polymer

This is a polymer-based dielectric material engineered to have a relative permittivity of approximately 7, positioning it in the mid-range of polymer dielectrics between standard plastics (ε~2–3) and high-k ceramics (ε>10). It is used in electronic components where moderate dielectric strength, reasonable loss characteristics, and processability are balanced requirements, such as in capacitor films, printed circuit board substrates, and insulation layers where space constraints or thermal management demands a higher dielectric constant than conventional polymers. The material's appeal lies in combining the mechanical flexibility, ease of manufacturing, and cost-effectiveness of polymers with improved capacitive performance, making it suitable for miniaturized electronics and energy storage applications where ceramic alternatives may be too brittle or difficult to integrate.

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.
