 |
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. |
