ALUMINA TRIHYDRATE MARKET OVERVIEW

The global Alumina Trihydrate market size was USD 1.589 billion in 2025 and is projected to touch USD 1.987 billion by 2033, exhibiting a CAGR of 3.8% during the forecast period.

Alumina trihydrate (ATH) is a low-cost, strategic inorganic compound with wide application in the polymer industry as a flame retardant in the absence of halogen and as a smoke suppressor. The global production of Alumina Trihydrate is in the vicinity of 100 million tons per year, wherein nearly all of it is produced along with the Bayer process. The Bayer process is the process under which the Bauxite (Aluminium Ore) is exposed to sodium hydroxide and dissolved at a high temperature. Alumina Trihydrate is subsequently extracted from the solids that have been left over after the heating process. The solids left behind once the Alumina Trihydrate is eliminated are very toxic and pose an environmental problem. This means that more than 90 percent of the total amount of Alumina Trihydrate that is produced is turned into Aluminium Oxide (alumina), which is utilized in the production of aluminum. Alumina Trihydrate is used as a flame-retardant chemical and added to a polymer molecule or mixed into a polymer in a controlled amount to suppress and decrease the spreading of the flame within a plastic. Alumina Trihydrate is also a kind of antacid that is consumed in order to neutralize the PH of the stomach.

ATH has specific characteristics, which make the market favorable, such as its water vapor-releasing features when the compound is subjected to high temperatures, diluting flammable gases, and making it useful in fire protection. Due to the growing importance of safety regulations and environmental compliance in all industries, ATH has become an attractive alternative to classical halogenated flame retardants because of its non-toxicity and superior performance properties. The versatility of the compound is not limited to the flame retardancy, with applications including use in electronics as a filler agent, in chemical processes as a source of raw materials, and in a minute but wide range of industrial uses where the high thermal stability/fire resistance is of priority. In the alumina trihydrate market, significant technological improvements in the optimization of the particle sizes and the nature of the treatment on the surfaces are being experienced, which have allowed the industry to reach the potential of performance in specific applications.
