With the high molecular phosphate-nitrogen base flame retardant, under the mechanism of intumescence, JLS LSNH Cable compound posses excellent flame retardancy.
² While fire comes, the flame retardant starts to react and decompose into polymeric phosphoric acid and ammonia.
²The polyphosphoric acid reacts with hydroxyl or other groups of a synergist to a non stable phosphate ester. Afterwards, the dehydration of the phosphate ester follows.
²A carbon layer is then formed on the surface against the fire/heat (charring). The carbon barrier acts as an insulation layer, protecting the material and limiting the spread of flame.
