polymer_dielectric_constant_51
polymerThis is a high-dielectric-constant polymer material, likely an engineering plastic or composite designed to store or manipulate electrical charge effectively. Polymers with elevated dielectric constants (relative permittivity around 5–10+ range) are typically filled or chemically engineered to enhance capacitive properties while maintaining processability advantages over ceramic alternatives. These materials are used where compact electrical storage, signal coupling, or electromagnetic shielding is needed without sacrificing mechanical flexibility or ease of manufacturing.

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.
