Dow Chemical Co. has vowed to cut its use of mercury in the catalysis of polyurethane elastomers. The firm's Dow Formulated Systems business unit plans to launch a new line of Hyperlast and Diprane elastomers.
The Birch Vale, UK, business unit will use previously successful polymer backbones with enhanced improvements in material processing and final properties. Dow will introduce the newly catalysed elastomers at Utech Europe 20102 to be held in Maastrict, the Netherlands in April 17-19.
Dow aims to comply with restrictions for five phenylmercury substances under Regulation EC No. 2907/2006, commonly called REACH Regulations in Europe.
By avoiding implications of REACH regulations Dow wants to ensure supply longevity of the elastomer families. Dow has already reformulated its one-pack elastomer Monothane polyurethane systems for REACH compliance.
