Polyethylene
KHJAC-BH495 is a compound based on high-density polyethylene (HDPE) with evenly dispersed carbon black, specially designed for use in the outer sheath (jacket) of power and telecommunications cables. This compound provides excellent processability, high resistance to mechanical and thermal stresses, and stability against environmental factors such as UV light, moisture, and chemicals due to its engineered structure.
Role of Polyethylene Sheath in Cables
In the design of power and telecommunications cables, the outer sheath (jacket) is considered the first line of defense against environmental factors. The key functions of this layer are:
- Mechanical protection against impact, scratches, tension, pressure, and abrasion
- Chemical resistance against moisture, dirt, acids, alkalis, and oils
- Protection against UV and adverse weather conditions for outdoor applications
- Supplementary electrical insulation in specific cables
- Increase in cable lifespan for industrial and urban applications
High-density polyethylene (HDPE) is one of the most commonly used materials for this purpose as it combines rigidity, toughness, electrical insulation, relative flexibility, and high resistance. The addition of carbon black with proper dispersion significantly increases UV resistance, preventing polymer degradation over time.
