A Quick Summary of the MBL Material Safety Data Sheet

The Lithium Complex soap structure with a micro metallic base lubricity matrix provides good high-temperature performance characteristics. In many conventional greases, load carrying additives normally limit high temperature performance but MBL Grease retains this feature whilst continuing to provide extreme pressure protection. MBL Grease provides dependable lubrication at low temperatures. Low temperature torque tests conducted at -40°C (-40°F) show MBL Grease to be suitable for use at temperatures at or above this level. The ability to retain a relatively soft consistency at low temperatures means that cold weather dispensing problems are minimised. MBL Grease has extreme pressure and anti wear characteristics that enable it to serve under conditions of high loading or severe shock loading.
