polymer_dielectric_constant_82

This is a high-dielectric-constant polymer material, likely an engineered thermoplastic or thermoset resin formulated to achieve elevated relative permittivity (dielectric constant ≈ 8.2) compared to conventional unfilled polymers. High-k polymers are developed for electrical and electronic applications where capacitive storage, signal coupling, or dielectric isolation at reduced thickness is advantageous—offering a balance between the processability of polymers and performance characteristics traditionally reserved for ceramics or composites.
