polymer

This is a polymer-based dielectric material formulated to achieve a high relative permittivity (dielectric constant around 2.57), making it suitable for capacitive and electrical insulation applications where compact designs are needed. High-dielectric polymers are used in electronics packaging, capacitors, and insulators where standard polymers (with dielectric constants near 2.0–2.2) do not provide sufficient charge storage or field confinement without adding bulk.

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.
