polymer_dielectric_constant_81

polymer

This is a high-permittivity polymer dielectric material, likely a filled or engineered polymer composite designed to achieve a dielectric constant around 81—significantly higher than unfilled polymers. Materials in this category typically combine a polymer matrix with ceramic or conductive fillers (such as barium titanate, alumina, or carbon-based additives) to enhance electrical storage capacity while maintaining some of the processing advantages of polymers. High-permittivity polymers are used in energy storage, miniaturized capacitors, and sensing applications where compact size and moderate frequency operation are priorities; they offer a middle ground between traditional polymers (lower permittivity, easier processing) and ceramic dielectrics (higher permittivity, brittleness, higher cost).

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.
