Powder&Granule
Formula:C6H9N9O3
Molecular Weight:255.24
Melamine Cyanurate is a white crystal power with satiny. It is a excellent non-halogen N flame retardant.The product is mainly used as non-halogen flame retardant for synthetic resin(PA,PVC,PS,POM),synthetic rubber and plastic products;solid lubricant in lubricating oil and grease;fire retardant in fire-proofing coating;lubricant in lubricating oil and grease;fire retardant in fire-proofing coating;lubricant in the cosmetic.MCA is used specifically for PA6 and PA66 without packing,and the materials that are treated with it shall have a excellent flame resistance to UL 94V-0(960℃,1.6mm).
The MCA Granule exhibits main advantages as below:
1. Pellet appearance and smart packing which will make both the transportation and depositing with ease.
2. Good fluidity and dispersancy in process.
3. Reduced loss and pollution to environment by MCA masterbatch in comparision with by MCA powder.

(3) The product advantages
Ⅰ. MCA is an excellent flame retardant,non-poison and non-corrosion.
Ⅱ. With sublimation temperature 440℃,MCA has a high thermal resistance and a good thermostability in the processing.
Ⅲ. Using the product may costless,and get good electrical and mechanical properties.
Ⅳ. The synthetic resin added with MCA has excellent qualities:the resin will not fade and not have exudates of MCA in the surface.

C.Excellent results of using the compound of MCA and other flame retardants
The compound of MCA and red phosphorus(P:3-6%，MCA 10-15)
The compound of MCA and Sb2O3(Sb2O3:2-5%,MCA 8-15)
Both of them will have excellent flame resistance to UL 94V-0,with OI 38.0.
