Basic Information
- Product Name: Melamine Cyanurate (MCA)
- CAS No: 37640-57-6
- Molecular Formula: C?H?N?O?
- Molecular Weight: 255.2
- EINECS: 253-575-7
- Synonyms: 1,3,5-Triazine-2,4,6(1H,3H,5H)-trione compound with 1,3,5-triazine-2,4,6-triamine (1:1); MCA
Physical & Chemical Properties
- Appearance: White crystalline fine powder, odorless, tasteless
- Density: 1.7 g/cm3
- Melting Point: >300 °C (decomposes at 350 °C)
- Boiling Point: 557.5 °C (760 mmHg)
- Solubility: Practically insoluble in water (0.001 g/100 mL); slightly soluble in hot ethanol, formaldehyde
- Stability: Thermally stable up to 300 °C; decomposes endothermically above 350 °C
- pH: Weakly acidic (aqueous dispersion)
Key Features
- Halogen-Free Flame Retardant: High nitrogen content (≥48%); provides excellent flame retardancy (UL 94 V-0) with low smoke and non-toxic gas emission
- Dual Function: Acts as both flame retardant and solid lubricant (graphite-like layered structure)
- High Thermal Stability: Minimal weight loss at 300 °C; suitable for high-temperature processing
- Environmentally Friendly: Non-toxic, non-corrosive, no halogenated byproducts
- Good Dispersion: Easily dispersible in polymers and oil media
Applications
- Plastics & Polymers: Primary flame retardant for PA6/PA66, PET, PBT, TPU, EVA, epoxy resins, and polyolefins
- Rubber Industry: Flame retardant and lubricant for rubber compounds
- Electrical & Electronics: Flame-retardant insulating components (high dielectric strength)
- Lubricants: Solid lubricant additive (replaces molybdenum disulfide in high-load applications)
- Coatings & Adhesives: Flame retardant for intumescent coatings and epoxy adhesives
