Basic
info
Chemical name: ammonium
polyphosphate
Empirical Formula: (NH4PO3)n
(n≥***0)
CAS No.:
*******9
Melting point: **5 °C
Relative Density: 1.8 2.0 g /cm3 (
*5°C )
Application
1.
Used to prepare many types of
highefficiency intumescent coatings for the flame proof
treatment of multistory buildings, ships, trains, cables,
etc.
2. Used as the main flameproof
additive for expandingtype 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 formaldehydefree,
nontoxic 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
5. High polymerization degree ("n"
value > ***0), higher thermal stability and lower water
solubility than APPI.
