Alumina Trihydrate Market Report 2026

The alumina trihydrate market size has grown strongly in recent years. It will grow from $2.25 billion in 2025 to $2.39 billion in 2026 at a compound annual growth rate (CAGR) of 6.4%. The growth in the historic period can be attributed to growth in aluminum production, rising demand for flame retardant materials, expansion of plastics and polymer industries, increased use of fillers in paints and coatings, availability of bauxite reserves and refining capacity.

The alumina trihydrate market size is expected to see strong growth in the next few years. It will grow to $3.03 billion in 2030 at a compound annual growth rate (CAGR) of 6%. The growth in the forecast period can be attributed to increasing fire safety regulations across industries, growing demand for halogen-free flame retardants, expansion of construction and infrastructure activities, rising consumption of plastics in electrical and electronic applications, technological advancements in alumina processing. Major trends in the forecast period include rising use of alumina trihydrate as a halogen-free flame retardant, increasing demand for high-purity and fine-particle grades, growing adoption of alumina trihydrate as a functional filler in plastics, expansion of usage in building and construction materials, increasing focus on consistent particle size and product quality.

The growing demand for flame retardants within the construction industry is anticipated to drive the growth of the alumina trihydrate market. With the rise in commercial and residential developments, the risk of explosions and fire-related incidents has also increased. Non-halogenated flame retardants work by forming a protective char in the condensed phase or releasing free radicals upon ignition, which helps slow the spread of fire. In response to heightened fire safety concerns, many countries have implemented stringent fire safety regulations and protocols. Consequently, to comply with these government mandates, there is a growing use of non-flammable retardants in construction, thus boosting the demand for alumina trihydrate. For instance, in June 2024, TST Europe, a Switzerland-based manufacturer specializing in quick-release couplings and coupling systems, reported that total construction spending in the U.S. reached $1.98 trillion in 2023, reflecting a 7.4% increase from the previous year. As of 2023, there were approximately 745,000 construction businesses operating in the U.S. Therefore, the rising demand for non-halogenated flame retardants is propelling the growth of the alumina trihydrate market.

Major players in the alumina trihydrate market are concentrating on strategic investments, particularly in the development of advanced manufacturing facilities. For example, Hindalco Industries, an India-based mining company, is expanding its production capacity for high-quality aluminum foil. The company plans to invest ₹800 crores to establish a new facility near Sambalpur in Odisha, which will initially produce 25,000 tonnes of durable material essential for Lithium-ion and Sodium-ion cells. By 2030, the demand for battery-grade aluminum foil in India is expected to rise significantly to 40,000 tonnes, driven by the rapid growth of gigafactories dedicated to advanced cell production.

In August 2023, Cimbar Resources Inc., a US-based mining company, acquired the specialty alumina manufacturing assets of Almatis, Inc. located in Rocky Face, GA, for an undisclosed amount. This acquisition strengthens Cimbar's alumina trihydrate portfolio by improving product quality and ensuring supply continuity from multiple locations, which allows for consistent delivery to customers. Almatis, Inc. is a Germany-based chemical manufacturing company that specializes in producing alumina trihydrate.
