polymer

This is a high-permittivity polymer dielectric material engineered to achieve a relative dielectric constant around 22, significantly higher than conventional unfilled polymers. Such materials are typically produced through the incorporation of high-k ceramic fillers (such as barium titanate, lead zirconate titanate, or alumina) into a polymer matrix, combining the processability of polymers with enhanced electrical performance. These composites are used where compact capacitive storage, high charge density, or improved electrical performance at lower thickness is required—notably in consumer electronics, power electronics, and emerging energy storage applications—offering advantages over purely ceramic alternatives in terms of mechanical flexibility, ease of fabrication, and cost-effective scalability.

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.
