When your high-speed bearings are also facing heavy loads and potential impact, Mammoth steps up to Polytac EP. This is a high-performance polyurea grease that doesn't just handle the heat—it handles the pressure. Because it uses a non-corrosive EP additive, it’s safe for "yellow metals" like bronze and brass, making it the superior choice for high-stakes industrial fans, pumps, and automotive wheel bearings where longevity is the goal.

Phillips 66® Polytac EP is a high-performance, multipurpose, extreme-pressure (EP) polyurea grease specially developed to provide long service life in automotive and industrial applications. It provides significant performance advantages over conventional soap-thickened greases in high-temperature, long-life, and sealed-for-life applications. Manufactured with high-quality base oils and a non-soap polyurea thickener, it is compounded with a non-sulfur-phosphorus EP additive that is non-corrosive to yellow metals and provides extra protection against wear under heavy loading. It features excellent thermal and shear stability, outstanding low-temperature pumpability, and high resistance to water washout. Polytac EP is NLGI GC-LB certified for use as a multipurpose automotive wheel bearing and chassis lubricant.
