NYACOL®
COLLOIDAL ANTIMONY OXIDE
Flame
Retardant Powder
NYACOL®
BurnEx™ 6220 has been
developed as a flame retardant synergist for ABS,
polyolefins and other materials employing halogens
as the primary flame retardant. Color pigment loading
can often be reduced by 50% when antimony trioxide
is replaced by an equal weight of BurnEx™ 6220.
The brilliance of fluorescent colors is easily maintained
and translucency retained. In pastel shades the
use of titanium dioxide as a white pigment together
with BurnEx™ 6220 for flame retardancy is preferable
for reproducible color matching.
Form
BurnEx™ 6220 is manufactured
by spray-drying colloidal antimony oxide from a
water dispersion of 0.03 micron particles. The spray-dried
powder is composed of agglomerated particles in
the range of 0.5 to 2 microns. BurnEx™ 6220
is a free-flowing powder that does not require grinding
to eliminate white specks.
Advantages
BurnEx™ 6220 provides the
following advantages over antimony trioxide:

color pigment loading by 50%
