ATH Aluminium Trihydroxide natural mineral

Aluminium Trihydrate, also known as Aluminium Trihydroxide or Alumina Trihydrate, 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 ATH products is from a high purity source.

Important properties

ATH has the following properties important to most applications:

  • Exceptional whiteness
  • Good translucency
  • Resistance to chemicals and weathering
  • Impact resistance

The softness of the mineral contributes to making materials machinable with loading levels between 40% and 70% becoming possible and providing best properties.

ATH applications

  • ATH for solid surfacing

    Solid surfacing

    ATH is a key ingredient in the composite material referred to as solid surfacing (or artificial stone or synthetic marble/onyx). Solid surfacing that is widely used for kitchen, bathroom and laboratory counter tops benefits from the addition of ATH as it assists with most of the properties required for this material.

  • White paint roller

    ATH in polymers, coatings, adhesives and sealants

    ATH is also compatible with a wide range of polymer types e.g. in roofing membranes or for wire & cable or used in coatings for fire retardancy and because of its high whiteness. Within adhesives and sealants ATH also provides flame retardancy and additionally smoke suppression. Get more information on the dedicated industry uses pages by clicking on the link.
