application:
Disintegrating agents commonly used in the pharmaceutical industry are insoluble PVPP, hydroxymethyl starch and L-hydroxypropyl cellulose. The decomposition effect of insoluble PVPP tablets is the most obvious and convenient. Because the swelling of insoluble PVPP is reversible, it is not affected by pre-wetting and drying, and its effect and decomposition time are not affected;
can also be used as disintegrant and filler for pills, granules, hard capsules.
storage method:
should be sealed and stored in a clean and dry warehouse, and attention should be paid to fire prevention, waterproof, sun protection, dust prevention and pollution prevention.
higher solid content, higher melt viscosity and better particle distribution.

Diammonium phosphate

OPAP offers purchase service to importers and exporters of Diammonium phosphate from Oman and Dubai ports.
Diammonium phosphate (DAP) (chemical formula (NH4)2HPO4, IUPAC name diammonium hydrogen phosphate) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation:[2]

(NH4)2HPO4(s) NH3(g) + NH4H2PO4(s)
log PmmHg = 3063 / T + 175 log T + 3.3
where:

P = the resultant dissociation pressure of ammonia
T = absolute temperature (K)
At 100 C, the dissociation pressure of diammonium phosphate is approximately 5 mmHg.[3]

Accordingly, to MSDS of DiammoniumPhosphate from CF Industries inc. decomposition starts as low as 70*C

"Hazardous Decomposition Products: Gradually loses ammonia when exposed to air at room temperature. Decomposes to ammonia and monoammonium phosphate at around 70�°C (158�°F). At 155�°C (311�°F), DAP emits phosphorus oxides, nitrogen oxides and ammonia."

Uses
DAP is used as a fertilizer.[4] When applied as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium. It is incompatible with alkaline chemicals because its ammonium ion is more likely to convert to ammonia in a high-pH environment. The average pH in solution is 7.5â??8.[5] The typical formulation is 18-46-0 (18% N, 46% P2O5, 0% K2O).[5]

DAP can be used as a fire retardant. It lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char.[6] These are important effects in fighting wildfires as lowering the pyrolysis temperature and increasing the amount of char formed reduces that amount of available fuel and can lead to the formation of a firebreak. It is the largest component of some popular commercial firefighting products.[7]

DAP is also used as a yeast nutrient in winemaking and mead-making; as an additive in some brands of cigarettes purportedly as a nicotine enhancer; to prevent afterglow in matches, in purifying sugar; as a flux for soldering tin, copper, zinc and brass; and to control precipitation of alkali-soluble and acid-insoluble colloidal dyes on wool.[1]
