polymer_dielectric_constant_95

polymer

This is a polymer-based dielectric material engineered for electrical insulation applications where moderate permittivity (dielectric constant ~9.5) is required. It is used in capacitors, printed circuit board substrates, and electrical insulation layers where controlled dielectric response and dimensional stability are critical to circuit performance and reliability.

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.
