polymer_dielectric_constant_30

polymer

This is a high-permittivity polymer dielectric material engineered to achieve a dielectric constant around 30, significantly higher than conventional unfilled polymers. Such materials are typically synthesized by incorporating high-k ceramic fillers (like barium titanate or similar oxides) into a polymer matrix, or through specialized polymer chemistry. High-permittivity polymers are used in capacitive energy storage, printed circuit board interlayers, and miniaturized electronic components where space constraints demand greater capacitance density without increasing physical dimensions.

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.
