Sub-sea pipeline insulation and field-jointing without mercury catalysts

31-Jul-08
Dow Hyperlast continues to respond to both environmental concerns and major flowline thermal-loss prevention advancements, with the introduction of a comprehensive range of pipeline insulation and field joint systems, that incorporate polymer and glass syntactic with solid polyurethane elastomers for use in water depths of up to 3,000 metres (10,000 ft). The latest systems differ from the previous formulations in that a mercury catalyst is no longer utilized. The recently introduced HYPERLAST™ Low Density Syntactic Polyurethane is only available without a mercury catalyst, whilst the remainder of the Dow Hyperlast range of sub-sea products are now presented with the option of non-mercury catalysts without any loss of performance to their exceptional physical and chemical properties or to their excellent hydrolytic resistance. Development of deep-water oil and gas production is increasing and Dow Hyperlast is one of the leaders of developing materials and technology that help to improve flowline design, reduce thermal loss and value the environment. Dow Hyperlast is part of Dow Polyurethane (PU) Systems, a business group of The Dow Chemical Company and its subsidiaries, and a leading developer of polyurethane materials. Company Press Release
