The Role of Aluminum Hydroxide in Cable Compounds: A Key to Flame Retardancy

In the modern world, fire safety is a top priority, especially in industries that rely on electrical systems. One of the most effective flame-retardant materials used in cable compounds is aluminum hydroxide (ATH). Due to its excellent fire-resistant properties and environmental benefits, ATH has become an essential additive in the production of cable insulation and sheathing materials.

Why Is Aluminum Hydroxide Used in Cable Compounds?

Flame Retardancy: ATH releases water molecules when exposed to high temperatures (above 200°C), which helps cool the material and slow down the spread of fire. This makes it an effective flame-retardant filler for cable compounds.

Low Smoke & Non-Toxicity: Unlike halogenated flame retardants, ATH decomposes without producing toxic gases or corrosive smoke. This property significantly enhances safety in enclosed spaces such as buildings, tunnels, and transportation systems.

Thermal Stability & Electrical Performance: ATH improves the thermal stability of cable materials, reducing the risk of degradation under high temperatures. Additionally, it maintains excellent electrical insulation properties, which is crucial for high-performance cable applications.

Environmental Friendliness: As a non-halogenated flame retardant, ATH aligns with global regulations on environmental protection and health safety, making it a preferred choice for sustainable cable production.

Applications in the Cable Industry

Aluminum hydroxide is widely used in various types of cable materials, including:

Low-smoke, halogen-free (LSHF) cables: Essential for public infrastructure, residential buildings, and transportation systems.

Power cables: Ensuring high fire resistance for electrical distribution networks.

Communication cables: Enhancing safety in data centers and telecommunication systems.
