备注说明 | ALCUDIA® CP-121 is high molecular weight, low density polyethylene compound designed for telephone and coaxial cables. This product provides a superior performance at high-speed extrusion together with a smooth surface finish of the cable. This grade contains a special stabilization system for protection against thermal and shear degradation during processing and it also contains a metal deactivator to ensure long-term ageing properties.TYPICAL APPLICATIONSSolid insulation for telephone cables It is recommended a temperature profile between 150 - 220°C. Optimal processing conditions must be tuned for each production line, recommending to use filters and a break plate to increase the pressure in the cylinder and consequently improve the cable quality, homogenization and dispersion of pigments in the case of colored cableALCUDIA® CP-121 meets the following specifications: ISO 1872 PE KHN 23D003; ASTM D 1248 I, A5, Grade E5; NF C 32-060 ISM1; VDE 0207 Teil 2 24I1. |
