Description

Castrol Molub-Alloy™ 1000 HT (previously called Molub-Alloy™ 1000) extreme temperature grease utilises synthetic base oils in conjunction with a blend of lubricating solids selected for high temperature service. The synthetic fluids in Molub-Alloy 1000 HT were selected for their controlled low volatility, minimum residue after evaporation and high VI for additional film strength at elevated temperatures. The combination of synthetic fluids and a unique thickening system offers physical stability in prolonged service at high temperatures. Molub-Alloy 1000 HT remains more pliable than conventional high temperature greases. As a result of the higher viscosity synthetic base fluids used in Molub-Alloy 1000 HT, the film strength at elevated temperature is superior to that of petroleum base oils. It is also formulated with a combination of rust and oxidation inhibitors for prolonged service life without relubrication.

Application
Molub-Alloy 1000 HT is designed for use in applications where elevated temperatures are encountered, heavy and shock loading occurs, and where bearing speeds are low to moderate. Molub-Alloy 1000 HT has been successfully used in a wide range of elevated temperatures industrial applications such as:
In overhead sealed trolley wheel conveyor bearings passing through paint drying ovens in an air conditioner manufacturing plant. Temperatures reached 180°C/356°F and relubrication cycles were every 8 months
In overhead sealed trolley wheel conveyor bearings passing through a paint drying oven in an automotive assembly plant. Temperatures reached 185°C/365°F with relubrication cycles every 6 months
In floor conveyor bearings passing through paint drying ovens in an automotive assembly plant. Temperatures of 190°C/374°F were reached with relubrication cycles every 6 months
In overhead sealed trolley wheel conveyor bearings passing through paint drying ovens of a motorcycle assembly plant. After 4 months without relubrication in temperatures of 180°C/356°F, the bead of product on the
outside of the trolley wheels was still soft and pliable. Relubrication cycles were every 6 months
In a cement rotary kiln as a gas-seal lubricant to minimise hot gas leakage

Advantages
Excellent friction reduction characteristics due to Molub-Alloy solid lubricants – easier start-up, reduced heat, and reduced energy leading to longer bearing life
Synthetic base fluid and unique thickening system – the combination of synthetic fluids and a unique thickening system offers physical stability in prolonged service at high temperatures. This combination makes Molub-Alloy
1000 HT more pliable than conventional high temperature greases, leading to longer bearing life, extended lubrication cycles and uninterrupted service
Molub-Alloy 1000 HT grease is engineered for prolonged service from 177°C/350°F to 288°C/550°F. Molub- Alloy
1000 HT also withstands intermittent exposure to temperatures up to 343°C/650°
Formulated to address environmental concerns – it is free of antimony, barium, lead, and zinc
