JLS-APP |
|
Ammonium polyphosphate (crystalline form ll, n>1000). JLS-APP is a fine-particle ammonium polyphosphate produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is white, non-hygroscopic and non-flammable, whose crystalline form is II, n>1000. JLS-APP may be mostly used in intumescent coating, polyurethane foams and cellulose(for example: paper and wood). Because of its high heat stability, JLS-APP is all essential component in intumescent formulations for thermoplastics, particularly polypropylene, for which the classification UL 94-V0 is specified for application in the electrical sector. |
