Applications
Flame Retardant
MCA forms a layer of carbon foam when heated, minimizing contact between polymer and oxygen, slowing or stopping burning and reducing toxic fumes. Its high nitrogen content releases water steam and nitrogen gas at high temperatures, reducing combustible gas concentration.
Lubricant
MCA's unique laminar crystal structure provides excellent lubricity, reducing friction and wear in mechanical systems. More cost-effective than traditional MoS₂ and PTFE. Commonly used in high-performance greases and lubricants for automotive and industrial applications.
Matting Agent
Used in coatings to reduce gloss and deliver a matte effect. MCA has good adhesion with resin and better matting performance than titanium dioxide and silica.
Plastic Additive for Electroplating
MCA improves the surface properties of plastics and increases their adhesion to metal layers during electroplating, making metal coatings on 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 service life.
Cosmetics & Personal Care
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
- Avoid dust formation
- Follow the usual precautions for handling chemicals
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 produced by the chemical combination of melamine and cyanuric acid. The resulting compound is stable, non-toxic, and exhibits multifunctional properties, making it suitable for use as a flame retardant, lubricant, matting agent, and various other additives across multiple industries.
Q
How does MCA work as a flame retardant?
When heated, MCA forms a protective layer of carbon foam that minimizes contact between the polymer and oxygen, thereby slowing down or stopping combustion and reducing toxic fumes. Additionally, MCA's high nitrogen content generates water steam and nitrogen gas at elevated temperatures, which dilutes combustible gases and further enhances flame retardant performance.
Q
Is Melamine Cyanurate safe for use in consumer products?
Yes. MCA is non-toxic and environmentally friendly. It contains no harmful halogenated compounds that could pollute the environment or damage the ozone layer. It is considered safe for use in consumer products including cosmetics, sunscreen, and shaving cream, where it acts as a non-irritating covering agent.
Q
What are the advantages of MCA as a lubricant compared to MoS₂ and PTFE?
MCA's unique laminar crystal structure provides excellent lubricity that effectively reduces friction and wear in mechanical systems. Compared to traditional lubricants such as molybdenum disulfide (MoS₂) and polytetrafluoroethylene (PTFE), MCA is significantly more cost-effective while delivering comparable or superior performance in high-performance greases for automotive and industrial applications.
Q
Can MCA affect the color of plastic products?
No. One of the key advantages of Melamine Cyanurate is that it never changes the color of plastic products. This makes it particularly valuable in applications where maintaining the original appearance and aesthetics of the plastic material is important.
Q
What packaging options are available for Melamine Cyanurate?
Melamine Cyanurate is available in a variety of packaging sizes to suit different needs, including standard 25kg bags, bulk sacks, and custom packaging solutions.
