Applications
Flame Retardant
Melamine Cyanurate (MCA) is widely used as a 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 can be used as a lubricant, and its 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. This makes 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.
Handling and Storage
Handling

Storage
- Follow the general rules of industrial fire protection
- Take precautionary measures against electrostatic charges — earthing necessary during loading operations
- Keep away from sources of ignition, because dust can form an explosive mixture with air
- Keep containers tightly closed, cool and dry
Packaging
Available in various packaging sizes, such as 25kg bags, bulk sacks, and other custom packaging solutions to meet specific requirements.
Frequently Asked Questions
Q What is Melamine Cyanurate (MCA) and how is it produced?
Melamine Cyanurate (MCA) is a white crystalline powder synthesized by combining melamine and cyanuric acid. The resulting compound is stable, non-toxic, and widely used across multiple industries as a flame retardant, lubricant, matting agent, and various other additives.
Q How does Melamine Cyanurate work as a flame retardant?
When heated, MCA forms a protective layer of carbon foam that minimizes contact between the polymer and oxygen, slowing or stopping combustion. Additionally, its high nitrogen content causes the release of water steam and nitrogen gas at elevated temperatures, reducing the concentration of combustible gases and enhancing flame retardant performance.
Q Is Melamine Cyanurate environmentally friendly?
Yes. MCA is a non-halogenated flame retardant, meaning it does not produce harmful halogenated byproducts that pollute the environment or destroy the ozone layer. It is also non-toxic, making it safe for use in consumer products such as cosmetics.
Q What are the main applications of Melamine Cyanurate?
MCA is used in a wide range of applications including: flame retardants for polymers and plastics, lubricants for automotive and industrial systems, matting agents in coatings, plastic additives for electroplating, concrete additives to improve strength and durability, and covering agents in cosmetic products such as sunscreen and shaving cream.
Q How does MCA compare to traditional lubricants like MoS2 and PTFE?
MCA's unique laminar crystal structure provides excellent lubricity comparable to molybdenum disulfide (MoS2) and polytetrafluoroethylene (PTFE), but at a significantly lower cost. This makes it a highly cost-effective alternative for high-performance greases and lubricants in both automotive and industrial applications.
Q What packaging options are available for Melamine Cyanurate?
MCA is available in various packaging sizes including 25kg bags, bulk sacks, and custom packaging solutions tailored to meet specific customer requirements. Please contact us for more information on available packaging options.
