Polrex
Pal Polrex-2 Grease is a high-performance mineral-based Polyurea grease with Di-urea thickener, engineered for high-speed electric motor bearings. It offers superior water resistance, rust protection, thermal stability, and long-lasting lubrication—ideal for fill-for-life use.
Products Description
Mineral base Polyurea Grease, based on Di-urea thickener chemistry. It is specifically designed for high-speed electrical motor bearing. It has excellent resistance to water washing off, robust shear stability and rust prevention characteristic. It retains lubrication film for longer period of time than that of lithium complex. These greases are preferred for fill for life it is due to its superior thermal stability and its ability to regain the structural uniformity even after continuous shearing.
Product Features
- Improved Lubrication film strength.
- Excellent water washout and spray off resistance.
- Low Noise.
- Outstanding thermal and mechanical stability.
- Optimized oil bleed characteristic.
- Good pumpability.
Recommended for
Electric motor bearing, OD fan medium or high-speed bearing, Ball (roller) bearing operated under high temperature & Water Pumps.
Packing
180Kg, 18Kg.
