polymer

This is a polymer-based dielectric material, likely formulated to achieve a relatively high dielectric constant around 2.14, which suggests it may be a filled or engineered polymer composite rather than an unfilled polymer resin. The elevated dielectric constant makes it suitable for applications requiring enhanced electrical permittivity while maintaining polymer processing advantages and lower density compared to ceramic alternatives. Such materials are commonly used in capacitors, insulation systems, and high-frequency electronic components where controlled dielectric response is critical; they offer a balance between electrical performance, mechanical workability, and cost-effectiveness compared to pure ceramic dielectrics.

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.
