Applications
🔥 Flame Retardant
Melamine Cyanurate (MCA) forms a layer of carbon foam when heated to minimize contact between the polymer and oxygen, slowing or stopping burning and reducing toxic fumes. Its high nitrogen content produces water steam and nitrogen gas at high temperatures, reducing combustible gas concentration and improving flame retardant performance.
⚙️ 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 for high-performance greases and lubricants in automotive and industrial applications.
🎨 Matting Agent
Used in coatings to reduce gloss and deliver a matte effect. Offers good adhesion with resin and better matting performance than titanium dioxide and silica.
🔩 Electroplating Additive
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
Used as a concrete additive to increase strength, improve performance, and extend the service life of concrete structures.
🧴 Cosmetics / Personal Care
Used as a covering agent in sunscreen and shaving cream. Non-irritating to the skin, with good adhesion, making products 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 made?
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 MCA 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 and reducing toxic fumes. Additionally, its high nitrogen content generates water steam and nitrogen gas at elevated temperatures, diluting combustible gases and further enhancing flame retardant performance.
Q Is Melamine Cyanurate environmentally friendly and safe?
Yes. MCA is non-halogenated, meaning it does not produce harmful halogenated byproducts that pollute the environment or damage the ozone layer. It is also non-toxic, making it safe for use in consumer products such as cosmetics and personal care items.
Q What are the main industries and applications for MCA?
MCA is used across a wide range of industries including plastics (as a flame retardant), automotive and industrial sectors (as a lubricant), coatings (as a matting agent), electroplating (as a plastic surface additive), construction (as a concrete strength enhancer), and personal care (as a covering agent in sunscreen and shaving cream).
Q How does MCA compare to traditional lubricants like MoS₂ and PTFE?
MCA offers comparable lubricity to traditional lubricants such as molybdenum disulfide (MoS₂) and polytetrafluoroethylene (PTFE) due to its unique laminar crystal structure. However, MCA is significantly more cost-effective, making it a preferred choice 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 formats including standard 25kg bags, bulk sacks, and customized packaging solutions designed to meet specific customer requirements and logistics needs.
