Melamine Cyanurate (MCA) Formula:C6H9N9O3 Molecular Weight: 255.2 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. Feature: 1.steady colour; 2.good electrical property; 3.environmentally friendly. Pakage: 20kg woven bags, PE in liner. Capacity: 4000T/a Storage and transportation: Handle with care, keep airtight and dry. Quality Standard.
