polymer

This is a polymer material engineered for high dielectric constant performance, likely a filled or chemically modified polymer system designed to store electrical charge efficiently. High-dielectric polymers are used in electrical and electronic applications where compact capacitive energy storage, signal coupling, or electromagnetic shielding is required, offering advantages over ceramics in terms of processability, mechanical flexibility, and cost in certain form factors.

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.
