Chemical Name: Melamine Cyanurate (MCA)
Formula:C6H9N9O3
Molecular Weight: 255.2
CAS NO.: 37640-57-6
Applications:
Melamine Cyanurate is a halogen-free flame retardant for polyamide. Steadable colour, good electrical property and environmentally friendly, 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.
