High-temperature fluorine-based grease, also known as perfluoropolyether (PFPE) grease, is a high-performance lubricant formulated from PFPE base oil and specific fluorinated thickeners. The molecular structure of PFPE is dominated by carbon-fluorine (C–F) bonds, which impart the grease with distinctive performance characteristics:
High-Temperature Resistance:
High-temperature fluorine-based grease remains stable under extreme temperature conditions. Its operating temperature range is broad, typically from -50°C to +250°C, and some high-end products can withstand temperatures above 300°C without oxidation, decomposition, or evaporation.
Chemical Inertness:
Due to the high electronegativity of fluorine atoms, PFPE exhibits excellent resistance to most chemicals, showing minimal reaction with acids, bases, organic solvents, or strong oxidizers. This effectively prevents degradation or failure of the grease when in contact with these media.
In modern industrial systems, the application value of high-temperature fluorine-based grease is undeniable. It is widely used in aerospace, semiconductor manufacturing, precision instruments, new energy, chemical, medical equipment, and military industries, and plays a crucial role in the following key scenarios:

With the advancement of modern industry, machinery is evolving toward high precision, high efficiency, ultra-large and ultra-small sizes, high speed, heavy load, energy saving, high reliability, and ease of maintenance. As a result, the operating temperatures of friction points in machinery are steadily increasing, placing greater demands on the high-temperature resistance and anti-wear performance of lubricating greases.
Most commonly used greases—such as calcium-based, sodium-based, and barium-based single-metal soap greases—tend to soften, bleed, or volatilize under high temperatures, losing their lubrication effectiveness. This often leads to equipment wear, increased noise, or even damage, adversely affecting normal production operations.
To address these challenges, EUBO has introduced its high-temperature grease, designed to provide reliable lubrication under extreme operating conditions.

Dry film lubricants are coating materials in which solid lubricant particles are dispersed within a binder system. After application, they can cure at room temperature or under heat, forming a solid lubricating film with specific functional properties. These products combine the advantages of lubrication technology and surface engineering, making them an essential part of modern high-performance lubrication materials, and they are widely used across various industrial sectors.
To ensure that dry film lubricants deliver optimal performance, proper surface preparation and application procedures are crucial. The specific steps are as follows:
Before coating, it is essential to thoroughly remove oils, dust, and oxides from the substrate surface. Inadequate cleaning will directly affect the adhesion strength and service life of the coating.
The substrate should undergo chemical conversion (e.g., phosphating, passivation) or physical treatment (e.g., sandblasting, roughening) to significantly enhance the bonding between the film and substrate. This step is indispensable in the application process.
After surface pretreatment, any residues must be removed, and the substrate must be completely dry to prevent moisture or contaminants from compromising the coating quality.
Depending on the operating conditions and functional requirements of the components, an appropriate application method—brushing, spraying, or dipping—should be selected. The coating is then cured under the recommended conditions, forming a uniform and stable dry lubricating film.
Dry film lubricants are suitable for a wide range of materials, including metals, plastics, and rubber, and perform exceptionally well in situations where conventional lubricants are insufficient. They can be used in combination with conventional lubricants for synergistic effects or applied alone as a permanent or corrosion-resistant lubrication solution.
Their applications span office equipment, household appliances, automotive manufacturing, and general machinery, and extend to high-tech sectors such as aerospace. They are suitable for trial assembly, friction control, corrosion protection, and long-term lubrication requirements.
High-temperature environment: Under high-speed and heavy-load operating conditions, gear components often experience elevated temperatures, with local temperatures reaching 200–300°C. If the grease lacks sufficient high-temperature resistance, its base oil and thickener are prone to thermal oxidation, resulting in a decline in lubrication performance.
Influence of chemical contaminants: Prolonged exposure of grease to air, or contact with industrial gases containing sulfur, nitrogen oxides, and other contaminants, can accelerate the oxidation process, leading to structural degradation and an increase in acid value.
Choose grease products with excellent antioxidant properties and thermal stability, especially under high-temperature and heavy-load conditions. Pay attention to their oxidation induction period and corrosion resistance.
Maintain proper sealing of the gear system to prevent ingress of water, dust, and other contaminants. Regularly clean the equipment and inspect the condition of lubricated parts.
By improving heat dissipation conditions or adding cooling devices, the gear system temperature can be maintained within a reasonable range, helping to extend the service life of the grease.
Develop a grease replacement cycle based on equipment usage, and monitor the grease oxidation status through oil analysis techniques to implement preventive maintenance.
Proper grease selection is key to ensuring the long-term stable operation of gears. It is recommended not to choose ordinary grease based solely on price, but to focus on technical compatibility and product reliability. Prioritize suppliers with comprehensive R&D capabilities and proper certifications to ensure optimal lubrication performance and equipment longevity.

The smooth and controlled opening and closing of a toilet seat is attributed to the sophisticated design between the damping shaft and the shaft sleeve. When the seat is lifted, motion is transmitted through the bearing, allowing the shaft and sleeve to rotate together. During this phase, the damping mechanism remains inactive, ensuring the cover can be raised effortlessly.
When the seat begins to descend, the intricate directional locking mechanism engages, causing the shaft and sleeve to disengage and the shaft to form a reverse lock with the sleeve base. Through the combined action of the damping mechanism and the damping grease, the toilet seat closes slowly and uniformly, achieving a smooth and steady descent.
Damping Grease
Damping grease is a specialty lubricant formulated from high-viscosity synthetic oil, specifically designed for mechanisms requiring cushioning, such as toilet seat hinges. It operates reliably over a wide temperature range of -30°C to 150°C and is safe, non-toxic, non-corrosive, and low in volatility.
More importantly, it provides excellent anti-wear lubrication and outstanding damping performance, effectively slowing the descent of the toilet seat during closure. This prevents harsh collisions between the seat and the toilet bowl, eliminates noise, reduces potential damage, and enhances the overall user experience. It also finds broader applications in other mechanisms requiring controlled cushioning.
In addition to its use in toilet seat slow-close systems, damping grease is also widely applicable to various mechanisms requiring cushioning and noise reduction, such as door and window hinges, furniture hinges, and rotating shafts. Whether applied to metal or plastic hinges, it provides long-lasting protection and ensures smooth operation, significantly enhancing the durability of the product and the overall user experience.
Damping grease is a functional grease made from specially selected polymers, specialty additives, and thickeners through a unique manufacturing process. It features excellent adhesion, high viscosity, superior lubrication performance, chemical stability, and mechanical stability. It is particularly suitable for positions between plastics and metals that require long-term damping (buffering, resistance) and lubrication.
Typical application areas of damping grease include:
Sealing and leak-prevention parts: Such as sealing valves in water or fuel gates, used for lubrication and leak-proof filling.
Precision instruments: Parts that require damping and buffering.
Household products: Items that need cushioning or a naturally comfortable tactile feel.
Hardware and power tools: High-end door hinges, faucets, power tools, and movable joints in plastic toys.
Office equipment and mechanical structures: Internal plastic or metal moving parts in office equipment, toys, gearboxes, etc., requiring lubrication, noise reduction, shock absorption, or resistance functions.
