MC-series are

eco-friendly non-halogen flame retardants that have exceptional resistance to heat (>300 ℃) and water, whose properties lead to almost unlimited application to various resins.

They are characterized by excellent flame retardation when they are used in such nitrogen-containing resins as polyamides and polyurethanes; and they can highly increase flame-retardation capability when they are used with phosphorous-based or inorganic flame retardants.

▶▶  Structural formula of Melamine Cyanurate
  • Display excellent resistance to heat (>300℃) and discoloration.
  • Have good waterproofness and moisture resistance
    (little or no chances of absorbing moisture even during the rainy season).
  • Exhibit exceptional flame retardation in resins that contain nitrogen such as nylon polymers (polyamides) and urethanes.
  • Produce good flame retardation in thermosetting resins such as epoxy and UPRs.
  • Are suitable for applications that require good electric properties.
  • Especially, MC-130P contains an extremely low amount of impurity and thus is ideal for application to electronic parts.
  • MS-1020 is a water-soluble slurry of very fine particles that does not cause any precipitation problems, whose property enables easy application to EPS (expanded polystyrene) and non-woven fabrics when they are mixed with water-based adhesives.
