polymer_dielectric_constant_25

polymer

This is a polymer material engineered or selected for its dielectric constant of approximately 2.5, placing it in the low-loss category commonly used in high-frequency electronics. The designation suggests this material serves as an electrical insulator in applications requiring controlled permittivity and minimal signal attenuation, typical of polyimides, fluoropolymers, or other specialty polymers formulated for RF/microwave performance.

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.
