Established in 1998, Taixing is a manufacturer and supplier of . We can provide melamine cyanurate, a halogen-free flame retardant that promotes char formation and reduces smoke during combustion. It provides highly effective flame retardancy even at low dosages and is highly recommended for industries with high safety standards.
During the heating process, undergoes a strong endothermic decomposition reaction, which carries away a large amount of heat, slowing down the temperature rise of the material. This can be understood as a cooling process.
When the temperature continues to rise, MCA will release non-flammable gases such as ammonia and nitrogen, which dilutes the concentration of oxygen and flammable gases and has an inhibitory effect on the intensity of combustion. Then, the nitrogen-containing structure generated after its decomposition can form a dense and stable carbon layer. The inside and outside of the carbon layer are separated from each other, so oxygen and heat cannot enter, and the combustibles inside will not continue to escape. The dripping of burning liquid droplets can also be controlled, reducing the risk of secondary fires.
The most mature and widely used polymer system for MCA is the PA nylon system. For PA 6 and PA 66, it exhibits good dispersibility and strong migration resistance. During flame retardation, it decomposes to produce inert gases and promotes char formation, achieving a UL94 V-0 rating even at relatively low addition levels.
The second type of polymer system for which we recommend MCA is PBT/PET engineering plastics. Using halogenated flame retardants may lead to material embrittlement; switching to a halogen-free flame retardant system can solve this problem, and it also results in low smoke and low toxicity.
Furthermore, for PP/PE modified flame retardant systems, melamine cyanurate can be used synergistically with other flame retardants to promote a denser expanded char structure, inhibit dripping, and reduce smoke density, resulting in a stronger flame retardant effect.
Epoxy resins and polyurethanes can also utilize this type of flame retardant. Therefore, whether considering the polymer system or the industry itself, MCA has a wide range of applications.
