Overview
Rokolub® 50-B-80 is a synthetic polyalkylene glycol (PAG) base oil reacted from equal parts ethylene oxide and propylene oxide, producing ethoxylated and propoxylated butanol with a terminal hydroxyl group. It is available as a colorless to yellow, homogeneous liquid with a high viscosity index of 220. With excellent solubility in water at 20°C, Rokolub® 50-B-80 is an ideal synthetic base oil for water-based compressor fluids, hydraulic fluids, textile lubricants, working fluids, and more. The polyalkylene glycol has superior lubricity, wear protection, and extreme-pressure performance. The base oil also delivers superior all-weather performance, providing high-temperature performance and maintaining stability in temperatures as low as −43°C.

Problems Solved
When machining fluids, hydraulic fluids, compressor oils, and other lubricants are not properly formulated with the right base oils, industrial systems face several challenges, including friction, wear, and heat-related failures. Poor anti-wear and lubrication properties lead to component damage and premature failure, while poor thermal and oxidative stability lead to oil degradation, sludge, and varnish.
