polymer_dielectric_constant_143

This 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.
