What melamine cyanurate does, and who buys it
HOFNIL-FR 255 is a halogen-free flame retardant that is highly effective in polyamides and widely used to help materials reach UL 94 V-0. It also suits thermoplastic polyurethane (TPU) and PBT.
As general background, melamine cyanurate is a nitrogen-based flame retardant, and nylon is the polymer it is most often used in. Tell us the polymer and the rating you need and we will advise on dosage.
In polyolefins, an intumescent blend such as HOFNIL-FR 264 is often used with MCA or melamine polyphosphate (MPP); it is listed on our standalone flame retardant additives page.
