polymer_dielectric_constant_166

polymer

This is a high-dielectric-constant polymer material, likely a filled or engineered polymer composite designed to achieve elevated relative permittivity for electrical applications. The designation suggests this material family is used where conventional unfilled polymers cannot provide sufficient dielectric performance, making it relevant for capacitive energy storage, electrical insulation, and high-frequency signal transmission in compact form factors.

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.
