Corning Introduces Next-Generation Ceramic Substrate For Light-Duty Vehicles

Corning Incorporated (NYSE:GLW) today announced the introduction
of the Celcor(R) 600/2 substrate, a next-generation ceramic substrate
for light-duty gasoline and diesel-powered vehicles. With its
ultrathin walls, the new substrate enables reduced fuel consumption
and increased engine power through low exhaust system back pressure.

The Celcor 600/2 product is designed with six hundred cells per
square inch and walls that are two mils thin - about the width of a
strand of human hair. This cell geometry results in an extremely
light-weight ceramic substrate that provides excellent cold-start
emission reduction benefits. Corning began manufacturing and supplying
the Celcor 600/2 substrate in the third quarter of 2007 for inclusion
in 2008 model-year vehicles.

"Corning is pleased to introduce an advanced ceramic substrate
that can reduce overall system cost, optimize performance through low
back pressure, and offer increased design options for vehicle
manufacturers," said Thomas Appelt, vice president and general
manager, Automotive Technologies, Corning Incorporated. "We leveraged
our expertise in materials, product design and manufacturing to
develop an innovative ceramic substrate with improved attributes. We
will continue to research, develop and design next-generation
substrates that help our customers achieve greater system
optimization."

Corning's innovation leadership has enabled the company to
continually advance ceramic substrates and diesel particulate filters
to meet the most demanding global emissions requirements. Corning
substrates and filters are available in a wide variety of lengths,
contours, and cell densities, enabling more design options for on-road
and non-road engine and vehicle manufacturers.

Corning is a leading supplier of advanced ceramic substrates and
diesel particulate filters for all of the world's major manufacturers
of gasoline and diesel engines and vehicles. The company invented an
economical, high-performance ceramic substrate in the early 1970s that
is now the standard for catalytic converters worldwide. In 1978,
Corning developed the cellular ceramic particulate filter to remove
soot from diesel emissions.
