Melamiinifosfaatin

Melamiinifosfaatti is a chemical compound with the formula C3H6N6·H3PO4. It is a salt formed from melamine and phosphoric acid. It typically appears as a white crystalline powder. Melamine is a nitrogen-rich organic compound known for its heat-resistant properties and use in resins. Phosphoric acid is a common inorganic acid.

The primary application of melamiinifosfaatti is as a flame retardant. When exposed to heat, it decomposes, releasing water and non-combustible gases like ammonia and nitrogen. These gases dilute the flammable gases in the air and cool the burning material, thereby inhibiting combustion. This property makes it useful in various materials, including plastics, textiles, and coatings, to improve their fire safety.

Melamiinifosfaatti is considered a halogen-free flame retardant, which is often preferred due to environmental concerns associated with halogenated flame retardants, such as the potential release of toxic byproducts during burning. Its effectiveness and relatively low toxicity contribute to its use in applications where fire safety is a critical requirement.
