Features and Benefits

Mobilgrease XHP 681 is a leading member of the Mobilgrease brand of products, which has gained a reputation world-wide for innovation and performance excellence. Mobilgrease XHP greases are state-of-the-art products designed by our formulation technologists and backed by our world-wide technical support staff.

A key factor in the excellent adhesion and cohesion properties and high drop point of Mobilgrease XHP 681 is the proprietary manufacturing technology developed at our research facilities and adopted by our modern manufacturing facilities. These products use specially selected additives to provide excellent oxidation stability, rust and corrosion control, resistance to water contamination as well as anti-wear and EP protection. Mobilgrease XHP 681 offers the following features and potential benefits:

 

Features

Advantages and Potential Benefits

Superb resistance to water washout and spray-off

Helps assure proper lubrication and protection even in the most severe water exposure conditions

Highly adhesive and cohesive structure

Excellent grease tenacity helps reduce leakage and extend re-lubrication intervals for reduced maintenance requirements.

Excellent rust and corrosion resistance

Helps protect lubricated parts even in hostile aqueous environments, especially acidic water

Very good resistance to thermal, oxidative and structural degradation at high temperature

Extended grease life and enhanced bearing protection in high temperature applications helps reduce maintenance and replacement costs.

Very good anti-wear and EP performance

Provides reliable protection of lubricated equipment, even under conditions of high sliding and shock loading with potential for extended equipment life and reduced unanticipated downtime

 

Applications

Mobilgrease XHP 681 Mine is designed primarily for use in the mining industry where it is recommended by ExxonMobil for the lubrication of slow moving plain and rolling element bearings. It will provide extraordinary performance in contractor, construction, earthmoving, mobile and stationary equipment particularly where long lubrication intervals or oscillating/vibrating motion is present.
