Choose Aluminium Trihydrate for superior flame resistance
The key properties of Aluminium Trihydrate (ATH) include exceptional whiteness, good translucency, resistance to chemicals and weathering.
You might know Aluminium Trihydrate also as Aluminium Trihydroxide or Alumina Trihydrate.
This mineral is derived from Bauxite ore. This natural ore is refined to a fine white powder via the Bayer process. After washing and drying, it is used as the feedstock for a wide range of Alumina chemicals. The raw material used for the products is from a high-purity source.
Applications using ATH
Our international customers use this particular mineral for a variety of end-products, for example:
Solid surfacing
Fire retardancy in coatings
Flame retardancy in polymers
For the latter two applications, we also offer our UltraCarb product. To understand which mineral is the best solution for your process, we advise you to contact your area sales manager.

Aluminium Trihydrate (ATH) FAQs
LKAB Minerals offers Aluminium Trihydrate in various grades, including different particle sizes and surface-modified options, allowing it to be tailored for applications such as flame retardant systems, coatings, and solid surface production.
Particle size directly affects properties like surface finish, dispersion, and mechanical strength. Fine grades improve smoothness and aesthetics, while coarser grades can enhance processing efficiency and reduce formulation costs.
Yes, ATH is widely used in cable compounds due to its ability to release water vapour when heated, helping to reduce flame spread and minimise smoke generation in fire scenarios.
ATH is a primary filler in solid surface materials, providing brightness, opacity, and consistent processing behaviour, which are essential for high-quality finishes.
ATH can increase stiffness and dimensional stability in polymers. However, high loading levels may impact flexibility, so formulations are typically optimised to balance performance and processability.
Proper dispersion is critical to achieving optimal performance. Processing temperatures must also be controlled, as ATH begins to release water at elevated temperatures, which can affect manufacturing outcomes if not managed correctly.
ATH is a halogen-free flame retardant and is widely used in formulations designed to meet environmental and safety standards, particularly where low toxicity and reduced smoke emissions are required.
ATH is typically supplied as a dry powder and can be delivered in bulk or bagged formats. It should be stored in dry conditions and handled with appropriate dust control measures to maintain product quality and workplace safety.
