Nano-Dispersible Dry Powder
Colloidal Antimony Pentoxide Flame Retardant Additives
BurnEx™ A1582, BurnEx™ ADP480, BurnEx™
ADP494
Nyacol Nano Technologies, Inc.
offers nano-dispersible dry powder colloidal antimony pentoxide for use
as synergists with halogenated flame retardants in polymers, solvents and
adhesives.
Advantages
over a conventional antimony trioxide system:
· Low
chemical reactivity that will not interfere with electroless plating
solutions
· Free-flowing
particles for exceptional consistency, better mixing and easy processing
· Non-pigmenting
for light transmission and mass tone colors
· Disperses
to nano-size particles
Summary
Form:
BurnEx A1582, BurnEx ADP480 and BurnEx ADP494 are powders made by
spray drying aqueous solutions of colloidal antimony pentoxide. These
grades are surface treated to aid dispersion to colloidal size. All are
free-flowing agglomerates about 10-40 microns in size.
Function:
BurnEx A1582, BurnEx ADP480 and BurnEx ADP494 act as synergists with
halogen flame retardants. The nano-sized antimony pentoxide allows
greater retention of the original physical properties in most systems.

Application
Handling and compounding:
Stable and non-settling dispersions are formed in solvents with gentle
mixing. Polymer solutions
can be blended with such dispersions and will yield transparent films
when dried. Epoxy resins can
be blended with ADP494 dissolved in a ketone, and used to completely
impregnate a reinforcement and produce a transparent laminate.
ADP480 and ADP494 can be blended into ABS, HIPS and polypropylene in
compounding equipment such as a twin screw extruder. Since both ADP480 and ADP494 contain
some free and chemically bonded water, it is important that the
compounding equipment be vented.
In hot melt adhesive applications, some foaming may occur during
the initial melt blending. Contact Nyacol Nano Technologies, Inc. for
specific recommendations for compounding ADP480 and ADP494 in
thermoplastics.
