XS-MC Melamine Cyanurate Series

Melamine cyanurate (MCA) is a colorless, odorless and non-toxic white crystalline powder, insoluble in water, soluble in ethanol, formaldehyde and other solvents, weakly acidic. Stable at 300°C, endothermic decomposition at 350°C.

Our company has its own MCA surface modification technology, which solves many application problems such as difficult dispersion and many black and white spots. XS-MC series products are widely used in wire and cable, electronic appliances, building materials, textile coatings and many other fields.
