With excellent thermal conductivity, electrical properties and high flash/ fire points, synthetic esters provide long-lasting, high-performance cooling for modern transformers and increasingly sophisticated EV batteries. A combination of low viscosity and volatility, high thermal stability, and materials compatibility make synthetic esters a preferred base stock choice.
