These are prepared by adding abrasion , oxidation , rust and foam preventive to high viscosity index base oils. High specific heat and thermal conductability. Can be used safely up to 300C in close systems , up to 200C in open system.
Benefits :
Has a high thermal stability and conductability
Can be easily pumped and resists to oxidation
Avoids corrosion , doesn’t foam
Low vaporazation , very good low temperature performance
