Arsenal Capital Partners has purchased RTH Processing, which produces material for track and playground surfaces, along with sister company RDT Manufacturing.
Private equity firm Arsenal Capital Partners has bought related plastics and rubber firms RTH Processing and RDT Manufacturing, marking the 11th plastics-related investment that Arsenal has made in less than three years.
RTH and RDT both operate from a single plant in Delphos, Ohio. RTH claims to be the largest U.S. maker of colored EPDM granules, which are used in playground surfacing, running tracks and similar surfaces along with polyurethane binders. RDT makes rolled rubber products and tiles — such as athletic and commercial flooring — from recycled materials.
No purchase price was disclosed in a May 6 news release announcing the deal. The acquisition was made by Accella Performance Materials Inc., a unit of New York-based Arsenal that previously was known as Dash Multi-Corp. Inc.
RTH and RDT now will be combined into a single firm as Ultimate RB Inc.
In the release, Accella CEO Andy Harris said that the deal will bring expanded capabilities and colored EPDM technology to Accella’s recycled rubber products business, The acquisition also will allow for “tremendous cross-selling opportunities” with the firm’s polyurethane business in the athletic surfacing market.
Arsenal bought six plastics-related businesses in 2012 and added four more in 2013. Most recently, the firm in August bought cellulose and plastic fiber maker International Fiber Corp. of North Tonawanda, N.Y., for an undisclosed price. |
