Crosslinked Polyethylene XLPE Material

XLPE material is the abbreviation of cross-linked polyethylene material. Cross-linked polyethylene (XL-PE) is an advanced material that has been chemically or physically modified. It is a polymer that enhances its performance by generating a cross-linked structure between polyethylene molecules. The molecular weight of XL-PE significantly affects its mechanical strength, thermal stability, and resistance to environmental stress cracking.

It is a commonly used raw material in the manufacture of wires and cables in the fields of new energy, photovoltaics, locomotives, etc. In cable applications, XL-PE-insulated cable is particularly favored for its excellent electrical insulation and resistance to harsh environments.

It has the characteristics of flame retardancy, UV resistance, mildew resistance, and high-temperature resistance. Its ability to withstand environmental stress cracking makes it highly durable for long-term applications.

At present, Angreen's XL-PE series products mainly include XL-PE, XL-PO, etc.

Angreen's XL-PE series wire and cable materials are environmentally friendly flame-retardant materials with added hydroxides and synergists.

The Main Features of XLPE Materials Include

Heat Resistance: XLPE's long-term operating temperature can reach 90°C, short-term fault temperature can reach 130°C, and short-circuit temperature can reach 250°C, which is suitable for high-temperature environments.

Electrical Properties: It has high dielectric strength and low dielectric loss, can effectively prevent current leakage, and ensure the safe and stable operation of electrical equipment. This makes it highly suitable for extra high voltage (EHV) cable insulation.

Chemical Stability: It has good resistance to acids, alkalis, and chemicals, and is suitable for harsh environments. Compared to high-density polyethylene (HDPE), XL-PE offers superior resistance to chemical corrosion and stress cracking.

Mechanical Properties: It has high tensile strength and impact resistance, allowing it to resist the influence of external forces.

Thermal Properties: Low thermal conductivity and thermal expansion coefficient help reduce heat loss and thermal stress.

Application Areas(Crosslinked Polyethylene XLPE for Cable Insulation and Cable Jacket)

XL-PE materials are widely used in the power industry and electrical equipment fields, especially in the following aspects:

Power Cables:  Used for the insulation layer of high-voltage cables due to their excellent heat resistance and electrical properties. XLPE-insulated cables are particularly useful for extra high voltage (EHV) transmission, ensuring efficient and stable power delivery.

Electrical Equipment: used to manufacture various high-temperature power equipment, such as transformers, motors, etc.

Automotive Industry: used for automotive wiring harnesses and battery cables due to their high temperature resistance and chemical corrosion resistance.

The Preparation Process Of XL-PE Usually Includes

Raw Material Selection: Select high-quality polyethylene resin and cross-linking agent. The molecular weight of the polymer plays a key role in achieving the desired strength and flexibility.

Mixed Extrusion: Ensure the uniformity of the material through high-temperature and high-pressure extrusion molding.

Vulcanization Cross-linking: Improve the insulation and mechanical properties of the material through heat treatment or chemical treatment.

Angreen is a professional cross-linked polyethylene manufacturer and trader. XL-PE is a cross-linked polyolefin XL-PO.

Polyethylene is a linear molecular structure that is easily deformed at high temperatures. The process of cross-linking polyethylene transforms it into a network structure. This structure provides enhanced resistance to deformation, making it ideal for pipe and tubing applications where durability is critical.

Types Of XLPE Materials（Modified Plastics）

XL-PE cross-linked polyethylene is safe to process and easy to use. The shelf life is moderate after adding resin, and there is no disadvantage of premature or late cross-linking; it does not affect the processing performance and use performance of the product；

XL-PE high-density cross-linked polyethylene is non-toxic, non-polluting, and non-irritating to the skin and eyes.
