polymer_dielectric_constant_19

polymer

This is a high-permittivity polymer dielectric material, engineered to achieve a dielectric constant around 19—significantly higher than standard commodity polymers. Materials in this class are typically specialized formulations incorporating high-k fillers (ceramic particles, polymeric additives, or nanocomposites) to concentrate electrical charge storage without sacrificing processability. Applications span energy storage devices, high-capacitance passive components, and power electronics where compact form factors and electrical performance are critical; such polymers offer a practical middle ground between conventional plastics and inorganic ceramics, enabling integration into flexible or moldable structures where rigidity is undesirable.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
