polymer_dielectric_constant_278
polymerThis is a polymer dielectric material characterized by a dielectric constant around 2.78, placing it in the low-to-moderate permittivity range typical of organic polymers. Such materials are commonly used in electrical insulation, capacitor films, and printed circuit board substrates where controlled dielectric behavior and minimal signal loss are required. The relatively modest dielectric constant makes this polymer suitable for high-frequency applications where maintaining low signal distortion and cross-talk is critical, distinguishing it from higher-permittivity ceramics or filled polymer composites.

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.
