polymer_dielectric_constant_288
polymerThis is a polymer material characterized by a dielectric constant of approximately 2.88, placing it in the moderate-permittivity polymer category. Polymers in this dielectric range are valued in electrical and electronic applications where controlled permittivity is required for signal integrity, capacitance tuning, or insulation without excessive polarization losses.

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.
