By Type, aluminum hydroxide dominates on cost and performance

The aluminum hydroxide emerged dominant among types in the year 2025, accounting for about 72% of the total revenue share. Wide-ranging use cases, low cost, and effective flame retardancy features all contribute to the dominance of this material. The construction, electrical and electronics, and automotive sectors mainly use this material due to the following benefits: excellent thermal stability, low toxicity, and smokes suppression. Thermal decomposition of the material at 180 to 200 degrees Celsius releases water vapor, resulting in surface cooling effect. This feature helps prevent the spread of flames within a wide range of polymer blend materials. In addition, the aluminum hydroxide is easier to obtain and cheaper than the organophosphorus retardants. The particle size optimization helps improve the dispersion of this material within various polymer matrices. The ongoing regulations against the halogenated flame retardants will ensure that this material maintains its prominent position.

The organophosphorus flame retardants form the main alternative products in the type category. Synthetic processes used in manufacturing these products are complicated and costly. Manufacturers still produce the organophosphorus materials for specific application requirements. The increasing demand for engineering plastics with higher performance levels increases the importance of this category of flame retardants.

By Application, polyolefins dominate on cost and processability

Polyolefin was the leading application type in 2025, accounting for about 28% share in total revenue generation. Industries such as packaging, construction, automobiles, and electrical & electronics depend greatly on these materials. Polyethylene and polypropylene are among the most common polyolefins due to their economical nature. Light weight and ease of processing are other factors that have increased the usage of these materials. As the polyolefin is combustible, halogen-free flame retardants are mandatory for fire resistance requirements. Increasing demand for green flame-retardant products in wire & cables, and roof industries strengthens this segment. Key players in the market have been constantly working on producing new halogen-free products for this segment.

The applications such as engineering thermoplastic and other special applications are emerging along with electronics & EV. These applications often need the flame retardants that can cope with stringent mechanical and thermal properties. The miniaturization of the electronic devices has increased the chance of overheating in compact devices. With increasing production of advanced electronics and electric vehicles, demand in these applications will be high.
