Use: Melamine Cyanurate is a halogen-free flame retardant for polyamide.
Melamine Cyanurate can be 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.
Package: 20kgs woven bags, PE in liner.
Storage and transportation: Handle with care, keep airtight and dry.
