polymer_dielectric_constant_56

This is a high-permittivity polymer dielectric material, likely an engineered thermoplastic or thermoset formulation designed to achieve a dielectric constant around 5–6, significantly higher than commodity polymers. Such materials are typically achieved through particulate filler incorporation (ceramic or ferroelectric fillers) or specialized polymer backbone chemistry, and are used in applications demanding compact capacitive devices, high-density energy storage, or electrical insulation in demanding environments where traditional polymers fall short.
