polymer

This is a polymer-based dielectric material, likely a thermoplastic or thermoset resin engineered for electrical insulation applications where controlled dielectric properties are critical. The specific composition is not disclosed in available data, but materials in this category are typically used in capacitors, printed circuit boards, and high-voltage electrical systems where they must balance electrical insulation performance with mechanical stability and thermal tolerance.

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.
