Density of Common Dielectric Materials
Dielectric materials are non-conductive insulators that are widely used for electrical insulation and in capacitors. The density of dielectric materials can vary depending on the specific material, but they generally have relatively low to moderate densities compared to conductive materials.
The following table provides a list of density values for common dielectric materials at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
