Mobil Rarus™ PE R 220
Ethylene compressor oil
- ：
Product Description
Mobil Rarus™ PE R 220 is a premium ethylene compressor oil of ISO viscosity grade 220. It is a polymer thickened, food-grade white oil based lubricant used for the lubrication of ethylene hyper compressors.
In the production of polyethylene, high-speed reciprocating compressors are used to compress ethylene gas to high pressures up to 3000bar. In these applications, the compressor lubricant can come in contact with the polyethylene in the polymerization process. Under these circumstances, the lubricating oil required must be of acceptable purity and be known not to modify the properties of the polyethylene.
Mobil Rarus PE R 220 provides good lubrication of the compressor cylinders and is compatible with the polyethylene process. It can be used to produce polyethylene where food contact can occur such as in food packaging. Mobil Rarus PE R 220 offers good thermal and chemical stability.
Features and Benefits
Mobil Rarus PE R 220 is specifically engineered to help provide long and trouble-free compressor performance. Mobil Rarus PE R 220 is NSF H1 registered and meets the requirements of FDA regulation 21CFR 178.3570 for lubricants with potential for incidental food contact. Mobil Rarus PE R 220 also meets the requirements of FDA regulation 21 CFR 177.1520 for processing aids used in the production of olefin polymers intended for use in contact with food.
Mobil Rarus PE R 220 compressor oil offers the following benefits:
