Comparison of High Temperature Dielectric Properties Between Epoxy Resins with Alicyclic and Bisphenol A

The purpose of this study is to elucidate the dielectric properties of alicyclic epoxy resins at elevated temperatures. Compared to common bisphenol A epoxy resins, alicyclic epoxy resins have a higher glass transition temperature and lower viscosity in the liquid state. Therefore, alicyclic epoxy resins are expected to exhibit good dielectric properties in high temperature environments. In this paper, we compare the dielectric properties of alicyclic epoxy resins and bisphenol A epoxy resins from room temperature to high temperature.
