1. What is Melamine Cyanurate Flame Retardant?

Melamine Cyanurate (MCA) is a nitrogen-based flame retardant composed of melamine and cyanuric acid. It is widely used in polymers, plastics, and textiles to inhibit combustion by releasing nitrogen gases and forming a protective char layer. MCA is non-toxic, halogen-free, and ideal for eco-sensitive applications.

2. How Does Melamine Cyanurate Work?

When exposed to heat, Melamine Cyanurate decomposes and releases nitrogen gas, which dilutes flammable gases and oxygen. Simultaneously, it forms a stable char layer that shields the material from further burning. This dual-action mechanism makes MCA highly effective in suppressing flames.

3. Is Melamine Cyanurate Safe for the Environment?

Yes! Melamine Cyanurate contains no halogens, heavy metals, or harmful additives. At HUNAN MEILAIPO, our MCA products are certified for environmental protection and comply with global standards like RoHS and REACH. It’s a sustainable choice for industries prioritizing eco-friendliness.

4. What Materials Can MCA Be Used In?

MCA is compatible with:

  • Polyamides (nylon 6, nylon 66)
  • Thermoplastics (PP, PE)
  • Textiles and coatings
    Its versatility makes it a top choice for automotive, electronics, and construction industries.

5. How Does MCA Compare to Halogen-Based Flame Retardants?

Feature Melamine Cyanurate Halogen-Based Retardants
Toxicity Non-toxic Often toxic
Environmental Impact Eco-friendly Harmful
Regulatory Compliance Globally accepted Restricted in many regions

MCA outperforms halogen-based options in safety and sustainability.
