Melamine Cyanurate (MCA), with its chemical formula C6H9N9O3 and CAS number 37640-57-6, is a crystalline solid renowned for its effectiveness as a halogen-free flame retardant. As a salt formed from melamine and cyanuric acid, it possesses a unique thermal stability, remaining stable up to approximately 320°C before undergoing endothermic decomposition. This property makes it particularly suitable for polymers that require higher processing temperatures, such as polyamides (PA6, PA66), TPUs, and other engineering plastics.

The manufacturing process for MCA typically involves an aqueous phase salt formation reaction between melamine and cyanuric acid. This process, when conducted under controlled conditions, yields a product with high purity, often exceeding 99.5% MCA content, with minimal levels of residual melamine or cyanuric acid. For end-users, particularly those in the plastics industry, sourcing MCA in compacted pellet form is a significant advantage. This physical state simplifies handling, storage, and precise dosing into processing equipment, contributing to consistent flame retardant performance in the final product. As a dedicated manufacturer, we focus on delivering this user-friendly pelletized format.

The flame retardant mechanism of MCA is primarily based on its decomposition into inert gases. When exposed to fire, it releases ammonia and nitrogen, which dilute oxygen and flammable gases, effectively smothering the flame. Additionally, the decomposition process can promote the formation of a char layer, which acts as a thermal barrier, further protecting the polymer. This makes it a powerful tool for achieving critical flammability ratings like UL94 V-0.
