What Is LSZH Low Smoke Zero Halogen Materials?

Low Smoke Zero Halogen LSZH materials are high-performance flame-retardant materials composed of polyolefin blend resins mixed with flame-retardant hydroxide fillers, and they do not contain halogen elements. LSZH materials produce minimal smoke when burned and are free from halogens, making them safer in fire situations by reducing the generation of toxic smoke, thereby enhancing escape and rescue possibilities.

·Low Smoke Zero Halogen LSZH compounds are widely used as cable sheathing materials globally.

·LSZH stands for "Low Smoke Zero Halogen" a commonly used halogen-free flame-retardant material in cable sheathing.

·LSZH materials produce little smoke, are low in toxicity, and have minimal corrosiveness, demonstrating excellent fire safety performance.

·LSZH cables are commonly used in densely populated areas such as office spaces and public transportation systems.

Since 2011, Angreen has been developing low smoke halogen-free (LSOH) materials for various applications, including B1 cables, rail transit, building decoration, and data communication, in accordance with the requirements of the CRP (Construction Products Regulation) in Europe.
Angreen's low smoke halogen-free materials support cable compliance with CPR EN50575 classifications (B2ca, Cca, Dca, Eca) for burning tests.
LSZH sheath materials feature higher flame-retardant ratings and drop test ratings, exhibiting excellent processing characteristics and quality even under high flame-retardant performance.

Angreen's high-voltage Low Smoke Zero Halogen cable material solutions fully meet the low-friction LSZH requirements for temperature resistance and flame retardancy in high-voltage harnesses, satisfying ISO 6722 at 125℃.

Applications of Low Smoke Halogen-Free LSZH Materials

B1 Class Cables: B1 flame-retardant cables for public places such as hospitals, schools, and offices.

Communication Cables and Fiber Optic Cables: Used to reduce fire risk in applications such as computers, communication equipment, and servers.

Rail Transit Cables: Used to improve passenger safety in applications such as airplanes, trains, and automobiles.

Low Smoke Halogen-Free (LSZH) compounds are widely used in cable sheaths. Cable manufacturers not only need materials that meet basic safety, flame retardancy, and mechanical performance standards, but also require greater cost-effectiveness in large-scale production.

Angreen's Low Smoke Zero Halogen Materials Fully supports fiber optic cables, power cables, and network cables in passing EN 50575 (B2ca, Cca, Dca) and GB31247 (excluding A) fire tests (different product names meet different fire test levels).

High Flame Retardant LSOH

High flame retardant low smoke zero halogen (LSOH) material is a flame retardant polymer specially used for cable insulation with excellent fire resistance. It provides higher safety protection for the application environment by resisting combustion, reducing smoke generation, and avoiding the release of toxic halogen gases.

Low Smoke Zero Halogen Cable material

UL Certified LSZH Flame Retardant Cable Material is a low-smoke, halogen-free solution that enhances safety by reducing toxic gas emissions during fires. Ideal for high-risk environments like subways and oil platforms, it offers superior flame resistance, wear durability, and processing performance for cables and optical fibers.

B1 Irradiation Cross-linked LSZH Flame Retardant Jacket Material

Class B1 cable material is a highly flame retardant cable material that does not release toxic gases when burned. It is often used in places with large traffic such as indoors, offices, public places, and schools. It has the characteristics of being flame retardant and smoke-free.

Silane Crosslinking LSZH

Silane cross-linked low-smoke halogen-free flame-retardant polyolefin cable material is very convenient to use. It can be quickly cross-linked under warm water boiling conditions, or it can be naturally cross-linked at room temperature.

LSZH Optical Cable Material

LSZH Optical Cable Material is a special modified plastic material with environmental protection and safety as its core. It is widely used in the sheath and insulation layer of modern fiber optic cables for its excellent characteristics of low smoke density and no release of halogen harmful gases during combustion. Its compliance with environmental regulations and high performance make it one of the preferred materials in the communication, electric power and rail transportation industries.

HFFR Cable Compound

HFFR cable material refers to a Halogen-Free Flame Retardant material that is typically used in the sheath or insulation of cables. Compared with traditional halogen-containing materials, HFFR cable material does not contain toxic halogen elements such as chlorine and bromine, which prevents it from releasing harmful corrosive gases such as hydrogen chloride or bromide during a fire.HFFR cable material effectively inhibits the spread of flames during combustion and reduces the release of hazardous fumes, which safeguards the safety of people and environmental protection.

LSZH Cross-linked Polyethylene

Low Smoke Zero Halogen Crosslinked Polyethylene (LSZH XLPE) is a polyethylene material modified by a crosslinking process and formulated without halogen elements. It combines the excellent electrical properties of polyethylene with the high heat resistance of a crosslinked structure and the environmentally friendly properties of low smoke and zero halogen. Low smoke zero halogen crosslinked polyethylene can not only work stably under high temperature environment, but also release minimal toxic gases in fire, reducing the environmental pollution and danger in case of fire.

LSZH Polyethylene

Low-smoke Zero halogen polyethylene is a specially modified polyethylene material with halogen elements removed and specific flame retardants added to its chemical structure. Unlike traditional halogen-containing materials, low-smoke halogen-free polyethylene not only releases less smoke when it burns, but also does not release toxic halogen gases, which is in line with environmental and safety requirements.

LSZH Crosslinked Polyolefin

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.

LSZH Polyolefin LSZH PO

Low Smoke and Halogen Free Polyolefin (LSZH PO) is a polymer material made by modifying a polyolefin, such as polyethylene or polypropylene, by removing halogen elements and adding flame retardant fillers. This material is ideal for modern cable jacketing and insulation due to its low toxicity, low smoke characteristics and excellent flame retardancy.

HFFR Polyolefin B2 Cable Material

LSZH flame retardant B2 cable sheath material is a halogen-free, low smoke, flame retardant polyolefin material with excellent heat resistance and mechanical properties, making it ideal for use in high-rise buildings, subways, power plants and rail transit. This material reduces toxic gas emissions, improves safety in the event of a fire, and complies with national safety standards.
