polymer_dielectric_constant_290

polymer

This is a polymer-based dielectric material, likely an engineering plastic or composite formulated to achieve specific electrical insulation properties suitable for electronic applications. The designation references a dielectric constant of approximately 2.9, making it a low-to-moderate permittivity polymer useful where electrical isolation and minimal signal interference are required. Such materials are typically selected for printed circuit boards, capacitor films, or insulation layers where controlled electromagnetic properties are critical to device 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.
