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

  1. High Nitrogen Content (≈30%): When added to rubber, plastics (notably effective in nylon with moderate dosage), it delivers prominent flame-retardant performance.
  2. Superior Thermal Stability: Shows minimal thermal weight loss during long-term heating below 300°C.
  3. Graphite-Like Layered Structure & Lubricity: Enables excellent electrical and mechanical properties under harsh conditions (high temperature, high pressure, heavy load, and impact load).
  4. 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.
