polymer_dielectric_constant_56
polymerThis is a high-permittivity polymer dielectric material, likely an engineered thermoplastic or thermoset formulation designed to achieve a dielectric constant around 5–6, significantly higher than commodity polymers. Such materials are typically achieved through particulate filler incorporation (ceramic or ferroelectric fillers) or specialized polymer backbone chemistry, and are used in applications demanding compact capacitive devices, high-density energy storage, or electrical insulation in demanding environments where traditional polymers fall short.

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.
