Nitrogen

Mode of action: Nitrogen-containing flame retardants may act by the release of inert gases (ammonia, nitrogen) into the gas phase or by condensation reactions in the solid phase.


Important nitrogen-containing flame retardants are:

Melamine is mainly used for flame retarding polyurethane flexible foams for upholstered furniture in homes (UK and Ireland), as well as in railway and aircraft seats.


Melamine cyanurate (MC) is used in reinforced polyamide 6 and 66.


Melamine polyphosphate (MPP) is used in glass fiber reinforced polyamide 6 and 66. Together with metal phosphinates it shows a synergistic effect.


Melamine poly(zinc- or aluminum)phosphates have a synergistic effect with metal phosphinates in polyamides and polybutylene terephthalate, as well as with aluminum and megnesium hydroxide in cable applications.


Melamine-based HALS (Hindered Amine Light Stabilizer) is used in polyolefin films. The mode of action is based on the enhanced degradation of the polyolefin by radicals, which may also act in the gas phase.
