Products Description
Melamine phosphate (MP) represents a high‑efficiency halogen‑free flame retardant. It is generally available as a white powder, with a molecular formula of C₃H₉N₆O₄P and a molecular weight of 224.12. It is sparingly soluble in water (3.9 g/L at 20 °C) and slightly soluble in methanol, and maintains favorable chemical stability under ordinary ambient conditions.
Primarily applied in plastics, coatings and textile substrates, melamine phosphate improves flame‑retardant performance. It suppresses fire propagation by releasing non‑flammable gases such as nitrogen and facilitating the creation of a protective char layer upon combustion.
