polymer_dielectric_constant_143
polymerThis is a polymer dielectric material engineered for applications requiring moderate electrical insulation properties and controlled permittivity. The designation references a dielectric constant around 1.43, positioning it in the low-to-moderate permittivity range typical of commodity and engineering polymers. It is used in electrical and electronic applications where insulation performance and signal integrity must be balanced against cost and processability, competing with materials like polyethylene, polypropylene, and polyester resins.

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.
