polymer

This is a polymer-based dielectric material, likely a thermoplastic or thermoset resin engineered to achieve a dielectric constant around 9.3—significantly higher than typical polymers (which cluster near 2–4). The elevated permittivity suggests incorporation of ceramic fillers, polar monomers, or specialized chemical structures designed to enhance electrical properties. This material bridges the gap between standard polymeric insulators and ceramic dielectrics, offering potential advantages in electrical density and miniaturization without the brittleness of ceramics. Applications focus on high-frequency electronics and capacitive systems where compact form factor and electrical performance are both critical; it competes with filled epoxies, polyimides, and polystyrene formulations where thermal stability or processing ease are secondary to dielectric 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.
