polymer

This is a high-permittivity polymer dielectric material engineered to achieve a dielectric constant around 120, significantly higher than conventional unfilled polymers. Such materials are typically achieved through polymer composites (often epoxy, polyimide, or polystyrene matrices filled with high-k ceramic particles like barium titanate or alumina) and are used in applications requiring compact capacitive or energy storage devices where traditional ceramics or inorganic dielectrics are impractical due to brittleness or processing constraints. The elevated permittivity enables thinner dielectric layers and reduced component volume, making it valuable for miniaturized electronics and high-density energy storage, though engineers must balance improved capacitance density against potential trade-offs in mechanical flexibility, thermal stability, and cost compared to neat polymers.

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.
