Melamine Formaldehyde Resin Modified Ammonium Polyphosphate For PU/Silicone /Acrylic Coatings
APP(ammonium polyphosphate) is mainly polymerized from monomeric diphosphorus pentaoxide(P2O5) and diammonium hydrogenorthophosphate(DAP)
APP is flame retardant using expansion mechanism.
APP decomposes ammonia gas and polyphosphoric acid at 275 ℃. Ammonia dilutes the oxygen concentration and at the same time expands and loosens the carbon layer to isolate heat.
APP is halogen free, environmental friendly.
Molecular formula : (NH4PO3)n n>1000
CAS No.: 68333-79-9
EINECS No.: 269-789-9
HS CODE: 2835.3990
Model No.: TF-MF201
Product description: Melamine formaldehyde resin modified APP-II is a flame retardant based on phosphorus /nitrogen synergism .
TF-MF201, is different from normal APP II in the following properties:
-Good thermostability
-Better water resistant
-Good fluidity and low solubility, better compatibility with resin
