polymer

This is a polymer-based dielectric material, likely a composite or engineered resin formulation designed to achieve a dielectric constant around 15.7—significantly higher than typical polymers. Such high-permittivity polymers are engineered through filler incorporation (ceramic particles, polymeric additives) or specialized polymer chemistry to meet demanding electrical insulation requirements. Applications span high-voltage electrical systems, capacitor technologies, and advanced electronics where space constraints require compact dielectric solutions with enhanced charge storage or voltage handling capabilities compared to conventional polymer insulators.

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.
