polymer_dielectric_constant_137

polymer

This is a high-permittivity polymer dielectric material, likely an engineering polymer or polymer composite formulated to achieve elevated dielectric constant values suitable for electrical and electronic applications. The high dielectric constant makes it valuable for capacitive applications, energy storage devices, and electrical insulation systems where compact designs and enhanced charge storage are required compared to conventional polymers.

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.
