LSZH

LSZH wire material

What Is A LSZH Material？

LSZH, or Low Smoke Zero Halogen, is a wire sheathing material used in the wire and cable industry that is characterized by low smoke emission when heated or burned and is halogen-free. Cables made of this material do not release hydrogen halide or other acids when they catch fire, thus reducing the amount of toxic and corrosive gases produced during combustion.

In the selection of wires and cables, LSZH materials are often used in the manufacture of jackets and insulation to ensure that the cables do not become a source of toxic fumes and gases in the event of a fire. The development and application of these materials is an important contribution to the cable industry's efforts to improve safety and environmental protection.

Angreen has developed polyolefin flame retardant materials (LSZH) specifically to meet the high flame retardancy and high safety requirements of cables, optical cables and network cables. Compared with traditional polyolefin flame retardant materials, LSZH materials have undergone longer research and development and more comprehensive and rigorous comprehensive performance tests. It has been comprehensively improved in raw material selection, formula design, flame retardant system compounding innovation, lubrication system innovation and production process control. It is a new upgraded version of traditional LSZH materials.

Product Features

More Reliable Flame Retardant Performance: can be used to manufacture optical cables, cables and network cables, etc., and support passing EN50575 and GB31247 combustion tests

Higher Safety: supports cables to pass UL758/1581 105℃ temperature resistance test (136℃/168Hrs)

Better Wear Resistance: more than 50,000 wear tests effectively avoid wear and cracking

Better Processing Performance: high-speed extrusion, long-term stable processing, no drooling, skin breakage, particles and other defects

Application Areas

Angreen's low-smoke halogen-free materials are widely used in the manufacture of cables, optical cables and grid lines in the fields of photovoltaic cables, home decoration cables, rail transportation, etc.

Flame-retardant polyolefin LSZH cable material is a special type of cable material that combines the excellent physical properties of polyolefins with the environmental protection characteristics of LSZH (Low Smoke Zero Halogen). This material produces less smoke when burned and does not contain halogen, so it does not produce toxic gases. It is particularly suitable for occasions with high safety and environmental protection requirements, such as subways, high-rise buildings, ships, oil platforms, etc.

The performance requirements of LSZH cable materials vary depending on the application, including tensile strength, elongation at break, aging temperature, volume resistivity, oil resistance, scratch resistance, softness and flame retardancy requirements. These performance indicators need to be optimized according to different cable types and usage environments.

In general, LSZH cable materials have broad application prospects in the wire and cable industry due to their excellent flame retardant properties and environmental protection characteristics.
