polymer_dielectric_constant_245
polymerThis is a polymer-based dielectric material engineered to achieve a dielectric constant of approximately 2.45, positioning it in the low-to-moderate permittivity range suitable for electrical insulation and signal transmission applications. Polymeric dielectrics with this property level are widely used in high-frequency electronics, printed circuit boards, and cable insulation where controlled permittivity minimizes signal distortion and dielectric losses. The relatively modest dielectric constant compared to ceramic alternatives makes this material particularly valuable in applications requiring both electrical performance and mechanical flexibility, lightweight design, or cost efficiency.

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.
