These unique synthetic base oils are used to formulate high performance lubricants and greases. They offer outstanding solubility and excellent hydrolytic and thermo-oxidative stability. The chart that follows offers a relative, property comparison of the KR products to other commonly used HX-1 base fluids.

Thermal Stability

The Cincinnati Milacron Thermal Stability Test is used to evaluate the thermal stability of fluids in the pres-ence of copper and steel at elevated temperatures for 168 hours. Normally, run at 135°C, KR-015FG and a PAO were tested at elevated temperatures (200°C and 225°C) both neat and with an package containing an antioxidant and a yellow metal deactivator. Not surprisingly, due to breakdown and polymerization, the PAO experienced a very high viscosity increase.

When tested using Pressure Differential Scanning Calorimetry versus both a white oil and PAO, at 200°C and 210° C, the KR products again demonstrated their superior oxidative stability.

NA-LUBE AO-142 is a butylated, octylated, diphenylamine antioxidant that can be used at levels up to 0.50% in food grade applications. It is ashless, non-corrosive and solu-ble in a wide range of H-1 base flu-ids. As shown in the test data that follows, additive levels of 0.2% and 0.5% NA-LUBE AO-142 in various base oils resulted in a significant increase in the lifetime as measured by RPVOT - ASTM D 2272. NA-LUBE AO-142 is a liquid product for easy incorporation and imparts enhanced thermal and oxidative stability.
