Related Product Features:
  • Halogen-free and environmentally friendly flame retardant with high nitrogen content for effective fire suppression.
  • Decomposes at high temperatures to release nitrogen, water, and carbon dioxide, absorbing heat to achieve flame retardancy.
  • Excellent thermal stability with decomposition temperatures exceeding 300°C, suitable for most resin processing.
  • Low toxicity and no environmental hazards, making it a safe alternative to brominated compounds.
  • Widely used in polyamides, polyurethanes, polyesters, epoxy resins, and engineering plastics.
  • Also applicable in textiles, paints, coatings, and construction materials like foam insulation.
  • Acts as a curing agent for epoxies and reduces smoke emission during fires.
  • Economical and easy to manufacture, ideal for large-scale industrial applications.
FAQs:
  • What is Melamine Cyanurate (MCA) used for?
    MCA is primarily used as a halogen-free flame retardant in plastics like polyamides, polyurethanes, polyesters, and epoxy resins, as well as in textiles, paints, coatings, and construction materials to enhance fire resistance.
  • How does MCA achieve flame retardancy?
    MCA works through sublimation heat absorption and high-temperature decomposition, releasing gases like nitrogen, water, and carbon dioxide that carry away heat, thereby suppressing flames and reducing fire spread.
  • Is MCA safe for the environment?
    Yes, MCA is halogen-free, has low toxicity, and poses no environmental hazards, making it a safer alternative to traditional brominated flame retardants.
  • What are the key specifications of MCA?
    Key specifications include ≥99.5% MCA content, ≥49% nitrogen, decomposition temperatures above 300°C, particle size D50 ≤6µm and D97≤30µm, and a pH of 5.0-7.5 in aqueous suspension.
