polymer_dielectric_constant_104
polymerThis is a polymer-based dielectric material engineered to achieve a dielectric constant of approximately 10.4, placing it in the high-permittivity polymer class. Such materials are typically semicrystalline or filled polymer composites designed for electrical insulation and energy storage applications where standard polymers (dielectric constant ~3–4) are insufficient. High-permittivity polymers are used in capacitors, printed circuit board substrates, and flexible electronics where designers need greater charge storage density or improved signal integrity without the brittleness of ceramic dielectrics.

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.
