Reasons For The Low Density Of Epoxy Resin Insulators

The structural density of epoxy resin high voltage epoxy resin is significantly lower than that of traditional ceramic or glass insulators. The key lies in its material composition: it uses epoxy resin as a matrix, often supplemented with glass fibers or fillers, and forms a composite structure through chemical curing. As a result, compared to insulators produced by sintering high-density ceramics, epoxy resin high voltage standoff contains more voids or lightweight components within its overall volume, thus reducing its overall weight.

During the polymerization process, the epoxy groups and ether bonds in the epoxy resin molecule structure ensure the volume stability of the cured polymer, but the overall skeletal density is not high. Compared to the dense mineral structure of ceramic materials, epoxy composites are closer to plastic/fiber composites, resulting in a lighter weight per unit volume.
