polymer

This is a high-dielectric-constant polymer material, likely a filled or chemically modified polymer designed to store electrical charge efficiently in compact form. Such polymers are used where electrical capacitance is needed in space-constrained applications, offering advantages over ceramics in terms of flexibility, processability, and impact resistance, though typically at lower dielectric constants than ceramic alternatives. The material represents an important class for modern electronics miniaturization and energy storage applications.

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.
