Mobilgrease XHP 222 receives NLGI HPM Grease certification

ExxonMobil’s Mobilgrease XHP™ 222 grease has been approved against the NLGI High-Performance Multiuse (HPM) Grease certification.

Mobilgrease XHP 222 is an extended service lithium complex grease intended for a wide variety of applications and severe operating conditions. This grease was designed to outperform conventional products by applying cutting-edge, proprietary, lithium complex manufacturing technology. Mobilgrease XHP 222 grease is formulated to provide excellent high-temperature performance with superb adhesion, structural stability and resistance to water contamination. It has a high level of chemical stability and offers excellent protection against rust and corrosion.

It is designed for a wide range of applications, including the industrial, automotive, construction and marine sectors. Its performance features make it an ideal choice for operating conditions including high temperature, water contamination, shock loading and extended relubrication operations.

The HPM Grease Certification Program of the National Lubricating Grease Institute (NLGI) ensures that all certified greases meet or exceed the High-Performance Multiuse grease specification requirements in the areas of mechanical stability, oil separation, water resistance, heat tolerance, corrosion resistance and load carry capacity. All licensed HPM brands undergo rigorous qualification testing using independent laboratories to ensure they meet the HPM performance requirements.

In July, Castrol’s Tribol GR SW 460-1 was the first grease to be certified against NLGI’s new High-Performance Multiuse (HPM) Grease certification. In addition, NLGI certifies its enhanced performance in corrosion protection, high load-carrying capacity and low temperature.

In addition to the HPM core certification, Mobilgrease XHP™ 222 has also received the +WR tag for enhanced level of performance in the water resistance category.

“We found the HPM approval process very easy and straightforward. One of the reasons we applied for the new NLGI HPM specification is the value of having an independent organization like NLGI review and approve the performance features of our high performance multiuse grease” said ExxonMobil’s Grease Technology Manager Gary Dudley.

In December 2020, NLGI launched its High-Performance Multiuse (HPM) Grease certification and sub-categories with enhanced performance in the following areas:

• HPM Core Spec
• HPM Grease Core with enhanced Water Resistance (HPM + WR)
• HPM Grease Core with enhanced Salt Water Corrosion Resistance (HPM + CR)
• HPM Grease Core with High Load Carrying Capacity (HPM + HL)
• HPM Grease Core with enhanced Low Temp Performance (HPM + LT)

Future specifications may include high temperature and/or long life. 

NLGI has partnered with the Center for Quality Assurance to administer the HPM program and conduct qualification testing. The initial focus of HPM is on premium grease in a variety of bearings and applications which require similar lubricating properties.
