High Temperature Grease for Extreme Heat Applications
When standard lubricants carbonize and fail, our specialty formulations maintain structural stability. Engineered for continuous casting lines, high-speed electric motors, and furnace equipment operating at elevated temperatures.
- Thermal Stability: Continuous operation up to 250°C+ depending on thickener technology.
- Reduced Maintenance: Excellent oxidation resistance prevents grease hardening and carbon deposits.
- Supply Chain Flexibility: Custom formulations, private label packaging, and stable bulk supply available.

Why Standard Grease Fails at High Temperatures
Operating industrial equipment beyond 120°C exposes standard lithium greases to rapid degradation. Understanding these failure modes is critical for preventing unbudgeted downtime.
Catastrophic Bearing Failure due to Carbonization
Grease Hardening
Base oil evaporation leaves behind thickener residue, causing extreme friction and motor overload.
Oil Separation (Bleed)
Thermal stress breaks down the thickener matrix, causing the oil to leak out of the bearing housing.
Rapid Oxidation
Oxygen reactivity accelerates at high heat, turning grease into acidic sludge that pits metal surfaces.
Increased Maintenance Costs
Shortened relubrication intervals demand excessive labor and higher lubricant consumption.
What Is High Temperature Grease?
High temperature grease is a specialty lubricant engineered to maintain its protective film and structural integrity in environments where conventional mineral-oil-based greases oxidize, evaporate, or melt.
The Anatomy of Extreme Heat Lubrication
-
Base Oil (70-90%)
We utilize synthetic fluids (PAO, Esters, Silicone, or PFPE) that offer high flash points and low volatility compared to mineral oils.
-
Thickener System (10-20%)
The "sponge" holding the oil. We formulate with Lithium Complex, Polyurea, PTFE, or Inorganic clays (Bentonite) to resist melting up to 300°C.
-
Performance Additives (1-10%)
Antioxidants, anti-wear (AW), and extreme pressure (EP) agents specifically selected to remain stable at high temperatures.

How to Select the Correct High Temperature Grease
Step 1: Determine Operating Temperature
Identify continuous vs. peak intermittent temperatures. Above 200°C requires specialized synthetic base oils.
Step 2: Evaluate Speed and Load
High-speed bearings need lower base oil viscosity. Heavy loads require Extreme Pressure (EP) additives.
Step 3: Check Water Exposure
If washout is a risk, complex thickeners or specific polymers are necessary to maintain adhesion.
Step 4: Chemical Exposure
Presence of solvents, acids, or oxygen necessitates chemically inert formulations like PFPE.
Step 5: Material Compatibility
Ensure the grease does not swell or shrink plastic gears or elastomer seals (e.g., EPDM, NBR).
Step 6: Choose Technology
Match the findings to the appropriate thickener/oil combination.
