polymer_dielectric_constant_52
polymerThis is a high-permittivity polymer dielectric material engineered to achieve a dielectric constant around 5.2, significantly higher than standard polymers like polyethylene or polypropylene. It is used in applications requiring compact capacitive devices, electronic packaging, and insulation layers where space constraints demand efficient energy storage or signal integrity without switching to ceramic dielectrics. The elevated dielectric constant makes it valuable for miniaturized electronics, flexible circuits, and substrates where traditional low-k polymers would require thicker sections to achieve the same capacitance.

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.
