Generally resistant to animal and vegetable fats, oils, greases, ozone, heat, and strong oxidizing chemicals. Chlorobutyl has lowest permeability of all the synthetic rubbers.
working stability of greases
Petroleum products--Lubricating greases and oils--Determination of evaporation loss
The tribological properties and the anti-wear of micron copper powder in greases are investigated by four-ball test.
"Some molybdenum compounds (in which it has various valences) are used as pigments and catalysts. Molybdenum disulfide is a solid lubricant, used alone or added to greases and oils. "
Determination of colloid-stability of lubricating greases
