polymer_dielectric_constant_196
polymerThis is a polymer material engineered or formulated to exhibit a dielectric constant around 1.96, positioning it in the low-to-moderate dielectric range typical of specialized polymer composites or fluoropolymer blends. Such materials are designed for applications requiring controlled electrical properties—neither as low as air-gap insulators nor as high as ceramic or high-κ polymers—making them useful in intermediate-permittivity circuit and electromagnetic applications.

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.
