polymer

This is a high-dielectric-constant polymer material, likely a composite or engineered polymer formulation designed to achieve elevated relative permittivity compared to conventional commodity polymers. High-dielectric polymers are typically used in electrical and electronic applications where compact capacitive or insulating components are required without resorting to ceramic or solid-state 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.
