polymer_dielectric_constant_289
polymerThis is a polymer material with a relatively high dielectric constant, indicating strong electrical insulation properties and polarizability suitable for capacitive applications. The specific composition is not documented in this database, but polymers in this dielectric class are used primarily in electrical insulation, energy storage, and high-frequency circuit applications where controlling electric field response is critical. Engineers select high-dielectric polymers over standard plastics when they need improved capacitance density, better voltage performance, or enhanced electrical performance in compact form factors.

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.
