Tris(tribromoneopenthyl)phosphate (often abbreviated to TTBNP) is a brominated organophosphate compound used primarily as a flame retardant. These compounds are often added to various materials to improve their fire resistance, especially in plastics, textiles, wire and cable insulation materials and electronic equipment.
As an additive flame retardant, TTBNP works in several ways:
Heat absorption: It breaks down at high temperatures and absorbs large amounts of heat, thus slowing down the combustion process.
Forming a protective layer: The material produced by decomposition can form a protective film on the surface of the material, isolating oxygen and reducing heat transfer.
Suppression of flame propagation: Through chemical reactions to consume the necessary free radicals in the combustion process, thus inhibiting the spread of the flame.
