The invention relates to a method for producing a free flowing flame retardant material, comprising steps of i. preparing an aqueous slurry from a freshly prepared moist melam having a water content of at least 8 wt. %, relative to the total weight of the moist melam, the slurry comprising water, melam and a water soluble polymeric binding agent, wherein the melam is present in an amount of 5-35 wt. % relative to the total weight of the slurry, and the water soluble polymeric binding agent is present in an amount of 0.5-8 wt. % relative to the total amount of melam and the water soluble polymeric binding agent; ii. drying the slurry in a fluid bed to form a granulate material; and iii. collecting the resulting granulate material. The invention also relates to a melam granulate material, obtainable by said process.
A process for the preparation of a melam granulate material, the process comprising steps of:
