polymer_dielectric_constant_237
polymerThis is a synthetic polymer formulated to achieve a dielectric constant around 2.37, positioning it in the low-to-moderate permittivity range typical of engineering polymers. Such materials are engineered for electrical insulation and high-frequency applications where controlled dielectric response is critical to performance and signal integrity.

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.
