Low Smoke Zero Halogen Crosslinked Polyolefin

What is Low Smoke Zero Halogen Crosslinked Polyolefin/What is LSZH XLPO?

Low-smoke Zero halogen cross-linked polyolefin（LSZH XLPO）is a polyolefin material that has been treated through a cross-linking process that removes halogen elements and adds specific flame retardants. It combines the excellent mechanical properties of cross-linked polyolefin with the environmental characteristics of low-smoke, halogen-free materials, and is widely used in demanding cable applications.

Low Smoke Zero Halogen Cross-linked Polyolefin Features

1.Low Smoke Emission

Low-smoke halogen-free cross-linked polyolefin releases a very low concentration of smoke during combustion, and at the same time, the transparency of the smoke is high. This provides better visibility in fire situations and reduces obstruction to evacuation and rescue.

2. No Halogen Toxicity

Unlike traditional halogen-containing materials, low-smoke halogen-free cross-linked polyolefins do not release halogen-based toxic gases during combustion. This avoids the production of corrosive gases (such as hydrogen chloride), thereby reducing the hazards to equipment, personnel and the environment.

3. Excellent Flame Retardancy

Through the cross-linking process and the addition of flame retardants, low-smoke halogen-free cross-linked polyolefin has excellent flame retardant properties, which can effectively prevent the spread of flame, and can meet the requirements of UL94 V-0 and other high standards of flame retardancy.

4. Excellent Mechanical Properties

The cross-linked structure makes the material maintain stable performance under temperature change and external force. Low-smoke halogen-free cross-linked polyolefin has good resistance to high temperature, aging, wear and other characteristics, can be used for a long time in harsh environments.

5. Excellent Electrical Insulation Properties

Cross-linked polyolefin materials have very high electrical insulation properties, suitable for high-voltage cable insulation and sheath materials, in the electric power, communications and other industries have a wide range of applications.

Main Application Areas of Low-smoke Zero halogen Cross-linked Polyolefin Materials

Low-smoke Zero halogen cross-linked polyolefin has been widely used in many industries due to its excellent environmental performance and safety.

The following are some of the major application areas:

1. Building Cables

Low-smoke halogen-free cross-linked polyolefin is commonly used in the sheath and insulation of building cables. Since the building environment is usually crowded and fire accidents may cause serious consequences, the selection of low-smoke halogen-free materials can greatly improve safety in the event of a fire and reduce the speed of fire spread and the concentration of smoke.

2. Rail Transportation

Cables used in transportation facilities such as subways, high-speed railroads and light railways require strict safety standards. Low-smoke halogen-free cross-linked polyolefin cables are not only flame retardant, but also reduce the release of smoke and toxic gases to ensure personnel safety.

3. Communication Cables

Communication system cables require high stability and high security, low smoke halogen-free cross-linked polyolefin electrical properties and weathering performance makes it the ideal material for communication cables. Especially in high-frequency signal transmission cables, low-smoke halogen-free cross-linked polyolefin can effectively ensure the stability and safety of the signal.

4. Data Centers And Computer Networks

Data centers have strict requirements for flame retardant cables and low smoke, especially in the environment of large-scale server operation. Low-smoke halogen-free cross-linked polyolefin cables can effectively ensure the electrical safety of data centers and personnel health, reduce the losses caused by fire.

5. New Energy And Photovoltaic Cables

With the rapid development of the new energy industry, low-smoke halogen-free crosslinked polyolefin is widely used in new energy cables and photovoltaic cable insulation and sheath. The material has good UV resistance and high temperature resistance, suitable for long time use in harsh outdoor environments.

Technical Advantages of Low-smoke Zero halogen Cross-linked Polyolefin

Compared with other materials, low-smoke halogen-free cross-linked polyolefin has a number of technical advantages, the following are its main advantages:

1. Environmental Protection And Safety

As a halogen-free material, low-smoke halogen-free cross-linked polyolefin does not release toxic gases during combustion, avoiding the hazards that traditional cable materials may cause to the environment and personnel. In addition, its low smoke characteristics further improve safety in case of fire.

2. High Temperature And Aging Resistance

The cross-linking process gives the low-smoke halogen-free polyolefin material high temperature resistance and anti-aging ability, can be used for a long time in high temperature or extreme weather conditions without performance degradation.

3. Stretch And Abrasion Resistance

Low-smoke halogen-free cross-linked polyolefin has high mechanical strength and abrasion resistance, suitable for demanding industrial environments, can resist external pressure and friction, to extend the service life of the cable.

4. Excellent Electrical Performance

Low-smoke halogen-free cross-linked polyolefin has very good electrical insulation properties to ensure electrical safety during power transmission.

5. Various Processing Methods

The material can be produced through a variety of processing methods, such as extrusion, injection molding, etc., to adapt to different specifications and requirements of the cable product manufacturing.
