    Product introduction

    Melamine cyanurate ( MCA ) is a kind of white power. It has excellent electricity performance, especially adaptable to electric equipment and Electronic Industrie Non-toxic and environmental protection.

    Melamine Cyanurate is a halogen-free flame retardant that can be used in thermoplastic urethanes (TPUs) for electrical wire coatings. MCA especially applies to nylon number 6 and number 66, which can achieve the anti-flaming effect with UL 94 V level easily; It's worthwhile to point out that it has such advantages as very low application cost, super electrical capacity, mechanical performance, and excellent pigmentation effect, etc.

    1. Halogen-free, low smoke density, low toxicity, and less corrosion.

    2. High sublimation temperature (440°C) with high thermal resistance and thermal processing stability.

    3. Good economics and mechanical properties, compared to compounds containing halogen/antimony flame retardant systems

    4. Lower corrosion offers advantages in the processing stage or fire hazard.

    5. UL94V-0 rating for unfilled or mineral filled compounds.

    6. UL94V-2 rating for glass filled compounds.


    1. primarily used for nylon.

    2. Primarily for electrical & electronic applications (connectors, switches, etc.) made from polyamide or thermoplastic polyurethane.

    3. Suitable for synthetic resins (i.e. PA, PVC, PS).


    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.

    Properties of Melamine Cyanurate

    Melamine Cyanurate is a salt comprised of Melamine and Cyanuric acid, which has unique physical properties: heat stability at 300º.

    Held together by an extensive two-dimensional network of hydrogen bonds between Melamine and Cyanuric acid, which network forms layers such as graphite.
