polymer_dielectric_constant_66

polymer

This is a polymer-based dielectric material characterized by a dielectric constant of approximately 6.6, placing it in the range of engineering polymers used for electrical insulation and capacitive applications. The material is suitable for high-frequency electronics, power distribution components, and applications requiring controlled dielectric response, where its moderate permittivity offers a balance between electrical performance and mechanical processability compared to 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.
