Multipurpose Extreme Pressure Polyurea Grease NLGI GC-LB Certified

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.

Polytac EP is 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 for longer bearing life. It has excellent thermal and shear stability at high temperatures for long service life. It also has excellent low-temperature pumpability, is highly resistant to water washout, and protects against rust and corrosion.

Polytac EP is NLGI GC-LB certified for use as a multipurpose automotive wheel bearing and chassis lubricant.
