Basic info

Chemical name: ammonium polyphosphate

Empirical Formula: (NH4PO3)n (n≥1000)

CAS No.: 68333-79-9

Melting point: 275 °C

Relative Density: 1.8 -2.0 g /cm3 ( 25°C )

Application

1. Used to prepare many types of high-efficiency intumescent coatings for the flame proof treatment of multi-story buildings, ships, trains, cables, etc.
2. Used as the main flameproof additive for expanding-type flame retardants used in plastics, resin, rubber, etc.
3. Used in plastics (PP, PE, PVC, etc.), polyester, rubber, expandable fireproof coatings.
4. Flameproof treatment for woods, plywood, fiberboard, papers, and fibers.
5. Can be used for PU applications (thermosets) and PU foam (rigid and/or flexible)

Benefits

1. Halogen and formaldehyde-free, non-toxic and does not generate additional quantities of smoke.
2. Requires lower loadings ensuring lower cost, better properties retention and excellent flow.
3. Exhibits excellent processability, good retention of mechanical and electrical properties in thermoplastic formulations
4. In thermosets, can be used in conjunction with ATH, which allows a significant reduction of the total FR filler

High polymerization degree ("n" value > 1000), higher thermal stability and lower water solubility than APP-I.

Packing

1. 25 kgnet weight woven plastic / polyethylene bags

2. 20 MT per 20 foot container
