Market Driver

Growth in Construction and Infrastructure Activities

The market is experiencing strong growth due to the rising demand from the construction and infrastructure industry. As more residential, commercial, and industrial projects are being developed across the Asia Pacific, the Middle East, and Latin America, the need for high-performance construction materials continues to grow. 

ATH is widely used in building products, such as sealants, insulation, and coatings, as a flame retardant and filler. With the construction sector focusing on fire safety and material durability, the use of ATH is becoming more common in infrastructure applications. The increasing reliance on ATH-based products in construction activities plays a key role in driving the market forward.

• In April 2025, according to the India Brand Equity Foundation, under the Union Budget 2025-26, the capital investment outlay for infrastructure reached USD 128.64 billion, accounting for 3.1% of India’s GDP.

Market Challenge

Limited Heat Resistance

One of the key challenges in the alumina trihydrate market is its limited heat resistance during processing. ATH starts to break down and release water at around 200°C, which makes it less suitable for high-temperature plastic manufacturing. This limits use with engineering plastics and other heat-demanding materials. 

Due to this, manufacturers opt for other flame retardants that can handle more heat, even if they are costlier or less environmentally friendly. A solution to the limited heat resistance of alumina trihydrate (ATH) is to combine it with other materials that have better heat resistance. 

By creating combined formulations, ATH can be enhanced to maintain its flame-retardant properties and improve its performance at elevated temperatures. Additionally, surface treatments or coatings can be applied to ATH particles to improve their heat resistance and dispersion in polymer matrices.

Market Trend

Increasing Use of Fine and Ultra-fine ATH Grades

In the market, the demand for fine and ultra-fine ATH grades is increasing. These grades are popular in high-performance applications such as advanced plastics, coatings, and cable compounds. Fine and ultra-fine ATH grades are known for their smaller particle size, which allows better dispersion, making them more effective in flame retardant applications. 

This leads to more consistent coverage and improved surface properties, which is crucial for industries that require precise and high-quality materials. As the need for efficient and high-performing products grows, the use of fine and ultra-fine grades of ATH is expected to grow, driving market growth.
