Polyurea Grease

Polyurea Grease is a non-soap thickened grease, where polyurea compounds form the thickener system instead of conventional metal soaps such as lithium or calcium. This unique chemistry provides inherent resistance to oxidation and thermal degradation, even at sustained high operating temperatures.

Unlike soap-based greases, polyurea greases do not rely heavily on oxidation inhibitors, making them highly stable over long service intervals. This characteristic makes polyurea grease an ideal choice for sealed-for-life bearings, electric motors, and continuous-duty machinery.

Key Properties of Polyurea Grease

Polyurea grease is designed to deliver consistent performance over extended periods in harsh operating conditions.

• Excellent thermal stability for continuous high-temperature operation
• Outstanding oxidation resistance, preventing grease hardening and sludge formation
• Superior mechanical stability under long operating cycles
• Low oil separation, ensuring consistent lubrication over time
• Good load-carrying and anti-wear protection
• Low evaporation loss at elevated temperatures
• Suitable for extended relubrication intervals and sealed applications
• Maintains smooth texture and lubrication film over long service life

These properties make polyurea grease one of the most reliable options for long-term industrial lubrication.

Applications of Polyurea Grease

Polyurea grease is widely used in industrial applications where heat, continuous operation, and reliability are the primary concerns.

Industrial Applications

• High-temperature rolling element bearings
• Electric motor bearings
• Continuous-duty conveyor systems
• Fans, blowers, and exhaust systems
• Steel mill machinery
• Industrial ovens, dryers, and furnaces
• Sealed bearing assemblies requiring long-life lubrication

Its stability and longevity make it particularly suitable for equipment operating around the clock.

Advantages of Polyurea Grease

Using polyurea grease offers significant operational and economic benefits for industrial users:

• Extremely long grease life, reducing relubrication frequency
• Reliable lubrication at sustained high operating temperatures
• Minimizes bearing wear and premature failure
• Reduces maintenance shutdowns and labor costs
• Enhances equipment reliability and uptime
• Ideal for modern machinery designed for long service intervals
• Lower total cost of ownership despite premium formulation

These advantages make polyurea grease a strategic choice for critical and high-value equipment.

Industries Served

Palco polyurea greases are widely used across industries that demand durability and long-term reliability, including:

• Steel and metal processing
• Power generation and utilities
• Manufacturing and continuous-process industries
• Electric motor and equipment manufacturing

Their performance makes them suitable for critical industrial lubrication programs.

Choosing the Right Polyurea Grease

Selecting the correct polyurea grease depends on operating temperature, duty cycle, load conditions, and relubrication frequency. Extreme long life greases are ideal for sealed or low-maintenance systems, while steel mill greases are recommended for high-temperature, heavy-load, and contaminated environments.

Palco’s technical team can support you in selecting the most suitable polyurea grease based on your specific application and operating conditions.

Extreme Long Life Grease

Extreme Long Life Grease is a polyurea-based formulation designed for applications where maximum service life and minimal maintenance intervention are required. It provides consistent lubrication over extended operating periods, even under high temperatures and continuous operation.
This grease is particularly suitable for:

• Sealed bearings
• Electric motors
• Fans and blowers
• Equipment where relubrication access is limited

Its excellent oxidation resistance ensures stable performance without grease hardening or breakdown.

Steel Mill Grease

Steel Mill Grease is a heavy-duty polyurea grease engineered to withstand the extreme conditions present in steel manufacturing environments, including high heat, heavy loads, shock, vibration, scale contamination, and water spray.
It provides:

• Stable lubrication at elevated temperatures
• Strong resistance to oxidation and thermal degradation
• Reliable protection under heavy load and shock conditions
• Extended bearing life in harsh steel mill operations

This grease is widely used in steel rolling mills, continuous casting lines, and other high-temperature steel processing equipment.
