Melamine Cyanurate

Applications

  • primarily used for nylon
  • primarily for electrical & electronic applications (connectors, switches, etc.) made from polyamide or thermoplastic polyurethane
  • suitable for synthetic resins (i.e. PA, PVC, PS)

Benefits

  • Halogen-free, low smoke density, low toxicity, and less corrosion
  • High sublimation temperature (440°C) with high thermal resistance and thermal processing stability
  • Good economics and mechanical properties, compared to compounds containing halogen/antimony flame retardant systems
  • Lower corrosion offers advantages in the processing stage or fire hazard
  • UL94V-0 rating for unfilled or mineral filled compounds
  • UL94V-2 rating for glass filled compounds

Packing

  • 20 kg per multi-ply paper bag (10-11 MTs per 20 foot container or 20-22 MTs per 40 foot container)
  • 25 kg per composite woven bag with inner PE lining
  • 600 kg per jumbo bag available upon request
