HOFNIL-FR 255

(Melamine Cyanurate)

HOFNIL-FR 255 is a halogen-free flame retardant that is highly effective for use in polyamides. It is widely
employed to help materials achieve the stringent UL 94 V-0 flame retardancy rating. This compound is
particularly suitable for enhancing the flame resistance of polyamides, thermoplastic polyurethanes (TPU), and
polybutylene terephthalate (PBT). The combination of melamine and cyanuric acid in this compound provides a
synergistic effect that significantly enhances the Flame retardant properties, making it an essential additive for
various high-performance applications where safety and compliance are critical.
