polymer

This is a high-permittivity polymer dielectric material, likely a composite or filled polymer system engineered to achieve elevated dielectric constant values. Such materials are typically based on polymer matrices (polyimide, epoxy, or polycarbonate) reinforced with high-κ ceramic fillers or structured to exhibit enhanced polarization. High-permittivity polymers bridge the gap between conventional plastics and ceramics, offering the processability and mechanical flexibility of polymers with improved electrical energy storage and capacitive performance.

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.
