polymer_dielectric_constant_70
polymerThis is a high-permittivity polymer dielectric material, likely a filled or engineered polymer composite designed to achieve a dielectric constant around 70—substantially higher than unfilled polymers. Such materials are typically produced by incorporating ceramic fillers (like barium titanate, ceramic powders, or similar high-k particles) into a polymer matrix to enable capacitive energy storage and electrical property tuning. High-permittivity polymers bridge the gap between conventional low-k plastics and rigid ceramic capacitors, making them valuable in compact electronics where flexible or conformable dielectric layers are needed while maintaining significant charge-storage capacity.

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.
