Material Notes:
Borcell LE1120 is a low density polyethylene intended for the insulation of coaxial and radio frequency communication cables.. It contains no additives and is designed to give the lowest possible attenuation by the selection of "electrically clean" feedstock. Strict cleanliness requirements are applied in production and materials handling. Borcell LE1120 is designed to be used as insulation for radio frequency cables having extra high demand on low attenuation at high frequencies. By blending weight a suitable stabilized HDPE component prior to the extrusion, in an optimum ratio for each insulation thickness, the lowest possible attenuation can be achieved. A small amount of HE1102 is recommended as nucleating agent. Using optimized-processing conditions an expansion above 80% can be expected.Information provided by the Manufacturer.
