Kuraray Extends Commitment to AspenTech's Engineering Solutions for Optimization of Polymer Production Processes

Leading Japanese manufacturer uses Aspen Engineering Suite(TM) solutions to reduce time-to-market and improve quality and efficiency at its global production sites

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sept. 4, 2003--Aspen Technology, Inc. (Nasdaq: AZPN) today announced that Kuraray Co., Ltd, a leading Japanese polymer manufacturer, has extended its commitment to the Aspen Engineering Suite (AES)(TM) solutions with a new multi-year license agreement. Kuraray will expand the use of AspenTech's process modeling and optimization technologies at its global production sites, enabling the company to reduce time-to-market and improve the quality and efficiency of its production processes.

Kuraray is a global supplier of ethylene vinyl alcohol (EVOH), polyvinyl alcohol (PVA), polymethyl methacrylate (PMMA), functional polymer and man-made leather from its plants in Japan, USA and Europe. The company has been utilizing Aspen Engineering Suite solutions since 1999, and has used the technology to significantly enhance its process development capability. Notable benefits have been achieved with the application of the AES Polymers Plus(R) process modeling solution, which has enabled the company to develop and optimize complex polymer manufacturing processes.

"Kuraray has standardized on AspenTech's engineering solutions as a strategic technology to help us achieve our goals of shortening time-to-market and improving the cost and quality performance of our processes," said Mr. Koichi Kushida, Senior Managing Director of Kuraray. "The enhanced modeling capability provided by Polymers Plus has increased our competitiveness by enabling us to identify optimal solutions at each stage of introducing a new process: in research and development, during process development and up to production in the plant."

By including AspenTech's engineering solutions as a key component of its polymer process development methodology, Kuraray has realized an extensive range of benefits. These include a significant reduction in process development time, increased production capacity, and accelerated new product development. When launching a new process, the solutions have also resulted in a reduced need for experimental data collections and plant measurements, ensured smooth scale-up and plant start-up, and helped the company obtain the target product on the first run.

The value of the solutions has been enhanced by close collaboration between Kuraray and polymer experts from AspenTech's AES services and development groups. For the past four years, Kuraray has based a number of engineers at AspenTech locations to work alongside specialists in the development of polymer process models.

"Polymer production processes are extremely complex and difficult to model," said David McQuillin, President and CEO of AspenTech. "The results achieved by Kuraray reflect the value that our Aspen Engineering Suite solutions can deliver, enabling polymer manufacturers to realize significant benefits throughout the lifecycle of their processes, from initial research through to full-scale production."

The Aspen Engineering Suite is an essential element of AspenTech's solutions for enterprise operations management (EOM) in the process industries. These integrated, enterprise-wide solutions combine engineering and manufacturing/supply chain technologies to help companies optimize the way they engineer and run their manufacturing and supply chain operations.
