As fire safety regulations tighten worldwide, industries are transitioning from conventional materials to advanced fire-resistant LSZH (Low Smoke Zero Halogen) compounds. Developed by ATP Polymer Technology, these innovative materials combine exceptional flame retardancy with minimal smoke and zero toxic gas emissions, making them indispensable for public spaces, transportation networks, and industrial applications. Unlike traditional PVC or halogenated materials, fire-resistant LSZH ensures life-saving performance in emergency situations while meeting the most stringent global safety standards.
Uncompromising Fire Safety Performance
Halogen-Free Composition – Eliminates toxic gas release (HCI, bromides) that endangers lives and equipment.
Ultra-Low Smoke Emission (Ds <60) – Maintains visibility for safe evacuation in confined spaces.
Self-Extinguishing Properties – Achieves UL94 V-0 flame retardancy, significantly reducing fire spread.
Regulatory Compliance for Global Markets
EU CPR (Construction Products Regulation) Certified.
Meets EN 45545 (Railways), IEC 60332-1/3 (Flame Spread), and UL 1685 (Vertical Flame Test).
China GB31247 (Flame Retardant Classification) & US NFPA Fire Codes.
Durability in Extreme Conditions
Resists mechanical stress, vibrations, and abrasion in industrial, automotive, and aerospace wiring.
Operating range: -40°C to 105°C – Suitable for harsh outdoor and indoor environments.
UV and chemical-resistant formulations for applications requiring long-term reliability.
