polymer_dielectric_constant_27

This is a high-dielectric-constant polymer material, likely a filled or chemically modified polymer formulation designed to achieve a dielectric constant around 27—significantly higher than unfilled commodity polymers. Such materials are typically engineered through ceramic particle reinforcement (e.g., alumina, titania) or polar polymer blends to enhance electrical performance while retaining processability. High-κ polymers are valued in electronics and energy storage applications where compact capacitors, insulation layers, or charge-storage components require improved dielectric performance without resorting to rigid ceramics or specialized inorganic substrates.
