polymer_dielectric_constant_164
polymerThis is a polymer-based dielectric material, likely an engineering plastic or composite resin formulated for electrical insulation applications. The designation references a high dielectric constant (~164), suggesting it may be a filled polymer composite or specialized engineering polymer designed to store or manage electrical charge in demanding environments. This material would be selected when standard polymers cannot meet the required dielectric performance, making it relevant for applications where electrical properties must be precisely controlled without sacrificing processability or cost relative to ceramic alternatives.

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.
