polymer

This is a high-dielectric-constant polymer material, likely a specialty engineering polymer or polymer composite designed to achieve elevated relative permittivity compared to standard polymers. Such materials are typically developed for capacitive energy storage, insulation systems, or high-frequency electronics applications where conventional polymers lack sufficient dielectric performance.

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.
