polymer_dielectric_constant_169

polymer

This is a polymer-based dielectric material, likely a thermoplastic or thermoset polymer engineered for electrical insulation applications where low dielectric loss and controlled permittivity are critical. The designation suggests this material has been formulated or selected for use in systems requiring specific dielectric constant performance, making it suitable for capacitive, high-frequency, or voltage-isolation applications where material selection directly impacts device efficiency and reliability.

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.
