polymer_dielectric_constant_17

polymer

This is a high-permittivity polymer dielectric material, likely a filled or engineered polymer composite designed to achieve a dielectric constant around 17—significantly higher than unfilled base polymers. Such materials are typically produced by incorporating high-k ceramic fillers (such as barium titanate, alumina, or similar) into a polymer matrix, or through specialized polymer chemistry. High-permittivity polymers are used in capacitive energy storage, high-density interconnect applications, and miniaturized electronic packaging where conventional dielectrics cannot meet volumetric or performance constraints. The elevated dielectric constant makes this material valuable in environments where reducing physical size while maintaining electrical performance is critical.

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.
