polymer_dielectric_constant_94

polymer

This is a polymer-based dielectric material identified by its dielectric constant value of 94, indicating a high-permittivity polymer composite or filled polymer system. Such materials typically contain ceramic fillers (like alumina, titania, or barium titanate) dispersed in a polymer matrix to achieve elevated permittivity while maintaining processability. High-permittivity polymers are used in applications requiring compact capacitive components, energy storage devices, and electrical insulation systems where miniaturization and design flexibility are advantages over traditional ceramic dielectrics.

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.
