polymer_dielectric_constant_221
polymerThis is a polymer material formulated for high dielectric constant performance, designed for electrical and electronic applications where capacitive storage or insulation properties are critical. The designation suggests this material achieves a dielectric constant around 2.21 (or higher depending on composition), making it suitable for capacitor films, insulation layers, and microelectronic components where standard polymers would require excessive thickness. Applications span consumer electronics, power conditioning, and signal transmission where compact, lightweight dielectric performance is valued over ceramic alternatives that are brittle and difficult to process into thin films.

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.
