polymer_dielectric_constant_141
polymerThis is a polymer dielectric material engineered for electrical insulation applications where moderate-to-high dielectric constant is required. The material is used in capacitors, printed circuit boards, high-frequency electronics, and other applications where controlled permittivity and electrical isolation are critical to device performance. Polymers in this dielectric constant range offer a balance between electrical properties and processability, making them preferred over ceramics in applications requiring flexibility, lower cost, or easier manufacturing.

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.
