polymer

This is a polymer-based dielectric material characterized by a dielectric constant of approximately 1.95, positioning it in the moderate-permittivity range suitable for electrical insulation and capacitive applications. The material is commonly encountered in high-frequency electronics, power distribution systems, and capacitor manufacturing where controlled dielectric properties are essential for managing electric fields and signal integrity. Engineers select this class of polymer dielectric for applications requiring a balance between electrical performance and mechanical workability, offering advantages over both lower-permittivity materials (which may not provide sufficient capacitance density) and higher-permittivity ceramics (which can be brittle and costly).

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.
