A key attribute of all our products is the nano particle size, expressed as nanometers, millimicrons or billionths of a meter. This fine size plays an important role in our products' ability to be used in such a wide variety of applications.
Below is a description of key application areas and the NYACOL® materials used in each area. Specific information on the individual product grades is available in the Product Information section.
We invite you to contact us for further information or to discuss your requirements with our technical staff. The experience we've attained over years of technical service is easily available to you, and we hope you will take advantage of it.
Textiles
Nyacol offers NYACOL®
colloidal antimony pentoxide as a
fine particle dispersion for use as a flame retardant synergist with
halogenated flame retardants.
The dispersions offer the advantages noted below compared to
conventional antimony trioxide systems. NYACOL® colloidal
antimony pentoxide is offered as water dispersions, organic dispersions,
powders and polymer concentrates.
The choice of product will depend on the application and desired properties. Please refer to the Product
Information bulletins or contact our Technical Specialists.

Plastics
Nyacol offers NYACOL®
colloidal antimony pentoxide as
powders, organic dispersions, and polymer concentrates for use as a flame
retardant synergist with halogenated compounds in flame retardant
plastics. The ultrafine
particle size allows the formulator to achieve several advantages compared
to the micron-sized antimony trioxide. Translucent flame retardant articles can be produced
using colloidal antimony pentoxide powders, organic dispersions or
polymer concentrates.
Colorant loadings can be reduced one-third to one-half the normal
amount used with the pigment-sized antimony trioxide, resulting in lower
formulation costs and improved physical properties. Color matching is made easier as
a result of working with a low tint base polymer. Physical properties such as
impact strength are dramatically improved by use of the 0.03 micron
antimony pentoxide compared to micron-sized particles. The balance of properties
of the plastic is improved, allowing greater flexibility for the formulator. The ultrafine particle size also
allows the production of flame retardant thin films and flame retardant
fine denier fibers and monofilament. The small particle size also does not deluster the
fibers, allowing production of flame retardant bright fibers.
NYACOL® antimony
pentoxide products find use in PVC, polypropylene, polyethylene and ABS
plastics.
Nyacol also offers NYACOL®
colloidal zinc oxide as a UV
absorber and acid scavenger on a developmental basis for polymer
applications. The colloidal
zinc oxide is optically transparent but UV absorbing and is useful in
films, fibers and injection molded articles.
Electronics
Nyacol offers NYACOL®
antimony pentoxide powders for
use as a synergist with halogenated flame retardants in high performance
epoxy. Antimony pentoxide
has strong sorption properties for metallic impurities resulting in
improved long term performance of the epoxy in electronic
applications. Antimony
pentoxide is also less soluble than antimony trioxide and will not
interfere with electroless plating baths. The powders are also non-pigmenting for light
transmission and allow formulation of deep colors and the use of reduced
color loadings where applicable.
Films
Nyacol offers nano-sized NYACOL®
colloidal silica dispersed in
ethylene glycol for use in PET films and fibers. A range of particle sizes from 20
nanometers to 100 nanometers is available. These specialized products are manufactured in polymer
grade ethylene glycol and provide transparent antiblock properties in the
films and improved abrasion resistance.
Oil Refining
Nyacol provides NYACOL®
water-based metal passivation
additives based on antimony pentoxide or tin oxide. Antimony-based additives scavenge
nickel from the FCC catalyst, improving gasoline yields and reducing
catalyst attrition. Tin
oxide-based additives scavenge vanadium and extend the useful life of the
catalyst in FCC unit operations. NYACOL® metal passivation additives are easily
introduced into the FCC unit feed stream and can be diluted to required
concentrations easily. They
are extremely stable and only a small metering pump is required to
control dosage in the FCC unit.
Coatings
NYACOL® colloidal
alumina finds use as a high temperature coating and binder.
NYACOL® colloidal
tin oxide can be used as an anti-scuff coating on glass.
NYACOL® colloidal
zinc oxide is available on a developmental basis and can be used to
formulate optically transparent UV absorbing coatings on glass and other
substrates.
Ceramics
Nyacol offers a number of
colloidal dispersions or sols for use in ceramic applications. All the products are available as
highly stable dispersions for ease of use and handling.
NYACOL® colloidal
cerium oxide has demonstrated its effectiveness as a zirconium stabilizer
in ceramic applications.
NYACOL® colloidal
tin oxide is designed for use as a binder in ceramic or catalyst
applications.
NYACOL® colloidal
yttria is designed for use as a sintering aid for silicon nitride and
other ceramics, as a stabilizer for zirconia ceramics, for producing a
transformation toughened alumina ceramic, as a high temperature binder
for ceramics and fibers and as a core wash for titanium investment
casting.
NYACOL® colloidal
zirconia sols are available in a range of sizes for use as a binder in
investment casting of reactive metals and superalloys. The products can be used with or
without yttria depending on the application needs.
