Is LSZH better than PVC?
https://www.sunualszh.com/lszh-sheath-compound.html
In the realm of cable manufacturing, the choice of sheath material is pivotal for safety and performance. Two prevalent options are Low Smoke Zero Halogen (LSZH) compounds and Polyvinyl Chloride (PVC). This article delves into the characteristics of LSZH sheath compounds, comparing them to PVC, and explores recent trends in their application.
Understanding LSZH Sheath Compounds
LSZH sheath compounds are formulated from halogen-free materials, primarily polyolefins, combined with flame retardants, antioxidants, and other additives. This composition ensures that, in the event of a fire, the cables emit minimal smoke and no halogenated gases, which can be toxic and corrosive. This property makes LSZH compounds particularly suitable for environments where human safety and equipment protection are paramount.

Comparing LSZH and PVC
PVC has been a longstanding choice in cable sheathing due to its durability and cost-effectiveness. However, when exposed to fire, PVC releases dense smoke and harmful halogen gases, posing risks to both individuals and electronic equipment. In contrast, LSZH compounds, while potentially higher in cost, offer enhanced safety by minimizing hazardous emissions during combustion. This trade-off has led many industries to reconsider their material choices, especially in safety-critical applications.
Recent Developments and Applications
The demand for LSZH compounds has surged across various sectors. In construction, rail transit, and data communication, the emphasis on fire safety and environmental sustainability has driven the adoption of LSZH sheathing materials. Manufacturers have responded by developing advanced LSZH compounds that not only meet stringent safety standards but also offer excellent mechanical properties and processability.

Conclusion
While PVC remains prevalent in various applications, the superior safety profile of LSZH sheath compounds makes them an increasingly preferred choice in environments where fire safety and reduced toxicity are critical. As industries continue to prioritize safety and environmental considerations, the adoption of LSZH materials is poised to grow, reflecting a broader commitment to protecting both people and infrastructure.
