The increasing demand for safer and more environmentally sustainable materials has placed a spotlight on flame retardants. Halogenated flame retardants, while effective, often come with significant environmental and health concerns. This has led to a surge in the adoption of halogen-free alternatives, with Melamine Cyanurate (MCA) emerging as a leading solution. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing high-quality MCA, enabling our clients to achieve superior fire safety in their polymer products.

The Need for Halogen-Free Flame Retardants

Traditional flame retardants often contain halogens, such as bromine or chlorine. When these chemicals decompose during a fire, they can release toxic and corrosive gases, posing risks to human health and the environment. Regulatory bodies worldwide are increasingly restricting the use of certain halogenated flame retardants, pushing industries to seek safer alternatives. MCA, being halogen-free, offers a compelling solution that meets these evolving demands.

How MCA Works in Polymers

Melamine Cyanurate (CAS 37640-57-6) functions primarily as a gas-phase flame retardant. Its efficacy is rooted in its thermal decomposition process, which begins around 320°C. Upon heating, MCA breaks down into melamine and cyanuric acid. These compounds then decompose further, releasing non-combustible gases like ammonia and nitrogen. These gases dilute the concentration of oxygen and flammable pyrolysis products in the vicinity of the flame, effectively quenching it. Simultaneously, the decomposition can promote the formation of a stable char layer on the polymer surface. This char acts as a barrier, insulating the underlying material from heat and oxygen, and reducing the release of flammable gases. This two-pronged mechanism significantly enhances the flame retardancy of polymers.

MCA in Key Polymer Applications

Our Melamine Cyanurate is widely utilized in various polymer systems to improve their fire performance:

  • Polyamides (PA6, PA66): MCA is an excellent flame retardant for polyamides, enabling them to meet stringent fire safety standards like UL94 V-0, often with as little as 8% addition. It contributes to reduced smoke generation and lower corrosivity compared to halogenated alternatives. If you are looking to buy Melamine Cyanurate for polyamide applications, our product delivers consistent performance.
  • Polypropylene (PP) and Polybutylene Terephthalate (PBT): These engineering plastics also benefit significantly from the addition of MCA. It provides effective flame retardation without compromising the desirable mechanical and thermal properties of PP and PBT, making them suitable for demanding applications in automotive and electronics.
  • Other Polymers: MCA is also effective in other polymers such as thermoplastic polyurethanes (TPUs), epoxy resins, and polystyrene, offering a versatile solution for a broad range of plastic formulations.
