polymer

This is a high-dielectric-constant polymer material, likely a filled or engineered thermoplastic or thermoset designed to store and manage electrical charge effectively. High-κ polymers are used in capacitive applications where conventional materials cannot meet performance demands, offering advantages over ceramics in processability, impact resistance, and design flexibility while competing with specialized dielectrics in energy density applications.

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.
