In an era where fire safety and environmental protection are paramount, Low Smoke Zero Halogen material has become essential for cables and wiring in sensitive environments. As a global leader in polymer compounds, ATP Polymer Technology specializes in high-performance LSZH solutions that meet stringent EU CPR, GB31247, and international safety standards.
This article explores what LSZH material is, its advantages over conventional materials, key applications, and why ATP's LSZH stands out in safety and performance.
Low Smoke Zero Halogen material is a specialized polymer compound designed to minimize toxic emissions and smoke when exposed to fire. Unlike traditional PVC and halogenated materials, LSZH contains no chlorine, fluorine, or bromine, preventing the release of corrosive and poisonous gases in high-temperature conditions.
Key characteristics of LSZH include:
Minimal smoke emission for better visibility during emergencies.
Zero toxic halogens, protecting both humans and equipment.
Self-extinguishing flame retardancy.
Environmental compliance (RoHS, REACH, and EU CPR).
ATP Polymer Technology employs advanced compounding techniques to enhance LSZH performance, ensuring optimal durability, flexibility, and fire resistance.
Traditional PVC and halogenated cables pose significant risks due to their combustion byproducts—hydrogen chloride, dioxins, and dense smoke. These substances not only impair evacuation efforts but also damage electronic equipment and harm respiratory health.
In contrast, ATP's LSZH materials offer:
Safer evacuation (up to 90% less smoke compared to PVC).
No toxic gas emissions, ideal for confined spaces like subways, tunnels, and hospitals.
Longer circuit integrity during fires (critical for emergency lighting and alarms).
Comparison Criteria | PVC & Halogenated Materials | ATP's LSZH Materials | Key Benefits of LSZH |
Smoke Emission | Produces dense, obscuring smoke | Up to 90% less smoke than PVC | Clearer visibility during fires for safer evacuation |
Toxic Gas Release | Emits hydrogen chloride, dioxins, and other corrosive gases | Zero halogen content – no toxic fumes | Safer for humans (no respiratory damage) and electronics (no corrosive degradation) |
Fire Regulations Compliance | Often banned in rail transit, tunnels, and hospitals | Meets EU CPR, GB31247, and other strict fire safety standards | Mandatory for modern infrastructure (e.g., subways, data centers) |
Circuit Integrity During Fire | Melts quickly, causing short circuits | Maintains functionality longer under fire conditions | Critical for emergency alarms, lighting, and medical equipment |
Real-World Adoption | Being phased out in high-risk environments | Preferred in rail systems, smart buildings, and EVs | Proactively avoids fire-related liabilities and health hazards |
A real-world example is the increasing adoption of LSZH in rail transit systems—where fire safety regulations strictly prohibit PVC-based cables due to their hazardous fumes.
Thanks to its safety advantages, LSZH is widely used in:
Public Transportation & Infrastructure
Metro systems, airports, and railway stations require low-smoke cables to ensure passenger safety.
Telecommunications & Data Centers
High-speed 5G and fiber optic networks rely on LSZH to prevent corrosive damage from fire incidents.
Energy & EV Charging Stations
With strict fire regulations, EV battery cables and charging infrastructure increasingly use LSZH materials.
Military & Aerospace
LSZH's flame resistance and low toxicity make it ideal for defense and aviation wiring.
Medical & Smart Buildings
Hospitals and smart buildings demand safe, non-toxic cabling for critical systems.
ATP Polymer's customized LSZH formulations meet the unique needs of these industries, including enhanced flexibility for tight wiring spaces and improved UV resistance for outdoor use.
As a CNAS-certified polymer innovator, ATP combines cutting-edge research with rigorous testing to develop the next generation of LSZH materials. Key advancements include:
