Mobil Rarus™ PE KPL 201 is a medium viscosity, colourless oil, of viscosity slightly above ISO VG 100. It is based on high purity, saturated hydrocarbon oils, supplemented with friction-reducing and free-radical trap additives at adapted treat levels
Features and Benefits
- Low reactivity components. Do not interfere with polymerisation reactions.
- High purity components. Do not induce any discolouration or odour in the final polymer.
- Components approved for food contact. Suitable for the manufacture of polymers for food packaging containers.
- Reduced maintenance shutdowns
- Low polarity. Suitable in the manufacture of polymers for electrical insulation and thin sheets (plastic bags).
Mobil Rarus PE KPL 201 is specifically designed for the lubrication of very high pressure ethylene and co-monomers compressors. It may be used up to 3400 bars, according to oil injection system and temperature.
Mobil Rarus PE KPL 201 is formulated for the most demanding applications. Its viscosity and composition are tailored for the highest pressures found in ethylene compressors for LDPE production. The viscosity increase under the highest pressures remains low enough to ensure an adequate flow of lubricating oil.
Additives also prevent the early polymerisation of reactive gas components and impurities into the compressor itself, which may lead to formation of sludge, and eventually to lubrication failure. Additives also mitigate friction losses and bushing wear. As a result shutdowns for maintenance are less frequent.
