Low smoke zero halogen, referred to as LSZH, LSOH, LS0H, LSFH and OHLS, is the material classification of wire sheaths in the wire and cable industry. The low-smoke halogen-free wire sheath is composed of thermoplastic or thermosetting with low smoke emission when heated and no halogen itself.
LSOH material (low smoke halogen-free flame retardant polyolefin) is a special polyolefin material, its properties and uses are as follows:
Features:
1. Flame retardant: LSOH material has excellent flame retardant performance, which can inhibit the spread of flame during combustion and significantly reduce the flame propagation speed.
2. Low smoke characteristics: During combustion, LSOH materials produce less smoke, which helps to reduce the environmental pollution and the threat to personnel safety during fire.
3. Halogen-free characteristics: LSOH materials do not contain harmful substances such as halogens, and will not release toxic and harmful gases during combustion, which helps to reduce the harm to the surrounding environment and personnel.
4. Electrical performance: LSOH material has good electrical insulation performance, can provide stable electrical performance, and can withstand high voltage and high temperature environment.
5. Mechanical properties: LSOH material has high tensile strength and bending elastic modulus, which can withstand the mechanical stress of the cable during use. At the same time, its good wear resistance and fatigue resistance also make it suitable for cables that require frequent bending and friction.
6. Temperature resistance: LSOH material can maintain its stable performance in a wide temperature range and has good high temperature resistance. This allows it to adapt the cable to work for a long time in a high temperature environment.
Application:
1. Wire and cable: LSOH material is widely used in the wire and cable industry as the insulation layer and sheath layer of the cable. It can provide good electrical insulation properties, flame retardant properties and mechanical protection, while having the advantages of low smoke and halogen-free, helping to reduce the risk of fire and reduce pollution to the environment.
2. Other fields: In addition to the wire and cable industry, LSOH materials are also used in construction, rail transit, aerospace and other fields with high fire protection requirements. Its low smoke, halogen-free and flame retardant characteristics make it able to reduce the production of smoke and the release of toxic gases in the event of fire, ensuring personnel safety and environmental cleanliness.
In general, LSOH materials have excellent flame retardancy, low smoke characteristics, halogen-free characteristics, electrical properties, mechanical properties and temperature resistance, and have a wide range of application prospects in wire and cable and other fields with high fire protection requirements. Especially in the cable industry, LSOH material can significantly improve the safety performance and service life of cables, reduce the risk of fire, and is an ideal cable material choice.
