Castrol Pyroplex Gold provides extreme protection against wear for critical equipment. A semi-synthetic, extreme-pressure grease, Castrol Pyroplex Gold contains more than 20% solids and includes 6% molybdenum disulphide. Its formulation provides equipment with a protective barrier against wear, even during conditions of high load.
Castrol’s Pyroplex Gold grease exhibits extreme-pressure performance and mobility while maintaining its stayability. It is able to do this through Castrol’s trademarked Hydro-ActivationTM technology. When exposed to moisture, Pyroplex Gold’s hydro-activated additive creates an increase in tack and adhesion rather than softening and eventual wash-out.
In order to provide a measure of this, we took two of our NLGI 2 greases and measured mobility at 60F. This value was then divided by its water spray off results from the ASTM 4049 test (Mobility @ 60F [g/min] / Water Spray Off [ASTM D4049]). This result demonstrates Pyroplex Gold’s mobility and ability to stay in place.
