polymer

This is a high-dielectric-constant polymer material, likely a specialty engineering plastic or composite designed to store electrical charge efficiently. Such polymers are used in electrical and electronic applications where compact capacitive performance is required without sacrificing the lightweight and processability advantages of polymer matrices. The notably high dielectric constant makes this material valuable for miniaturized electronics, high-density energy storage, and specialized insulation applications where traditional polymers or ceramics may be impractical.

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.
