CASTROL PYROPLEX GOLD & HYDRO-ACTIVATION TECHNOLOGY

PRODUCT NEWS / Post date:
1 September 2014

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.

Castrol’s Pyroplex Gold will help you lower grease consumption and maintenance costs through resistance to water spray off. It excels in multiple bearing applications, sliding applications, bucket pins, highly shocked loaded areas, and asphalt paver auger bearings where extreme pressure and high heat exist.
