polymer_dielectric_constant_84

polymer

This is a high-dielectric-constant polymer material, likely an engineered thermoplastic or thermoset formulation designed to achieve elevated relative permittivity (εr ≈ 8.4) compared to conventional polymers. The elevated dielectric constant makes it suitable for capacitive and electrical insulation applications where space-constrained designs require improved energy storage density or compact component geometries without sacrificing dielectric 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.
