TF-251 is a non-halogenated flame retardant based on phosphorus and nitrogen synergism. The product achieves its flame retardant effect through intumescence. The thermoplastic material foams and crosslinks on exposure to flame and forms a stable char at the surface acting as barrier.
The protective layer provides a heat-insulation effect , reduces oxygen access and provents dripping of molten polymer.
The density of final product with TF-251 is low and low smoke will be produced when burning . Problems such as hydration and salinification will not emerge.
