polymer_dielectric_constant_53

polymer

This is a polymer material formulated or selected for its relatively high dielectric constant (approximately 5.3), making it suitable for electrical insulation and capacitive applications where moderate permittivity is beneficial. Polymers with this dielectric range are used in capacitors, printed circuit boards, and other electronics where controlled electrical properties are needed without resorting to ceramic or inorganic alternatives.

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.
