CLEVELAND, Nov. 15, 2012

CLEVELAND, Nov. 15, 2012 /PRNewswire-FirstCall/ --PolyOne Corporation (NYSE:
POL), a premier global provider of specialized polymer materials, services and
solutions, announced that DENSO Corporation, a leading supplier of automotive
systems for all major global automakers, has selected GLS OnFlex™
thermoplastic elastomer (TPE) for use in the heating, ventilation and air
conditioning (HVAC) system in a new car model. Working in close cooperation
with DENSO, PolyOne helped improve the in-service performance of the DENSO
HVAC system while also reducing total system cost.

"Like PolyOne, DENSO sets very high standards both internally and for its
suppliers," commented Holger Kronimus, vice president, Europe and general
manager, Specialty Engineered Materials, Europe at PolyOne. "Both companies
engage with customers globally, and are actively focused on continuous
improvement. We worked closely with DENSO to develop a specialized TPE
solution to satisfy DENSO's strict requirements."

For this application, DENSO originally used a thermoplastic vulcanizate (TPV)
and was seeking an alternative that would enhance the overall performance of
the system. In response, PolyOne developed a TPE solution that reduced the
total system cost by eliminating the need to pre-dry the material as well as
providing more than a five percent improvement in processing efficiencies via
shortened cycle times and scrap reductions. PolyOne was also able to meet
DENSO's strict specifications and provide consistent global supply, which was
critical to achieving success.

Director Masaki Shimizu, Head of Material Engineering Department, DENSO Corp.
Japan, noted his appreciation for the successful global cooperation between
DENSO and PolyOne. Christoph Wallner, Section Head, Material Engineering
Department, Technical Planning & Research DENSO Europe, explained, "The close
development cooperation with PolyOne enabled DENSO to significantly improve
its HVAC systems. Further, switching to the new polymer solution from PolyOne
helped DENSO to improve its manufacturing efficiency. Transferring this
technology to subsidiaries in other regions is already under consideration."

"This is an excellent example of how our values of collaboration, innovation
and excellence are driving meaningful increases in end use performance and
profitability for global industry leaders such as DENSO," added Mr. Kronimus.
