, leveraging its extensive experience, provided Factory Manager Zhang with an efficient and reliable lubrication solution precisely tailored to the client's needs through a single phone call and combined with laboratory test data. To date, Jialede has successfully solved fluorine chemical application challenges for 5,879 companies, achieving its service goal of "one-time success" through professional selection advice.
