Specifications
Material: Black Bimodal High-Density Polyethylene (HDPE)
Melt Flow Index (MFI): 2 (g/10 min) at 190°C and 5 kg load, measured according to ISO 1133-1, Method A
Key Features
Physical Toughness: The compound provides superior mechanical strength that prevents it from suffering any kind of physical damage when it is handled, transported, or installed. This is an ideal solution for cables exposed to harsh conditions, including underground installations and environments where the mechanical stress is high.
Low Water Permeability: This jacketing compound is characterized by very low water permeability. Such a feature ensures that cables are protected from moisture ingress, which is very critical in the integrity and performance of energy and communication systems. Cables buried underground are very prone to water damage, and this jacketing compound provides a strong barrier against this risk.
Bimodal Structure: The bimodal polyethylene resin used in this compound refers to two different molecular weight distributions, which gives the material an ideal balance between flexibility and stiffness for both easy handling during installation and long-term durability once in place.
Applications: This jacketing compound is widely used in energy and communication cables, particularly where the cables are buried underground. The combination of strength and resistance to environmental factors like water, heat, and mechanical stress makes it the preferred material for these applications.
Energy Cables: This compound is widely used to cover power transmission cables in the energy sector, which need to withstand mechanical stresses and environmental challenges. Its strength will ensure that cables can withstand load without getting damaged during installation and its resistance to water will ensure the cables remain functional for the entire service life.
Communication Cables: For communication cables, especially those buried underground, protection from moisture is critical to maintain signal integrity. The low water permeability of this compound provides an effective barrier, ensuring that the cables function optimally over long periods
Advantages in Manufacturing
Processing Efficiency: The material's properties allow for efficient processing during cable manufacturing. It has a low melt flow index (MFI), which helps to control the flow of the material during extrusion, leading to uniform thickness and high-quality cable jackets
Cost-Effectiveness: Due to its high durability, cables made with this jacketing compound require less maintenance and offer a longer lifespan. This results in lower long-term costs for energy and communication companies
Installation Advantages
Easy Handling: Although the compound is tough, it retains enough flexibility to make the laying of cables easier. The handlers can bend and arrange cables with less effort, hence possibly causing less harm while laying
Durability: Once applied, the jacketing compound provides long-term protection against mechanical stress, environmental factors, and even chemical exposure in some cases. That is why it is a very reliable choice for energy and communication infrastructure that needs to last for decades.
The Black Bimodal High-Density Polyethylene (HDPE) jacketing compound is an ideal material for energy and communication cables, especially those buried underground. Its balance of strength, low water permeability, and processing efficiency make it a great choice for both manufacturers and end-users, with long-term performance and protection of cable systems.
