Polyurea Grease
High-performance polyurea-based grease with a metal-free soap structure, delivering extended service life and quiet operation.
Product Overview
ARNOCO Polyurea Grease is formulated with high-quality synthetic base oil thickened by organic polyurea compounds. Unlike traditional metal soap-based greases, polyurea thickeners contain no metal ions and do not catalyze base oil oxidation, delivering exceptional oxidative stability and an extended service life.
Ideal for motor bearings, precision instrument bearings, food machinery, high-temperature chains, and other applications requiring long grease life and high cleanliness. With its low-noise characteristics and superior oxidation resistance, polyurea grease is the ideal choice for lubricating high-end equipment.
Core Advantages
Ultra-long service life
Polyurea soap structure contains no metal ions, does not catalyze base oil oxidation, and offers a service life 3 to 5 times longer than conventional lubricating greases.
Low-noise operation
Uniform fiber structure and excellent adhesion reduce bearing noise, making it ideal for noise-sensitive applications.
Superior antioxidant performance
Polyurea inherently offers antioxidant properties, resists hardening and coking at high temperatures, and maintains long-term lubrication performance.
