polymer

This is a polymer-based dielectric material, likely a thermoplastic or thermoset formulation engineered for electrical insulation applications where moderate-to-high dielectric constant performance is required. The material is used in capacitors, insulators, and electronic packaging where dielectric properties must balance electrical performance with mechanical processability and cost-effectiveness compared to ceramic or glass 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.
