polymer

This is a polymer material engineered or formulated to achieve a dielectric constant in the range of approximately 3.0–3.08, making it suitable for electrical insulation and capacitive applications where moderate permittivity is required. The specific polymer class and composition are not detailed here, but polymers in this dielectric range are typically aromatic or specialty thermoplastics used in electronics, power distribution, and signal transmission where controlled electrical properties and low loss are critical.

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.
