| It is a high density polyethylene compound intended for the insulation of radio frequency coaxial cables. HE1123 is designed to give the lowest possible cable attenuation by the selection of electrical clean feedstock and contains limited amount of selected additives. HE1123 is designed to be used as insulation for radio frequency coaxial cables having an extra high demand on low attenuation at high frequencies. By blending with a suitable stabilised LDPE component, such as LE1120, in an optimised ratio, prior to the extrusion, the lowest possible attenuation and good foaming properties can be achieved. Please find more information on applications below. Applications HE1123 is designed to use as physically foamed insulation for: Radio frequency coaxial cables (50 Ohm) Specifications HE1123 meets the following material classification: ISO 1872-PE, KGHN, 62-D090 ASTM D 1248 Type IV, Class A, Category 3 The following cable material standards are met by HE1123: EN 50290-2-23 Cables manufactured with HE1123 using sound extrusion practice normally comply with the following cable product standards: IEC 61196 EN 50117 Special Features HE1123 consists of specially selected components to offer: Low attenuation at high frequency Expansion degree above 80%&& |
