2. Dissolved in Water PAG Oil

Dissolved in water PAG oils, or water-soluble variants, offer unique miscibility properties that enhance cooling efficiency in water-mixed systems. They are widely used in water-glycol hydraulic fluids and metalworking applications, providing anti-wear protection and rust inhibition.

• Market Insight: Demand for water-soluble PAG is growing in industrial sectors focused on eco-friendly lubricants. For example, in metal forming processes, these oils reduce environmental impact while improving machinability. This segment is projected to achieve a higher CAGR as regulations push for water-based alternatives.

• Trend: European industries, driven by REACH compliance, are shifting toward these formulations for hydraulic systems in renewable energy equipment, such as wind turbines, where biodegradability is a key factor.
