Irradiation Cross-linked Polyolefin XLPO Cable Materials

What is a XLPO Cross-linked Polyolefin?

XLPO, or Cross-linked Polyolefin, is a class of polyolefin materials modified by cross-linking, including polypropylene, polyethylene, and others.

Crosslinked Polyolefin It has excellent heat resistance, chemical resistance and electrical properties. one of the most important properties of XLPO is that it is halogen-free and therefore does not emit toxic gases when burned, which gives it a significant safety and environmental advantage.

XLPO materials are particularly important in cable insulation, where they can be used to make high-temperature-resistant electronic cables, New Energy Vehicle Cables, Charging Pile Cables, Photovoltaic Cables and other high-quality cable materials.

Photovoltaic cables made from XLPO materials can withstand temperatures as high as 250°C,making them suitable for applications that require high-temperature resistant environments.

XLPO material is suitable for applications that require high temperature resistance.

XLPO is a broader category than XLPE (cross-linked polyethylene), which is a type of XLPO that involves the process of transforming the linear molecular structure of polyethylene into a reticulated structure, either by radiation or chemical means.

XLPO compounds are tougher and more resistant to tearing, cutting and abrasion than silicones, allowing for greater flexibility while potentially reducing overall costs. In addition，XLPO is not subject to the same supply chain constraints that affect silicones, depending on the availability of silicon also used in microchips.

XLPO is 16 times more resistant to abrasion than silicone,2.5 times more resistant to tearing and four times more resistant to cutting.

Overall, XLPO occupies an important position in cable insulation, especially in areas such as electric vehicles and photovoltaic cables, due to its halogen-free properties and excellent physical properties.

Application Areas

This series of products is often used to manufacture high-quality cable materials for high-temperature resistant electronic wires, new energy vehicle cables, charging pile cables, photovoltaic cables, etc.

XLPO (cross-linked polyolefin) is a thermosetting material that includes polymers of various olefin monomers, such as ethylene, propylene, etc., and its performance is improved through the cross-linking process. XLPO material is particularly important in cable insulation because it does not contain halogens and therefore does not release toxic gases when burned, which has significant advantages in terms of safety and environmental protection.

XLPO is related to and different from XLPE (cross-linked polyethylene). XLPE is a type of XLPO, which is a process of transforming the linear molecular structure of polyethylene into a mesh structure through radiation or chemical methods. XLPE has excellent heat resistance, chemical resistance and mechanical properties and is suitable for high-voltage cable insulation. XLPE's heat resistance can not decompose below 300°C, the long-term working temperature can reach 90°C, and the thermal life can reach 40 years. At the same time, XLPE maintains the excellent insulation properties of polyethylene, the insulation resistance is increased, the dielectric loss tangent is very small, and it is not greatly affected by temperature.

XLPO materials are often used for insulators and sheath materials for photovoltaic cables because they do not release toxic gases when exposed to fire, which is crucial to improving the safety of cables. Photovoltaic cables made of XLPO materials can reach a temperature resistance of 250°C, which makes them suitable for applications that require high temperature resistance.

In general, both XLPO and XLPE are high-performance insulation materials that are widely used in cable manufacturing. XLPO is more popular in certain specific applications due to its halogen-free properties, while XLPE is widely used due to its excellent overall performance. Both are cross-linked processes that improve the performance of polyethylene or other polyolefins, but their chemical composition and application areas may differ.
