Abstract

This study explores the impact of adding conventional mineral oil (10%, 30%, and 50%) to new natural esters (Jatropha-based methyl ester and refined coconut oil). Examining dielectric, fire properties, and gassing tendencies, samples undergo accelerated aging at 130 °C with metallic substances. Results reveal that up to 30% mineral oil enhances or maintains the electrical and physical properties of natural esters, with dissipation factor reduction and viscosity improvement (by a factor of 2 at 50% mineral oil). Overall, mineral oil positively influences the insulating properties of natural esters under the described test conditions, suggesting potential applications in electrical systems.
