polymer_dielectric_constant_104

This is a polymer-based dielectric material engineered to achieve a dielectric constant of approximately 10.4, placing it in the high-permittivity polymer class. Such materials are typically semicrystalline or filled polymer composites designed for electrical insulation and energy storage applications where standard polymers (dielectric constant ~3–4) are insufficient. High-permittivity polymers are used in capacitors, printed circuit board substrates, and flexible electronics where designers need greater charge storage density or improved signal integrity without the brittleness of ceramic dielectrics.
