polymer_dielectric_constant_286
polymerThis is a polymer material characterized by a dielectric constant of approximately 2.86, placing it in the moderate-permittivity range typical of standard engineering polymers. It is commonly used in electrical insulation, circuit board substrates, and capacitive applications 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.
