Melamine Cyanurate (MCA)
Chemical name: Melamine Cyanurate
Brand name: GreatBay XZ-MCA
Equivalent grade: Melapur MC25

CAS NO.: 37640-57-6
Physical appearance: fine, white, crystalline powder, nontoxic, odourless ; in dissolvable in water and most organic solvents.
Use: Melamine Cyanurate is a halogen-free flame retardant for polyamide. Melamine Cyanurate has established itself as the flame retardant to achieve UL 94 V-0 especially for polyamide 6 and 6,6. Addition of MCA gives PA6(66) good mechanical and electrical properties. Being halogen free also results in significant advantages in terms of fire safety, i.e. lower smoke density, lower smoke-toxicity and less corrosion.
Quality Standard: The above information is just for reference, customers shall adjust the formulations according to actual requirements.
