Applications
🔥 Flame Retardant
Melamine Cyanurate (MCA) forms a layer of carbon foam when heated, minimizing 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 temperature, reducing combustible gas concentration.
⚙️ Lubricant
MCA's unique laminar crystal structure provides excellent lubricity, reducing friction and wear. It is more cost-effective than traditional MoS₂ and PTFE, and is widely used in high-performance greases and lubricants for automotive and industrial applications.
🎨 Matting Agent
Used in coatings to reduce gloss and provide a matte effect. MCA has good adhesion with resin and delivers better matting performance than titanium dioxide and silica.
🔩 Electroplating Additive
Improves the surface properties of plastics and increases 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.
🧴 Cosmetic Covering Agent
Used in sunscreen and shaving cream as a covering agent. 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 synthesized by combining melamine and cyanuric acid. The resulting compound is stable, non-toxic, and widely used across multiple industries including flame retardancy, lubrication, coatings, and cosmetics.
-
Q How does MCA work as a flame retardant?When heated, MCA forms a carbon foam layer that acts as a barrier between the polymer and oxygen, slowing or stopping combustion. Additionally, its high nitrogen content releases water steam and nitrogen gas at elevated temperatures, diluting combustible gases and further enhancing flame retardant performance.
-
Q Is Melamine Cyanurate safe and environmentally friendly?Yes. MCA is non-halogenated and non-toxic, meaning it does not produce harmful halogenated byproducts that pollute the environment or destroy the ozone layer. It is safe for use in consumer products such as cosmetics and is considered an environmentally responsible alternative to halogenated flame retardants.
-
Q What are the main applications of MCA?MCA is used as a flame retardant in plastics, a lubricant in automotive and industrial greases, a matting agent in coatings, a plastic additive in electroplating, a concrete strength additive, and a covering agent in cosmetics 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 cost-effective alternative for high-performance greases and lubricants in demanding industrial and automotive applications.
-
Q What packaging options are available for MCA?MCA is available in various packaging sizes including 25kg bags, bulk sacks, and other custom packaging solutions designed to meet specific customer requirements and logistics needs.
