Melagard MP is a halogen-free flame retardant and smoke suppressant based on a salt of melamine and phosphoric acid. It is designed for use in thermoplastics, polyolefins, elastomers, engineering resins, paints, and intumescent fire retardant coatings. It can partially replace ammonium polyphosphate (APP). This odor-free powder is compatible with polyolefins, elastomers, and other thermoplastics, and is suitable for thermoforming and injection molding processes. Melagard MP is ideal for applications requiring flame retardant properties without the use of halogens.

Application Information

Melagard MP is a salt of Melamine and Phosphoric Acid, when it decomposes under high temperature, it undergoes endothermic decomposition thus acting as a heat sink and cooling the combustion source. The released phosphoric acid acts to coat and therefore shield the condensed combustible polymer or surface of the combustible materials. 25-30% Melagard MP is the suggested dosage for Polymer or Intumescent Coatings

Processing Instructions

Melagard MP can be processed up to 250°C on typical polymer processing equipments (single or twin screw extruders, internal batch mixers (Banbury type) and roll mills). Molding operations such as injection molding and composites thermal forming are easily accomplished.
