polymer_dielectric_constant_90

polymer

This is a polymer-based dielectric material engineered to achieve a high relative permittivity (dielectric constant) around 90, making it useful for applications requiring significant capacitive energy storage or electrical field control in compact geometries. Polymers with elevated dielectric constants are employed in capacitors, energy storage devices, and high-frequency electronic components where traditional low-permittivity polymers would require impractically large volumes. The high dielectric constant distinguishes this material from standard polyethylene, polypropylene, and other commodity polymers, positioning it as a specialized choice for designers seeking to minimize component size without sacrificing electrical performance.

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.
