Melamine Cyanurate: An Excellent Environmentally Friendly Flame Retardant

As commonly used high-performance materials, nylon 6 and nylon 66 have good mechanical properties, but their flammability limits their application in scenarios with high fire protection requirements. The emergence of melamine cyanurate (MAC) has brought a breakthrough in the flame retardant modification of nylon materials. Melamine cyanurate is added to nylon 6 and nylon 66. During the heating process, melamine cyanurate works synergistically through the dual mechanisms of condensed phase and gas phase flame retardancy. In the gas phase, melamine cyanurate decomposes to produce non-flammable gases such as ammonia and nitrogen, forming a barrier layer on the surface of the material to dilute the concentration of combustible gases and oxygen; in the condensed phase, its decomposition products cause the material surface to form a dense carbonized layer, hindering heat transfer and contact with oxygen, thereby achieving efficient flame retardancy. Finally, nylon materials with an appropriate amount of melamine cyanurate added can meet the stringent UL94 V-0 flame retardant standard, giving the material fire resistance. The addition of melamine cyanurate has little effect on the mechanical properties of nylon materials, ensuring that the products can maintain good tensile strength, toughness and other mechanical properties while meeting the flame retardant requirements, meet the mechanical requirements of actual use scenarios, and make the modified nylon materials widely used in automotive parts, electronic and electrical housings and other fields with high requirements for flame retardancy and mechanical properties. ​
Fire Guardian in the Rubber Products Industry​
In the rubber products industry, wires and cables are key carriers of power transmission and signal transmission, and their safety is of vital importance. Traditional rubber materials are flammable, and once a fire occurs, it is very easy to cause the spread of fire and electrical failure. Melamine cyanurate has become an ideal choice for flame retardant treatment of wire and cable sheaths due to its properties. When wires and cables are in abnormally high temperatures or fire environments, melamine cyanurate can quickly play a flame retardant role, effectively inhibit the combustion of rubber sheaths, prevent flames from spreading along cables, and reduce the risk of electrical fires. The low toxicity and environmentally friendly characteristics of melamine cyanurate ensure that no secondary pollutants such as toxic and harmful hydrogen halide gases will be produced when a fire occurs, ensuring personnel safety and environmental health. This reliable flame retardant protection makes wires and cables with melamine cyanurate widely used in many fields such as construction, transportation, and industrial production, building a solid defense line for the safe transmission of electricity and signals. ​
Safety guarantee in the field of construction engineering​
In the field of construction engineering, fire safety has always been a top priority. Melamine cyanurate plays a key role in the manufacture of fire retardant coatings and thermal insulation wallboards. The application of melamine cyanurate to fire retardant coatings can significantly improve the flame retardant properties of coatings. When encountering a fire, the surface of building components coated with melamine cyanurate fire retardant coatings will quickly start the flame retardant mechanism, form a thermal insulation protective layer, delay the deformation and burning speed of components due to heat, and buy precious time for personnel evacuation and fire fighting. In the production of thermal insulation wallboards, the addition of melamine cyanurate not only enhances the flame retardant ability of the wallboard, making it have good fire resistance, but also helps to improve the thermal insulation effect of the wallboard and optimize the energy efficiency of the building. These fire-retardant coatings and thermal insulation wall panels made from melamine cyanurate are widely used in various construction projects, from high-rise residential buildings to large commercial buildings and industrial plants, effectively improving the overall fire safety performance of buildings and protecting people's lives and property in all aspects. Melamine cyanurate plays an irreplaceable role in many fields such as engineering plastics, rubber products, and construction projects due to its flame retardant properties and environmental protection characteristics.
