polymer

This is a polymer-based dielectric material, likely a specialty insulating polymer formulated or modified to achieve a dielectric constant around 2.16—a value between standard polymers and higher-permittivity ceramics. The specific composition is not disclosed, suggesting it may be a proprietary formulation, composite, or polymer blend designed for controlled electrical properties. Such materials are used in applications requiring moderate dielectric performance with the lightweight, processability, and cost advantages of polymers over 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.
