polymer

This is a polymer-based dielectric material, likely a specialty engineering plastic or composite formulation designed for electrical insulation applications where controlled dielectric properties are required. The designation suggests a material with a dielectric constant around 1.63 (relative permittivity), which is typical of non-polar engineering polymers used in high-frequency electronics and power transmission systems. Such materials are chosen when lower dielectric loss and stable electrical performance across temperature and frequency ranges are critical—common alternatives include epoxy resins, polyimides, and fluoropolymers, each with different cost-performance trade-offs.

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.
