01-Oct-09

The Dow Chemical Company will launch a portfolio of proven technologies for North American freight and passenger railway systems with it’s tailor-made polyurethane elastomer systems. By reinforcing ballast and controlling shock and vibration, Dow’s technologies help to increase railway service life, improve passenger safety and comfort, and reduce noise pollution. “Traditional concrete or ballast rail systems are prone to vertical and horizontal shifting, vibrations, corrosion and heaving. This can lead to track misalignment, stray electrical currents, unacceptable noise levels, passenger discomfort and safety concerns,” said David Frost, Business Development Leader, of Dow. “Dow polyurethane elastomers provide excellent track and ballast stability and noise absorption and are impervious to corrosion and moisture, helping to prolong track life and reduce maintenance and repair costs.”
