Segmental Insights
Why Does Reactive Flame Retardants Dominate the Global Reactive PU Flame Retardants Market?
The reactive flame retardants segment is expected to account for 57.0% of the global reactive PU flame retardants market share in 2026. Reactive flame retardants dominate because they become chemically integrated into polyurethane polymer structures during manufacturing. The covalent bonding decreases the migration, leaching and chemical loss during long-term product use. This incorporation enhances flame-retardant longevity while keeping material performance. Furthermore, reactive formulations are more compatible with polyurethane matrices than conventional additives. Incorporating them can reduce negative impacts on mechanical qualities. Rising need for robust, low emission and halogen-free polyurethane materials further boosts adoption.

Why is Phosphorus-Based Reactive Flame Retardants the Most Crucial Chemistry?
The phosphorus-based reactive flame retardants segment is expected to account for 44.0% of the global reactive PU flame retardants market share in 2026. Phosphorus-based reactive flame retardants are important because they provide efficient fire protection by several combustion-control methods. They encourage the development of a protective char that restricts heat transfer and the emission of flammable gasses. Some phosphorus compounds also form phosphorus containing radicals, which inhibit the combustion reactions. Their chemical incorporation enhances the retention of flame retardants in the structures of polyurethanes. The use of halogen-free formulations further aids their adoption in applications with high environmental criteria. The growing interest in sustainable polyurethane materials is driving the need for phosphorus-containing polyols. These qualities make phosphorus chemistry very relevant in rigid and flexible polyurethane foams.
On February 6, 2026, the product information for Clariant’s Exolit OP 552 was updated. The non-halogenated phosphorus polyol is for flexible polyurethane foams. Its reactive reactivity allows it to become incorporated in the polyurethane matrix, thus minimizing flame retardant migration. Clariant identifies automotive slabstock and molded foam as application areas.
Liquid Dominates the Global Reactive PU Flame Retardants Market
The liquid segment is expected to account for 52.0% of the global reactive PU flame retardants market share in 2026.

Liquid products offer the convenience of blending, precision dosage and equal dispersion within polyurethane combinations. Compatibility with existing processing equipment means less need for formulation tweaks and less manufacturing complexity. Liquid phosphorus polyols can directly engage in polyurethane chemical processes. This incorporation enhances consistency in formulation and preservation of flame retardant. easy handling for manufacturers and flexible formulation creation. The growing need for high-performance polyurethane foams also favor the use of liquid reactive flame-retardants.
On January 6, 2025, ICL announced the launch of VeriQuel R100, a reactive phosphorus flame retardant for rigid polyurethane insulation. The formulation is chemically bonded into the polyurethane matrix to provide long-term flame-retardant retention and reduce migration.
