Flame Retardant for LSHF Cables | Halogen Free Flame Retardant

Flame Retardant for LSHF Cable

Non-toxic inorganic flame retardant for low smoke halogen free cables and wires

This inorganic flame retardant is specially designed for use in low smoke halogen-free (LSHF) cables and wires. Developed in collaboration with the Spanish National Research Council in Madrid, this additive offers non-toxic fire protection suitable for a variety of cable applications. The flame retardant is available in different grades, including the HM-2 and HM-2S series, which are optimized based on particle size and surface treatment.

How It Works

During combustion, this flame retardant releases crystallized water at temperatures between 100-200°C and continues to do so at 300-400°C. This process helps cool the material, lower the combustion temperature, and slow down the spread of fire. At the same time, it forms a protective layer that reduces the supply of oxygen, further inhibiting the fire and suppressing smoke without releasing harmful gases.

Features

Made from high-purity magnesium-based minerals, this flame retardant offers effective fire protection while maintaining the integrity of the material
When exposed to heat, it releases crystallized water and carbon dioxide, reducing fire spread by cooling the material and lowering the combustion temperature
During combustion, it creates a protective char layer that blocks oxygen from fueling the fire, significantly slowing down the spread of flames and smoke
Precisely ground for improved dispersion and compatibility, ensuring smooth integration into various materials without affecting their physical properties
A sustainable, halogen-free flame retardant derived from natural minerals, offering a safer, eco-conscious alternative without compromising performance

Applications

Primarily used in low smoke halogen-free cables and rubber insulation products, this flame retardant ensures both safety and performance in industries where fire resistance is critical
