polymer_dielectric_constant_74
polymerThis is a polymer dielectric material engineered for high electrical insulation performance, characterized by a dielectric constant around 7.4. It is typically used in electrical and electronic applications where controlled dielectric properties are critical for circuit performance, signal integrity, or high-voltage isolation. Common applications include printed circuit board substrates, capacitors, and insulation layers in power electronics and telecommunications equipment, where this material offers a balance between electrical performance and processability compared to ceramic or glass-filled alternatives.

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.
