Melamine Cyanurate (MCA) - Nitrogen-Based Flame Retardant with Lubricating Properties
Product Introduction
Melamine Cyanurate (MCA, Chemical Formula: C6H9N9O3, Molecular Weight: 255.24) is a high-performance nitrogen-based flame retardant that also boasts excellent lubricating capabilities. It appears as white crystalline fine powder or granules, being non-toxic, odorless, and featuring outstanding thermal stability.
Product Description
Physical Properties
- Appearance: Available in two forms — white crystalline fine powder or granules.
- Odor & Toxicity: Non-toxic and odorless.
- Sublimation Temperature: 440°C.
- Density: 1500–1600 kg/m3.
- Water Solubility (20°C): 0.001 g/100ml (extremely low solubility, ensuring stability in aqueous environments).
Key Features
- High Nitrogen Content (≈30%): When added to rubber, plastics (notably effective in nylon with moderate dosage), it delivers prominent flame-retardant performance.
- Superior Thermal Stability: Shows minimal thermal weight loss during long-term heating below 300°C.
- Graphite-Like Layered Structure & Lubricity: Enables excellent electrical and mechanical properties under harsh conditions (high temperature, high pressure, heavy load, and impact load).
- Stable Lubrication Performance: Maintains consistent lubrication characteristics under extreme scenarios (high temperature, high speed, low temperature, low speed, or rapid temperature fluctuations).
Applications
MCA is a multifunctional agent combining flame retardancy and lubrication, widely used in:
- Polymer & Composite Materials: Rubber, nylon, epoxy resin, acrylic emulsion, PTFE resin, and halogen-free flame retardants for plastic products.
- Lubrication Sector: As a solid lubricant additive in lubricating oils and greases; as a flame-retardant and gloss agent in fireproof coatings; and as a lubricant in cosmetics.
- Specialized Fields: Ideal for unfilled nylon 6/66 (flame-retardant products can achieve UL94 V-0 rating at 960℃, 1.6mm); as an anti-rust lubricating film for steel wire drawing and stamping; and as a lubricant for general mechanical transmission parts.
