polymer_dielectric_constant_194
polymerThis is a polymer dielectric material formulated to achieve a relative permittivity of approximately 1.94, positioning it in the mid-range of dielectric polymers for electrical and electronic applications. Materials in this class are engineered to balance electrical insulation properties with controlled dielectric response, making them suitable for capacitive and signal-transmission applications where moderate permittivity is advantageous. The specific composition details are not disclosed in this record, but polymers with dielectric constants around 1.9–2.0 are typically polyimides, polycarbonates, or specialty fluoropolymers that combine thermal stability with electrical performance.

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.
