Aluminum Hydroxide ATH (Al(OH)₃)

Aluminum Hydroxide ATH (Al(OH)₃) is a halogen-free mineral flame retardant and smoke suppressant used in HFFR cable compounds, plastics and rubber. When exposed to heat, the material absorbs thermal energy and releases water vapour, helping cool the material and reduce the concentration of combustible gases. Its use supports flame-retardant formulations where smoke reduction and electrical insulation are relevant considerations.

What is Aluminum Hydroxide ATH used for?

Aluminum Hydroxide ATH is used in HFFR cable compounds, plastics and rubber to help reduce flame propagation and smoke generation. In cable formulations, its relevance includes electrical insulation applications; the appropriate formulation depends on the compound and the intended use.

ATH functions as a halogen-free mineral additive. Heat absorption and water-vapour release are central to its flame-retardant action, so formulators assess its role alongside the required flame and smoke performance of the finished compound.

• HFFR cable compounds: Consider ATH when developing halogen-free cable formulations that require flame-retardant performance.
• Plastics and rubber: Evaluate the additive in the context of the intended product and its processing conditions.
• Electrical insulation: Confirm that the selected formulation meets the requirements of the specific insulation application.

How do you select and process Aluminum Hydroxide ATH?

Selection starts with the application and its processing temperature. ATH is suited to low- and medium-temperature processing, so compare the compound’s processing conditions with the material’s technical data before making a selection.

Formulation decisions involve balancing flame-retardant and smoke-suppression needs against the processing requirements of the finished compound. Check the technical data sheet for the available product grade and relevant processing information, then assess the material in the intended formulation rather than relying on a general application description.

• Match the use: Choose a formulation route based on whether the target is a cable compound, plastic or rubber product.
• Check processing conditions: Confirm that the application fits the stated low- and medium-temperature processing suitability.
• Verify performance: Review the technical data and test the compound against the flame, smoke and insulation requirements of the end use.

What documentation or sample should you request?

A technical data sheet helps a formulation team review product details and processing suitability, while a safety data sheet supports safe handling decisions. Request both documents for the grade under consideration, and use a sample to assess the material in the intended compound where a formulation trial is required.

Product-specific values and other details should be confirmed on the technical data sheet rather than assumed from the material name. The safety data sheet provides the relevant safety information for evaluating and handling the product.
