polymer_dielectric_constant_129
polymerThis is a polymer-based dielectric material, likely a specialty engineering plastic or composite designed for electrical insulation applications where moderate dielectric constant (around 1.29× relative permittivity) is required. Polymers in this class are used where designers need reliable electrical isolation with good processability and cost-effectiveness compared to ceramics, and this material's moderate dielectric constant makes it suitable for applications requiring controlled capacitive behavior or reduced signal loss in high-frequency environments.

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.
