High-Density Polyethylene (HDPE) Insulation Compound

High-Density Polyethylene Insulation Compound

High-Density Polyethylene (HDPE) Insulation Compound is a cable insulation material based on polyethylene (PE) resin, modified with additives such as antioxidants and stabilizers. Its core function is to provide electrical insulation protection for wires and cables while delivering excellent mechanical and chemical properties. This insulation material is suitable for the insulation layer of communication cables, optical cables, submarine cables, local telephone cables, coaxial cables, control cables, and power cables.
