PolyOne to Feature New Advancements in Color Technology, Nanocomposites and Inherently Conductive Polymers at National Plastics Expo 2003

May 29, 2003

New technology developments, core capabilities and PolyOne Distribution
highlighted at Booth 1832

CLEVELAND, May 29 /PRNewswire-FirstCall/ --
PolyOne Corporation (NYSE: POL) will feature several new technologies at next
month's National Plastics Expo (NPE), including advancements in color
technology, nanocomposites and inherently conductive polymers (ICPs). PolyOne
will be in Booth 1832, South Building at Chicago's McCormick Place for the
show, which runs June 23-27, 2003.

PolyOne will introduce a new family of nanoclay-based polymer concentrates
at NPE. This new nanocomposite capability is a result of a previously
announced strategic alliance with Nanocor. The technology, which uses very
fine nanoclays that are roughly 1/10,000th the diameter of a human hair,
principally improves stiffness, fire resistance and gas barrier at lower
weight than traditional additives. Nanocomposites also promote greater heat
stability and electrical dissipation. Primary markets include automotive,
appliance and film.

In addition, PolyOne will introduce its new color technology capabilities
with special live demonstrations in a dedicated viewing theater at the booth.
The new color technology offering is designed to shorten the color matching
process and allow color standard data to be stored electronically compared to
a traditional plastic chip. The technology will also allow customers to model
a three-dimensional product in a variety of virtual environments, for example
a shampoo bottle in a pharmacy, and then see with a high degree of realism
what the color will actually look like.

Also featured are inherently conductive polymers (ICPs), which have
similar electrical conductivity properties to metals and inorganic
semiconductors, but are lighter, easier to process and more environmentally
friendly. ICPs can be used in corrosion-resistant coatings, anti-static
fabrics and packaging, EMI/RFI shielding, and electronic products.

"NPE is a great opportunity to talk with our customers about the breadth
of our core capabilities as well as showcase many of our new technologies --
platforms that are important to our future growth," said Thomas A. Waltermire,
chairman and chief executive officer of PolyOne. "Our new products will be
especially important to global customers because of PolyOne's unique
capability to help them reach their customers around the world."

PolyOne will also highlight several products and technologies from its
Engineered Materials group including:

  • Ecomass(R) high-gravity thermoplastic compounds
  • Therma-Tech(TM) compounds, which readily conduct heat at levels more
    than 100 times that of standard plastics
  • Electrostatic dissipative (ESD) compounds
  • Thermoplastic elastomer (TPE)-based products, which are used in a
    variety of markets including automotive interiors, consumer products,
    seals and gaskets, and recreational products.

The PolyOne booth will be divided into three areas:

  • New developments: This area will highlight PolyOne's advanced
    technology and product growth platforms, including nanocomposites,
    color technology and ICPs.
  • Core capabilities: The breadth of PolyOne's products and services in
    Vinyl Compounds, Engineered Materials, and Color and Additive
    Masterbatches will be showcased here.
  • PolyOne Distribution: This section will focus on the more than 15
    leading suppliers, global sourcing capabilities, and advanced supply
    chain management and logistics services offered by the Company's
    distribution business.

PolyOne Corporation (NYSE: POL), with 2002 revenues of $2.5 billion, is an
international polymer services company with operations in thermoplastic
compounds, specialty resins, specialty polymer formulations, engineered films,
