As industries worldwide prioritize fire safety and environmental responsibility, Low Smoke Zero Halogen (LSZH) material has emerged as a game-changing polymer solution. ATP Polymer Technology Co., Ltd., a leading innovator in sustainable polymer compounds, specializes in high-performance LSZH formulations that combine superior flame retardancy with minimal toxic emissions. Founded in 2007 and backed by a CNAS-certified R&D team, ATP produces eco-friendly LSZH materials that comply with EU CPR and GB31247 flame retardancy standards, making them indispensable in rail transit, data centers, aerospace, and medical applications.
Unlike traditional halogen-containing polymers (e.g., PVC), LSZH materials significantly reduce smoke density and toxic gas emissions during combustion—ensuring safer evacuations and reducing environmental hazards. With 12,000 tons of annual production capacity, ATP ensures reliable, high-quality LSZH solutions for industries where safety is non-negotiable.
The superiority of low smoke zero halogen material stems from its unique chemical composition, which prioritizes human safety and environmental protection:
Near-Zero Smoke Emissions – Unlike conventional materials, LSZH produces <5% smoke density during fires, improving visibility for safe evacuations.
Halogen-Free Composition – Eliminates toxic acid gases (HCl, HBr) formed by burning PVC, ensuring safer air quality in confined spaces.
Self-Extinguishing Properties – ATP's LSZH formulations exceed UL94 V-0 & IEC 60332 flame retardancy standards for maximum fire resistance.
Eco-Friendly Compliance – Fully conforms to RoHS, REACH, and EU CPR regulations, making them ideal for green building projects.
High Mechanical Strength – Retains resilience and flexibility even in extreme conditions (–40°C to 120°C).
These properties make LSZH material the top choice for subways, hospitals, and naval applications, where halogen-free flame retardancy is critical.
ATP's low smoke zero halogen material is reshaping industrial safety standards with applications in:
Rail & Public Transportation
Subway and high-speed rail power cables.
Tunnel lighting and signaling systems.
Telecommunications & Data Centers
Fiber-optic / 5G network cabling (reducing fire risks in server farms).
Building & Construction
Safety-critical wiring for hospitals and high-rises.
Smart building automation systems (complying with GB31247).
Military & Aerospace
Flame-retardant aircraft and naval shipboard cables.
Renewable Energy
Solar and wind farm cabling (UV-resistant LSZH formulations).
With ATP's industry-leading R&D, LSZH materials bridge the gap between compliance and high performance, ensuring zero compromises on safety.
To illustrate the safety advantages of low smoke zero halogen material, below is a performance comparison with standard alternatives:
Property | LSZH Material | PVC (Halogenated) | XLPE (Cross-linked PE) |
Smoke Emission | Very Low (<5% opacity) | Extremely High (thick smoke) | Moderate |
Toxic Gas Release | Zero Halogens (no HCl) | High (HCl gas lethal at 1000ppm) | Low (but present) |
Flame Retardancy | UL94 V-0 / IEC 60332 certified | Requires additives | Moderate (less effective) |
Environmental Impact | RoHS/REACH-compliant | Contains phthalates | Contains stabilizers |
Durability | Excellent (flexible & abrasion-resistant) | Flexible but degrades | High temp resistant |
ATP's LSZH formulations clearly outperform PVC and XLPE in fire safety, making them the superior choice for confined and high-risk environments.
The low smoke zero halogen material market is evolving with stricter regulations and greener material demands:
Bio-sourced LSZH compounds for carbon-neutral infrastructure.
Enhanced thermal stability for EV battery cabling.
Smart LSZH materials with embedded fire-detection sensors.
With ATP's CNAS-accredited laboratory, the next generation of LSZH materials will set higher benchmarks in safety and sustainability for global industries.
Low Smoke Zero Halogen material represents the pinnacle of fire-safe polymers, offering unmatched safety, regulatory compliance, and environmental benefits. As halogen-free regulations expand worldwide, ATP Polymer Technology Co., Ltd. remains at the forefront of LSZH innovation, delivering high-performance, sustainable solutions for industries where fire safety matters most.
For rail networks, data centers, and smart cities, ATP's LSZH formulations ensure that advanced polymer technology aligns with uncompromising safety standards, driving the future of fire-resistant materials.
