Midland, Michigan - Dow Polyurethanes has provided a polyurethane system to help develop lightweight Kio composite manhole covers that the company says are 70 percent lighter, yet just as secure, as traditional cast iron alternatives.
Kio is the result of a two-year development project between Dow and Industrie Polieco MPB, and the solution includes Dow's Voraforce fast cure LFI PU system. Polieco makes the composite and the covers, while Dow will help bring the product to market.
Dow said in a 10 Oct news release that when compared to traditional cast iron alternatives, Kio composite manhole covers "help to secure roads worldwide with the solidity and hardness of cast iron at 70 percent less weight, magnetic insulation, noise reduction, innate resistance to corrosion and 13-48 percent lower CO2 emissions." The composite can also be customised according to customers' needs.
"Kio is one brilliant example of what can be done. Polyurethane systems, with their features and versatility, are still far from demonstrating their full potential contribution in composite products. Dow and Polieco are continuing their work to bring further opportunities and expand the range of Kio into new grades and products," commented Francesca Pignagnoli, EMEA industrial composites market manager, Dow.
