Overview
Rokolub® P-B-220 is a synthetic base oil formulated as a water-insoluble, single-end-capped-type polyalkylene glycol (PAG) and ISO 220 viscosity grade. It is designed for demanding industrial lubricant applications requiring high load-carrying performance and long-term stability. It belongs to the API Group V base oils, which are characterized by their unique properties, such as exceptional oxidation stability and high-temperature performance. Their high thermal and oxidative stability enables extended service life and reliable operation under high temperatures. Rokolub® P-B-220 is also compatible with a wide range of metals, elastomers, and additives, making it an ideal base oil or lubricity additive for various fluids, including machining fluid, hydraulic fluid, and compressor lubricants. Rokolub® P-B-220 is acceptable for use in lubricants with incidental food contact (HX-1) for use in and around food processing areas.

Problems Solved
Heavy-duty lubricants that lack sufficient lubrication and stability from their base oils can cause serious operational failures. Lack of effective lubrication and wear protection leads to premature component wear and unexpected downtime. Without proper thermal and oxidative stability, fluids will deteriorate under extreme-temperature conditions, leading to degradation, deposits, and additional wear.
Applications
Gas compressor lubricants
Air conditioning compressor lubricants
Hydraulic fluid
Synthetic lubricants
Machining fluid
