polymer_dielectric_constant_118

polymer

This is a polymer dielectric material, likely an engineering plastic or composite designed for electrical insulation applications where moderate-to-high dielectric performance is required. The designation suggests it has been formulated or selected for specific capacitive or insulating properties relevant to electronic and electrical systems. Typical applications include capacitors, printed circuit board substrates, cable insulation, and high-frequency electronic components where controlling electrical permittivity is critical to device 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.
