polymer

This is a high-permittivity polymer dielectric material, likely a thermoplastic or thermoset resin formulation engineered to achieve a dielectric constant around 20—significantly higher than standard polymers (typically 2–4) through incorporation of high-κ fillers or polar polymer matrices. Such materials are used in electrical and electronic applications where compact capacitive performance or energy storage is required without resorting to ceramics or traditional inorganic dielectrics. The elevated dielectric constant enables engineers to design smaller, lighter capacitors and energy storage devices while maintaining the processing ease, impact resistance, and cost advantages of polymers over rigid 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.
