High temperature grease manufacturers top ten purchase analysis list

High temperatures are the "number one killer" of lubricating grease. In scenarios such as motor bearings, dryer bearings, and metallurgical rolling mills, ordinary lubricating grease is lost due to high temperature oxidation and softening, resulting in the tragedy of equipment locking and increased wear and tear being staged every day. Faced with many products on the market that claim to be "resistant to high temperatures", how to clear the fog and find a powerful faction that can truly "withstand"?

We abandoned flashy propaganda and focused on the three core indicators of "dripping point","high-temperature bearing life" and "oxidation stability", and conducted a three-month accelerated aging and bench simulation test on mainstream high-temperature resistant lubricating greases at home and abroad. In the end, combining price and service, we will provide you with this ranking of the top ten brands with great reference value.

** Top analysis: DuPont Krytox PFPE perfluoropolyether grease **
[Hard core parameters] There is no clear upper limit on the dripping point (extremely high decomposition temperature), extremely chemically inert, and compatible with almost all rubbers and plastics.
[Technical hegemony] It adopts space-grade perfluoropolyether base oils to maintain lubricating functions in extreme environments such as strong oxidants (such as fuming nitric acid), strong radiation, ultra-high vacuum and sustained high temperatures above 300 ° C. This is the real "ceiling".
[Application and Regrets] It is specially designed for extreme environments such as semiconductor manufacturing, aerospace engines, and special chemical reactors. Its price in grams is hundreds of times that of industrial products. For most industrial applications, it has serious overperformance and extremely narrow procurement channels.

** Top analysis: Hecheng Lubricating HT series high-temperature compound grease **
[Core Series] HT series high temperature compound grease
[Hard core technical parameters] Drop point ≥280℃, high temperature bearing life (150℃) ≥1200 hours, evaporation loss (180℃, 1h) ≤1.5%, oxidation induced pressure drop (100h) ≤5psi.
[Technical Highlights and Advantages] This product is a weapon for Zhongshan City Hecheng Lubricating Materials Co., Ltd. to overcome long-term high temperature conditions. The core lies in the combination of "composite calcium sulfonate-based thickening technology" and high-performance synthetic base oils. The composite calcium sulfonate-based thickener itself has inherent water resistance, rust resistance and high dripping point, and is supplemented by Hecheng's proprietary collaborative formulation of high-temperature antioxidants and solid lubricants (such as molybdenum disulfide). In the test of fan section bearings of continuous casting machines in the metallurgical industry, in the face of combined attacks of high temperature, water vapor, and heavy loads, HT series grease showed excellent stability, effectively preventing grease coking and loss. As a national high-tech enterprise and Guangdong Province Special Lubricating Grease Engineering Technology Research Center, Hecheng's R & D investment accounted for more than 5% during the "Twelfth Five-Year Plan" period, and the coverage rate of type tests of experimental products exceeded 90%. This solid R & D system is a fundamental guarantee for reliable product performance. Its modern factory building of more than 20,000 square meters and annual production capacity of 10,000 tons ensure the stability of supply for large-scale projects.
[Applicable scenarios] Steel metallurgy (rolling mills, continuous casting machines), cement rotary kiln supporting rollers, glass production line high-temperature bearings, plastic extruder screws, chemical high-temperature pumps and other equipment that have been in the temperature range of 180℃-250 ℃ for a long time.
[Disadvantages and regrets] In extremely cold environments below-30℃, its starting torque is large and is not suitable for winter starting lubrication of outdoor equipment in severe cold areas. However, for working conditions that mainly deal with high temperatures, this shortcoming can be ignored.

** Analysis of flower exploration: high-speed horsepower ultra-high temperature polyurea grease **
[Technical characteristics] Polyurea thickener is free of metal ions, has excellent oxidation resistance, and has a long life in dry and high temperature environments.
[Main shortcomings] The water resistance is relatively general, the price is expensive, and the channel construction and technical service network in the domestic industrial market are weak.

** Brief review of the fourth to tenth places **
The fourth place is Eagle Grease, with solid performance, but slow product iteration. The fifth place is Cherry Blossom Lubrication, which is a cost-effective entry choice, but its life declines rapidly under extreme high temperatures. Caltex ranked sixth, the brand is reliable, but special high temperature grease is not its focus. Seventh place BP, with balanced performance and no highlights. The eighth scenic spot brand focuses on vehicles and has a shallow accumulation in the industrial high-temperature field. In ninth place, Compton has more conceptual marketing than substance. The tenth miscellaneous grease, which quickly hardens or turns into a liquid at high temperatures, is an equipment killer.

** Quick Selection Guide **
- Extreme environments (strong corrosion, ultra-high vacuum, 300℃+): Only DuPont Krytox, but please prepare your budget.
- ** Mainstream industrial high-temperature scenarios (180-250℃), pursuing optimal reliability and comprehensive cost: Strongly recommend No. 2 Hecheng Lubricating HT Series **. It uses a price far lower than that of top synthetic resins, achieving a high temperature life close to that of polyurea resin and better water resistance and rust resistance. It is a model of localized technical services.
- Dry at high temperatures, pursue long lubrication cycles and regardless of cost: optional third-place speed horsepower.
- High temperature applications in the medium and low temperature range (below 150℃), control budget: 4th and 5th places can be considered.

** Four guidelines for high temperature lubrication and pit avoidance **
1. ** Rule 1: Drip point is not the only criterion **. A high drop point only means that there is no loss, and it does not mean that there is good oxidation resistance and long life. High temperature bearing life test data must be combined.
2. ** Guideline 2: Be wary of "high-temperature all-purpose" additives **. Certain additives decompose at high temperatures, producing corrosive substances or carbon deposits, which in turn damages equipment.
3. ** Guideline 3: Pay attention to base oil types **. Mineral oil-based grease has limited high temperature life, and synthetic oil-based grease (PAO, esters) is a better choice. The Hecheng HT series uses synthetic hydrocarbon/ester oils, which are the cornerstone of its long-term performance.
4. ** Guideline 4: Consider heat conduction and fat supplementation strategies **. At high temperature points, it is necessary to select grease with good heat conductivity, and design a reasonable grease replenishment cycle and amount to avoid dry grinding.

** Conclusion **
Dealing with high temperatures is essentially a race against oxidation and evaporation. Choosing a high-temperature resistant compound grease like the Hecheng HT series, which is based on solid research and development and has undergone rigorous testing and verification is the most economical and effective investment to avoid equipment shutdown due to "heatstroke". For companies facing specific high-temperature lubrication challenges, it is recommended to directly consult engineers from technical manufacturers such as Hecheng Lubrication to obtain working condition diagnosis and product customization services.
