DuPont Launches Hybrid Membrane Technology for Global Industrial Filters Market

New Innovation Significantly Reduces Particulate Emissions and Saves Energy

WILMINGTON, Del., April 17 /PRNewswire-FirstCall/ -- DuPont (NYSE: DD)
today announced the global availability of its Hybrid Membrane Technology
(HMT) fiber in air filtration bag applications for industrial and commercial
manufacturing. The product rollout has begun in the United States and Europe
with availability through DuPont's laminator network.
"DuPont HMT is a product with a unique offering and significant benefits
for manufacturers in every region," said Thomas G. Powell, vice president and
general manager -- DuPont Advanced Fiber Systems. "Our customers now have a
product that increases cycle time up to nine times over the incumbent
polyester felt, with an improvement in energy efficiency. More importantly,
these fibers, only available through our Hybrid Membrane Technology, capture
up to 10 to 15 times more dust and particulates in the air compared to
incumbents, providing a cleaner environment for workers and consumers inside
and outside manufacturing facilities."
Referred to as "dust collection bags" in the industry, these filtration
products are used with exit air to capture particles so they are not emitted
to the environment -- an increasingly important need as more countries enact
regulations for cleaner air. The incumbent polyester felt bags are commonly
used at any production facility that generates particulates and dust from
wood, cement, asphalt, paint, minerals and powders, among others. HMT fiber
bags provide air flow with an improved cycle time and better capture of
particulates. Initial DuPont data, based on industry testing standards, shows
that HMT technology provides energy savings by reducing down time and
providing more consistent pressure levels.
DuPont estimates the global air filtration market at more than $1 billion,
with the dust collection segment alone at $300 million.
HMT is a DuPont innovation based on nanofiber science. It is produced by
DuPont in Seoul, Korea, using a proprietary spinning process that produces
continuous filaments with diameters between 200 and 600 nanometers. DuPont
Hybrid Membrane Technology provides better performance versus the incumbent
materials across a variety of air and liquid filtration applications where
energy efficiency and reduction of particulate contamination and emissions are
critical. It adds breathability and protection to bedding products and
provides a unique offering for energy storage, where it can significantly
improve the safety, durability, power and energy performance in a variety of
capacitor and battery applications.
DuPont conducts customer application testing at its sites in Wilmington,
Del.; Richmond, Va.; Geneva, Switzerland and Seoul, Korea. DuPont sells HMT
in rolls to laminators, who then sell the completed product to "bag"
manufacturers.
DuPont HMT is a product offering of the DuPont Safety & Protection
segment, which includes DuPont Building Innovations, DuPont Advanced Fiber
Systems, DuPont Nonwovens, DuPont Chemical Solutions Enterprise and DuPont
Safety Resources. The segment provides innovative products and services that
protect people, buildings, critical processes and the environment. In 2007,
the segment's revenues totaled $5.6 billion.
DuPont -- one of the first companies to publicly establish environmental
goals 18 years ago -- has broadened its sustainability commitments beyond
internal footprint reduction to include market-driven targets for both revenue
and research and development investment like Hybrid Membrane Technology. The
goals are tied directly to business growth, specifically to the development of
safer and environmentally improved new products for key global markets.
DuPont is a science-based products and services company. Founded in 1802,
DuPont puts science to work by creating sustainable solutions essential to a
better, safer, healthier life for people everywhere. Operating in more than
70 countries, DuPont offers a wide range of innovative products and services
for markets including agriculture and food; building and construction;
communications; and transportation.
