Why use melamine based FR ?
Melamine based flame retardants represent a small but fast growing
segment in the flame retardant market. These products offer particular advantages
over existing flame retardants:
- Cost effectiveness
- Low smoke density and toxicity
- Low corrosion
- Safe handling
- Environmental friendliness
In this Flame Retardants Center, we offer you:
In this family of non-halogenated flame retardants, three chemical groups can be
distinguished; pure melamine, melamine derivatives, i.e. salts with organic or inorganic
acids such as boric acid, cyanuric acid, phosphoric acid or pyro/poly-phosphoric
acid, and melamine homologues such as melam, melem and melon. The latter finding
only experimental use at this stage.
Melamine based flame retardants show
excellent flame retardant properties
and
versatility in use because of their ability to employ
various
modes of flame retardant action.

Currently, main areas of application for melamine based flame retardants are
flexible polyurethane foams, intumescent coatings,
polyamides and thermoplastic polyurethanes. Through
continued research and application development work, the market for melamine based
flame retardants will further expand in the near future, f.i. in the direction of
polyolefins and thermoplastic polyesters.
