polymer_dielectric_constant_222
polymerThis is a synthetic polymer engineered to exhibit a dielectric constant around 2.2, placing it in the low-permittivity family of polymeric insulators. Such materials are typically employed in high-frequency electronics and RF applications where minimal signal loss and stable electrical properties across temperature and frequency ranges are critical; they are valued as alternatives to ceramics when weight reduction, ease of processing, or cost efficiency is prioritized over extreme performance demands.

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.
