Melamine Cyanurate (MCA)

1.Name:Melamine Cyanurate (MCA) 2.CAS NO.:37640-57-6 3.MCA:99.5%

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.

Feature: 1.steady colour;2.good electrical property;3.environmentally friendly
