Applications
🔥
Flame Retardant
When heated, MCA forms a layer of carbon foam to minimize contact between the 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. More cost-effective than 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.
🔩
Electroplating Additive
Improves surface properties of plastics and increases adhesion to metal layers during electroplating, resulting in more durable and uniform metal coatings on plastic parts.
🏗️
Concrete Additive
MCA can be used as a concrete additive to increase the strength of concrete, improve its performance, and extend its service life.
🧴
Cosmetic Covering Agent
Used in sunscreen and shaving cream as a covering agent. Non-irritating to the skin, with good adhesion, making 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 (FAQ)
Q1
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 reaction forms a stable, non-toxic compound with a unique laminar crystal structure. It is widely used across industries as a flame retardant, lubricant, matting agent, and various other additives.
Q2
Is Melamine Cyanurate safe for use in consumer products?
Yes. MCA is non-toxic and environmentally friendly. It contains no harmful halogenated byproducts and is safe for use in consumer products such as cosmetics, including sunscreen and shaving cream. It is non-irritating to the skin and provides a smooth application.
Q3
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 or stopping combustion and reducing toxic fumes. Additionally, its high nitrogen content causes the release of water steam and nitrogen gas at elevated temperatures, which dilutes combustible gases and further enhances flame retardant performance.
Q4
What are the advantages of using MCA as a lubricant compared to MoS₂ and PTFE?
MCA's unique laminar crystal structure provides excellent lubricity, effectively reducing friction and wear in mechanical systems. Compared to traditional lubricants such as molybdenum disulfide (MoS₂) and polytetrafluoroethylene (PTFE), MCA is more cost-effective while delivering comparable or superior performance, making it an attractive choice for high-performance greases in automotive and industrial applications.
Q5
What packaging options are available for Melamine Cyanurate?
MCA is available in various packaging sizes to meet different requirements, including standard 25kg bags, bulk sacks, and custom packaging solutions. Please contact us to discuss specific packaging needs for your application.
Q6
What storage precautions should be followed for Melamine Cyanurate?
MCA should be stored in tightly closed containers in a cool, dry environment. Keep it away from sources of ignition, as dust can form an explosive mixture with air. Take precautionary measures against electrostatic charges — earthing is necessary during loading operations. Always follow general industrial fire protection rules when storing MCA.
