US: CPS Performance Materials has acquired Handy Chemical USA from Rain Industries. The two napthalene sulphonates producers are the only domestic suppliers of the dispersant to the gypsum wallboard industry in the entire North American region, according to Barney Heller, Hardt Chemical. The transaction concentrates napthalene sulphonates supply under single ownership in the region. The sale, which also included Rutgers Polymers, is valued at around US$87m.
Naphthalene sulphonates are produced using napthalene from the steel industry. Their use in gypsum wallboard production reduces the necessary water content, improving slurry stability, increasing line speed and strengthening the final product. Steel-producing countries such as China have previously exported napthalene sulphonates to the US. The market for gypsum wallboard in North America is estimated to be 45,000t/yr.
