Emerald Specialty Polymers, a business group of Emerald Performance Materials, has introduced Nychem 1561X604, a new nitrile latex emulsion designed to optimize
strength, abrasion resistance, chemical
resistance and other performance characteristics in paper saturation, textile
coating and gasket applications.
Nychem 1561X604 is a medium-nitrile-level specialty emulsion that improves upon the performance of previous
generation polymers, greatly enhancing
tensile strength and providing superior
resistance to water, oil, grease and hydrocarbons. The advanced technology
behind Nychem 1561X604—based on
butadiene, acrylonitrile and styrene—
also provides benefits such as high elongation and abrasion resistance. Designed
with low/no emulsifier levels, Nychem
1561X604 is a high surface tension emulsion that exhibits low foam.
“We created Nychem 1561X604 by
working closely with our customers to
design a superior polymer that would
optimize toughness for particular use
in paper and textile applications. The
result is an emulsion that has exceeded
even our expectations. Tensile strength
was increased by 400 percent, while
maintaining the high elongation over the
starting latex in paper testing prior to
any crosslinking or vulcanization of the
acrylonitrile-butadiene-styrene lattices,”
said Jeffrey Mathys, R&D Manager for
Emerald Specialty Polymers. “Not only
is the performance phenomenal, but be-
cause 1561X604 utilizes a vulcanizable
resin, there is an opportunity to tailor the
product for even further toughness.”
Mathys noted that physical proper-
ties of Nychem 1561X604 rubber films
demonstrated results similar to those of
paper products. Development of the new
product occurred at Emerald’s pilot plant
in Akron, Ohio, which was completed in
December 2013
“We commissioned the pilot plant to
expand the flexibility and R&D capa-
bilities of the nitrile operation. Since its
completion, we have explored a great-
er range of end-use applications and
looked at how we can develop unique
solutions that optimize performance
and overcome traditional formulation
challenges for those applications,” said
John Zuppo, vice president, commercial
services for Emerald Specialty Polymers.
DuPont Introduces Water-
based, Low-VOC Coating
Solution Based on Teflon
PTFE
DuPont has developed a new water-based, low-VOC coating solution based
on Teflon PTFE for fasteners in highly
corrosive environments. This easy to
handle one-coat system is particularly
suitable for applications requiring very
high corrosion resistance, dry lubrication
and anti-seize properties to prevent galling, the copany said. Typical applications
are screws and bolts made from substrates such as carbon steel, special steel
and aluminium used in offshore oil and
gas extraction, the chemicals industry or
in water treatment plants. Results from a
salt spray test according to ASTM B117
carried by an independent laboratory
have confirmed that screws treated with
this new coating solution have outstanding corrosion resistance even without surface pretreatment. Corrosion resistance
can be further improved by using suitable
primers or substrate pretreatments.
Sunin Introduces New
Ceramic Horizontal
Grinding Mill
Sunin Machine Co. has introduced a new
ceramic horizontal grinding mill. This
new mill is capable of grinding materials
at the nanometer level.
It features a double-set mechanical
shaft seal, front open, slit ranged from
0.1-0.2mm. The tank can be made of different materials.
It is also capable of grinding beads,
non-pollution, non-leakage, non-conductive to magnetic, cosmetic, fine ceramic,
Li-materials, electric IC materials and
non-conductive to electricity.
Ethox Chemicals Announces
New Patents
There is a large and growing use for latex
coatings and the emulsion polymerization process used to manufacture them.
Ethox Chemicals has announced the recent issuance of a patent covering important improvements to this process.
The US patent number 9,023,943
and its related patent 8,067,513, teach
the use of certain styrenated phenol
ethoxylate surfactants to improve the
emulsion polymerization process. The
end-user will see a smaller particle
size, tighter particle size distribution,
good freeze-thaw stability, excellent
mechanical and chemical stability,
lower coagulum, and lower foaming.
These benefits provide better quality
latexes which in turn, provide better
quality coatings.
Ethox enables you to benefit from
this technology by their development
of several new surfactants within their
E-Sperse line of coating products. The
anionic products include E-Sperse 100,
E-Sperse 701, E-Sperse 702, E-Sperse
704, and E-Sperse 705. The nonionic
products are E-Sperse 700 and E-Sperse
703. These products are effective pigment dispersants as well. Testing showed
that there may be synergies obtained
when using these products in combination for both the pigment dispersion and
the emulsion polymer.
“There has been a growing need in the
industry to produce higher quality latex
coatings,” said Dr. Chip Palmer, VP of
Technical for Ethox Chemicals. “Ethox
was able to create a new process and introduce a number of products to the market that will help coating manufacturers
develop new and better products.” CW
