Rokolub® 50-B-120 is a water-soluble polyalkylene glycol (PAG) base oil with an ISO 100 viscosity grade, designed to impart excellent lubricity and anti-wear benefits to synthetic industrial lubricant formulations. Composed of ethoxylated and propoxylated butanol, the oil has an equal weight ratio of ethylene oxide and propylene oxide. The base oil's high viscosity index of 220 ensures it maintains viscosity over a wide temperature range, including conditions as low as −43°C. Rokolub® 50-B-120 is used in a wide range of industrial fluids, including metalworking, hydraulic, and compressor lubricants.

When industrial lubricants are not properly formulated with the appropriate base oils, equipment faces friction, wear, and heat-related failures. Poor anti-wear and lubrication properties lead to premature wear and damaged components, while poor thermal and oxidative stability result in oil degradation, sludge, and varnish.
