Key properties:
GD-APP101 is a fine-particle
ammonium polyphosphate produced
by a special method.The pruduct
is largely insoluble in water and
completely insoluble in organic
solvent. It is white, non-
hygroscopic and non-
flammable,whose crystalline form
is II,n>1000.
1,Low water solubility GD-APP101
has low water solubility which
makes it useful in application
where the product is exposed to
high humidity conditions or water.
2,High phosphorus content GD-
APP101 contains 72.5% phosphorus
(as P2O5) which makes it a very
effective fire retardant.
3,Nearly neutral PH-GD-APP101 can
be neutralized or brought to the
alkaline side by the addition of
small amounts od ammonium
hydroxide.
4,Non-halogen-GD-APP101 is a
highly effective non-halogen fire
retardant.
Applications:
1,GD-APP101 can be used in
intumescent coatings,paints.
2,GD-APP101 can be used in
adhensive and sealants
3,GD-APP101 can be used in
polyurethane foam: PU rigid, PU
rigid integral skin foam, PU
flexible.
4,GD-APP101 can be used in
cellulose-containing material
(paper, wood ).
5,GD-APP101 can be usd in
thermoplastics (PP)
6,GD-APP101 can be used in
casting resin based on epoxy
resin and unsaturated PE resin
