polymer

This is a high-dielectric-constant polymer material, likely a composite or filled polymer system engineered to achieve dielectric constant values around 11—substantially higher than unfilled commodity polymers. Such materials are typically produced by incorporating high-permittivity ceramic fillers (like barium titanate or alumina) into a polymer matrix, or through specialty polymer formulations designed for electrical applications. These polymers are selected when space constraints demand higher capacitance density, improved energy storage, or enhanced electrical performance compared to conventional polymers, making them valuable in compact electronics, power delivery systems, and advanced sensor applications where traditional ceramics or electrolytic capacitors are impractical.

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.
