Abstract

Liquid crystal thermoset epoxy resin is used as an electrical insulator on electrical conducting devices such as coils and transformers. The linear epoxy/mesogen/epoxy molecule of the liquid crystal thermoset epoxy resin results in a electrical insulator with a high degree of crystallinity. This results in an electrical insulator with mechanical and electrical properties suitable for use in high temperature, high stress environments.
