polymer

This is a polymer-based dielectric material, likely a thermoset or thermoplastic resin formulation designed for electrical insulation applications requiring moderate-to-high dielectric performance. Polymeric dielectrics are widely used in electronics, power distribution, and high-voltage applications where electrical insulation, breakdown resistance, and low dielectric loss are critical; compared to ceramic or mineral oil alternatives, polymers offer advantages in processability, weight reduction, and cost-effectiveness, though they typically require careful thermal and moisture management.

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.
