polymer

This is a polymer material engineered or formulated to achieve a dielectric constant of approximately 1.84, likely a thermoplastic or thermoset resin matrix (possibly epoxy, polyimide, or polystyrene-based) modified with fillers or additives to control electrical properties. Polymers with this dielectric constant range are widely used in electronics and RF applications where controlled permittivity is critical for impedance matching, signal integrity, and miniaturization. The material would be selected over alternatives when a balance of low dielectric loss, processability, and mechanical robustness is required—particularly in applications where competing materials (like ceramics or specialized laminates) would be too rigid or brittle.

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.
