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 generates 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. 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 deliver a matte effect. MCA has good adhesion with resin and offers better matting performance than titanium dioxide and silica.
🔩 Electroplating Additive
Used as a plastic additive in electroplating applications, MCA improves surface properties of plastics and increases their adhesion to metal layers, 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
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.

- 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 highly versatile, used across 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 carbon foam layer that minimizes contact between the polymer and oxygen, slowing or stopping burning and reducing toxic fumes. Its high nitrogen content also generates water steam and nitrogen gas at high temperatures, diluting combustible gases and further improving flame retardant performance.
Q Is Melamine Cyanurate safe for use in consumer products?
Yes. MCA is non-toxic and non-halogenated, making it environmentally safe and suitable for use in consumer products such as cosmetics, sunscreen, and shaving cream. It is non-irritating to the skin and does not produce harmful halogenated byproducts.
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 reduces friction and wear in mechanical systems. Compared to traditional molybdenum disulfide (MoS₂) and polytetrafluoroethylene (PTFE), MCA is more cost-effective while delivering comparable or superior performance in high-performance greases and lubricants for automotive and industrial 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 tailored to meet specific customer requirements for shipping, storage, and handling.
Q What precautions should be taken when storing Melamine Cyanurate?
MCA should be stored in tightly closed containers in a cool, dry place away from sources of ignition, as dust can form explosive mixtures with air. Precautionary measures against electrostatic charges — including earthing during loading operations — should be followed, along with general industrial fire protection rules.
