CALTEX GREASES
Grease is a semisolid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil. The characteristic feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease. This change in viscosity is called shear thinning.
There are six kinds of Caltex greases available in the market: Marfak Multipurpose Grease, Multifak EP Grease, Starplex High Temperature Grease, SRI Grease, Thermatex Thermal Grease, Molytex Shock Grease and Aries Shock Grease. Please refer to the chart below for comparisons. One type may have a few NLGI variations depending on your needs.
