Berwyn-based Trinseo/Styron, a global manufacturer of plastics, latex and rubber, recently reported revenues down by 3 percent for 2013, but growth within its international companies.

Trinseo/Styron’s technology is used in home appliances, and in the automotive, construction, carpet, consumer electronics, consumer goods, electrical and lighting, medical, packaging, paper and paperboard, rubber goods and tire industries.

The company attributes the overall decrease in sales volume in part to latex raw material increases, expansion of its synthetic rubber business, and lower butadiene costs in latex and synthetic rubber.

Trinseo/Styron had approximately $5.3 billion in revenue in 2013. The company has 19 manufacturing sites around the world, and approximately 2,100 employees. Trinseo/Styron is expanding its latex production in Zhangjiagang, China, and upping rubber production in Schkopau, Germany.

“Full year 2013 Adjusted EBITDA, excluding inventory revaluation of $344 million is the highest fiscal year in Trinseo’s history, looking back to 2011,” Chris Pappas, Trinseo president and chief executive officer, said in a news release.

”I am proud of our full year results and other achievements that have improved the company’s growth prospects for the future,” he said. “Our team remains focused on executing our business strategies and I am cautiously optimistic for a better 2014.”

The company previously announced plans to change the name of all Styron-affiliated companies to Trinseo. Styron companies that have not yet changed their names are continuing to do business as Styron until their name changes are complete. Styron’s operating companies also continue to operate under the Styron name.
