Product Overview
Formulated with a refined narrow-distillation mineral base oil, a detergent-dispersant and a high-temperature antioxidant for open or closed heat-transfer systems operating at up to 300 C.
Key Benefits
- Low volatility and high flash point support safe system operation
- Good fluidity and heat-transfer performance with low energy consumption
- Thermal-oxidation stability helps restrain acid-number and viscosity increase
- Good high-temperature thermal stability supports long-term operation
Applications
Petrochemical, synthetic-fiber, synthetic-resin, pharmaceutical, printing and dyeing industries.
