Applications
🔥 Flame Retardant: When heated, MCA forms a layer of carbon foam to minimize the contact between the polymer and oxygen, thus slowing down or stopping burning and reducing the toxic fumes produced by the burning. It has a high nitrogen content, and water steam and nitrogen gas will be produced at high temperature, which can reduce the concentration of combustible gas and improve the flame retardant performance.
⚙️ Lubricant: MCA's unique laminar crystal structure provides excellent lubricity, reducing friction and wear in mechanical systems. It's more cost-effective than traditional molybdenum disulfide (MoS2) and polytetrafluoroethylene (PTFE). It is commonly used for high-performance greases and lubricants in automotive and industrial applications.
🎨 Matting Agent: As a matting agent, MCA is used in coatings to reduce gloss and give a matte effect. It has good adhesion with resin and better matting performance than titanium dioxide and silica.
🔩 Electroplating Additive: Melamine cyanurate is used as a plastic additive in electroplating applications. It improves the surface properties of plastics and increases their adhesion to metal layers during electroplating, making the metal coating on the plastic parts more durable and uniform.
🏗️ Concrete Additive: MCA can be used as a concrete additive to increase the strength of concrete, improve its performance and extend its life.
🧴 Cosmetic Covering Agent: MCA can be used as a covering agent in sunscreen and shaving cream. It is non-irritating to the skin, has good adhesion, and makes the product smoother.

Frequently Asked Questions
Q
What is Melamine Cyanurate (MCA) and how is it produced?
Melamine Cyanurate (MCA) is a white crystalline powder produced by combining melamine and cyanuric acid. The resulting compound is stable, non-toxic, and features a unique laminar crystal structure that makes it useful across a wide range of industrial and consumer applications.
Q
How does Melamine Cyanurate work as a flame retardant?
When heated, MCA forms a protective carbon foam layer that limits contact between the polymer and oxygen, slowing or stopping combustion. At high temperatures, it also releases water steam and nitrogen gas, which dilute combustible gases and further enhance flame retardant performance.
Q
Is Melamine Cyanurate safe for use in consumer and cosmetic products?
Yes. MCA is non-toxic and non-irritating to the skin. It is approved for use as a covering agent in consumer products such as sunscreen and shaving cream, providing good adhesion and a smooth texture without harmful side effects.
Q
What are the advantages of using MCA as a lubricant compared to MoS2 and PTFE?
MCA's laminar crystal structure provides excellent lubricity similar to molybdenum disulfide (MoS2) and polytetrafluoroethylene (PTFE), but at a significantly lower cost. This makes it a more economical choice for high-performance greases and lubricants in automotive and industrial applications.
Q
What packaging options are available for Melamine Cyanurate?
MCA is available in various packaging formats including 25kg bags, bulk sacks, and customized packaging solutions tailored to meet specific customer or logistics requirements.
Q
What precautions should be taken when storing Melamine Cyanurate?
MCA should be stored in tightly closed containers in a cool, dry place away from all sources of ignition. Precautionary measures against electrostatic charges are required during loading operations, and general industrial fire protection rules must be followed, as MCA dust can form an explosive mixture with air.
