polymer_dielectric_constant_305

polymer

This is a polymer-based dielectric material identified by its relative permittivity of approximately 3.05, placing it in the low-to-moderate dielectric constant range typical of many commodity and engineering polymers. Materials in this category are commonly used in electrical insulation, printed circuit board substrates, and microwave/RF components where controlled dielectric 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.
