Description
CASTROL OPTILEB™ GR 9830 (previously named Molub-Alloy™ Foodproof 9830) is a special high-temperature grease
formulated from a synthetic oil and solid lubricants, developed for the lubrication of rolling and sliding bearings. This
blend provides for excellent wear protection, increased service life and extended relubrication intervals at the same time.
The grease is excellently suited for high-temperature applications in the food and beverage industries where minimum
lubricant consumption, drip-free lubrication and physiological safety are required. It can also be used as a safety sliding
agent for oxygen installations.
Application
Especially suited for applications in baking and drying ovens in the food and canning industries.
Due to its low volatility, is also suited for vacuum applications, e.g. coating installations.
May be used in continuous service up to 250°C and be exposed to temperatures up to 280°C for short-time
applications.
Advantages
Aging resistance at high temperatures
Thermal and chemical stability
Resistant to most solvents, even chlorinated hydrocarbons, strong acids, alkalis and oxidizing agents, e.g.:
acetone, benzene, benzol, boron trifluoride, bromine, chlorine, chlorobenzene, cyclohexane, dioxan, natural gas,
ethylene acetate, fluorine, halogens, potassium hydroxide, methylene chloride, methyl formiate, sodium
hydroxide, perchloro-ethylene, petroleum ether, hydrochloric and sulphuric acid, tetrahydrofurane, toluol, 1.1.1.
trichlorethane, trichlorethylene, xylol
Excellent lubricating properties – as measured by standard laboratory tests and extensive field evaluations
Extended relubrication intervals without undue risk of lubricant starvation or increased lubricant consumption
Below 280°C the lubricant resists the thickening and hardening which is typical of mineral oil products in hightemperature
applications
Minimum consumption, economic application and clean operating conditions
Compatible with the following sealing materials: NBR, EPDM, NR, MWQ, PVMQ, PA, PE, PUR, PTFE
Physiologically safe; approval by LGA (Bavaria)
