ST. LOUIS, May 6, 2014 /PRNewswire/ — Accella Performance Materials, Inc. (rebranded from Dash Multi-Corp, Inc.) a leading manufacturer of polyurethanes, plastisols and recycled rubber products, has announced the acquisition of two related companies, RTH Processing, Inc. and RDT Manufacturing LLC (aka Ultimate) to form the new company Ultimate RB, Inc. Accella Performance Materials (“Accella”) is a platform portfolio company of Arsenal Capital Partners (“Arsenal”) who focus on investing in and growing specialty industrial companies.

Both companies operate out of a single manufacturing facility in Delphos, Ohio.
“RTH Processing and RDT Manufacturing represent ideal additions to the Accella Performance Materials platform,” said Accella CEO, Andy Harris. “In addition to bringing expanded capabilities and colored EPDM technology to our recycled rubber products business, they will allow for tremendous cross-selling opportunities with our polyurethane business in the athletic surfacing market. With the combination of RTH Processing, RDT Manufacturing and Accella’s RB Rubber, we are now the only manufacturer in the world that offers complete ‘custom’ systems encompassing all of the components of playground surfacing and running tracks. The Ultimate RB combination will bring the greatest value, service and support to our customers.”
“From a strategic standpoint the combination of RTH and RDT with our RB Rubber recycled rubber business puts us in a uniquely competitive position to provide great value to our customers. We become the only manufacturer that is fully vertically integrated, as we now produce our own recycled tire crumb, wide variety of colored EPDM granules and urethane binder. We have the most diverse product line in the industry, and we are the only manufacturer with multiple production sites across the United States. The Ultimate RB combination will allow us to offer unrivaled quality and value to our customers,” added Accella Vice President of Recycled Rubber Products, Hal Stuhl.
Ted Horstman, President of RTH and RDT said, “We are excited about the Accella partnership and the merger of the rubber companies which positions us to better serve our customers globally and to expand our product offerings into existing and new markets. The companies are highly complementary and both become better through the combination as the market leader.” Ted added, “The contributions of our employees were invaluable in making RTH and RDT the success they are today, and I am pleased the new combination will provide our employees even greater opportunities for a very bright future.”
John Televantos, a Partner at Arsenal Capital Partners and co-head of the firm’s Specialty Industrials Group, said, “RTH Processing and RDT Manufacturing have a long history of innovation in the custom colored EPDM and recycled rubber market that fits very well with Accella’s history and culture. The custom color compounding technology continues to evolve and address unmet needs in the market. As we expand the Accella recycled rubber and polyurethane systems businesses, this will help support our customers in their growth.” Tim Zappala, a Partner at Arsenal Capital Partners and co-head of the firm’s Specialty Industrials Group, added, “The combination builds on our strategy to create technology-based businesses that are market leaders offering a differentiated portfolio of products that uniquely serve multiple end markets.”
