polymer_dielectric_constant_192

polymer

This is a polymer-based dielectric material, likely a thermoplastic or thermoset resin formulated for electrical insulation applications where controlled dielectric constant is critical. Polymers in this category are engineered to balance electrical performance with mechanical properties, making them suitable for applications requiring precise permittivity control without the brittleness of 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.
