Trinseo Inaugurates State-of-the-Art S-SBR Pilot Plant and Capacity Expansion of 50 KT in Schkopau, Germany

February 28, 2018

Company accelerates innovation in performance tire market

HORGEN, Switzerland–(BUSINESS WIRE)–$TSE #tires—Trinseo,
a global materials solutions provider and manufacturer of plastics,
latex binders and synthetic rubber, today marked the opening of its new
pilot plant and Solution-Styrene Butadiene Rubber (S-SBR) capacity
expansion at Schkopau, Germany. Business leaders and dignitaries, among
them Dr. Reiner Haseloff, Minister-President of Saxony-Anhalt,
celebrated the opening, marking an important milestone for both Trinseo
and the region of Saxony-Anhalt.

The corporation’s decision to open the new facility is triggered by the
growth in global demand for S-SBR and by the need for faster innovation
cycles in the performance tire market. The new pilot plant will design
next generation material and deliver sufficient quantities of new S-SBR
formulations as required for real-life tire-testing. The pilot plant’s
ability to evaluate both process and product parameters meet the tire
manufacturers’ need for reducing product validation time.

The production expansion adds additional 50 KT of S-SBR capacity to the
Schkopau site and increases the company’s global S-SBR production by 33
percent. Most of Trinseo’s production goes into the tire industry, and
the company has adopted the tire industry’s speed, innovation,
reliability and forward-looking-approach.

“With this plant, Trinseo has the ability to react faster to customer
demands and enable them to become technological leaders,” said Hayati
Yarkadas, Trinseo’s Senior Vice President and Business President. “The
new pilot plant and capacity expansion is consistent with our goal of
increasing EBITDA by $100 million in our Latex Binders, Synthetic
Rubber, and Performance Plastics segments from 2016 to 2019 businesses.”

Strong local commitment

The plant, with more than 500 staff members, is an important employer
and economic factor in Saxony-Anhalt that has a strong focus on research
and innovation. Trinseo is committed to maintaining this strong local
presence and will continue to invest in the region in the future.

“I am particularly pleased about Trinseo's commitment to research and
development. Innovations are the basis for further growth, which we
urgently need to continue the positive economic development in
Saxony-Anhalt,” confirmed Minister-President Dr. Reiner Haseloff.
