TF-201S Fine partical size Flame Retardant of ammonium polyphosphate for EVA

TF-201S is commonly used as a flame retardant additive in epoxy adhesives.

Its function is to increase the fire resistance and reduce the flammability of the adhesive.

When TF-201S is heated, it undergoes a process called intumescence, which involves the release of non-combustible gases and the formation of a protective char layer. This char layer acts as a barrier, preventing the heat and flame from reaching the underlying material.

The mechanism of action of TF-201S in epoxy adhesives can be summarized as follows:

1. Phosphorus Content: TF-201S contains phosphorus, which is an effective flame retardant element. Phosphorus compounds interrupt the combustion process by inhibiting the release of flammable gases.

2. Dehydration: As TF-201S decomposes under heat, it releases water molecules. The water molecules are converted into steam due to the heat energy, which helps dilute and cool the flames.
