polymer_dielectric_constant_82
polymerThis 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.

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.
