Melamine Cyanurate MC

Good prospects seem likely to be fulfilled for melamine cyanurate (MC), which has appeared like a material-in-waiting, with a global consumption of around 15,000 toimes. Development in Europe advanced quicker than elsewhere, mainly due to the presenee of the raw materials in the region, with the major outlet being for polyurethane foam. The expiry of a Japanese patent for MC in polyamides should have an impact, but the most relevant development has been suitable compounding techniques.

Melamine cyanurate, Melapur MC, is less successful in glass filled polyamide compounds than Melapur 200, but works well in uiu-einforced PA66 or a mineral-filled formulation, achieving V-0 at 6-10% loading for the former, and at 13-15% in the latter. 

Melamine cyanurate is another candidate for utilisation in polyamide compounds but it is restricted to unreinforced polyamides due to its limited thermal stability. A loading of 12% can give V-0 rating for UL94. There is also the possibility of some plate-out or blooming with MC. 

Melamine cyanurate powder, containing nearly 50% of nitrogen can be used as an additive to polyamide 6 at the melt stage before fibre spinning or plastics production. The addition of MC lowers the specific tenacity of the fibres but decreases the flammability. This latter effect is stronger in solid plastics than for fibres.
