ALCUDIA CP-121 Repsol YPF Polyethylene, Low Density

Product Description

Alcudiai® CP-121 is high molecular weight LDPE compound that has been widely used as insulation for telephone and coaxial cables. This product has been specially designed to provide a superior performance at high-speed extrusion together with a smooth surface finish of the cable.
ALCUDIA® CP-121 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.
