Brief Introduction:
Melamine Cyanurate (MCA) is a halogen-free flame retardant widely used in various polymers and engineering plastics. It is a synergistic compound of melamine and cyanuric acid, offering excellent flame retardancy, thermal stability, and electrical insulation properties. MCA is environmentally friendly, non-toxic, and exhibits low smoke emission during combustion, making it a preferred choice for applications requiring high safety standards.
