polymer_dielectric_constant_121

polymer

This is a polymer dielectric material engineered for electrical insulation applications where moderate-to-high dielectric constant is required. Polymers in this classification are used in capacitors, insulators, and high-frequency electronic components where the material must balance electrical properties with processability and cost-effectiveness compared to ceramic alternatives.

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.
