Soundac® PU-D30 Two-component sandwich anti drumming for walls Description Soundac® PU-D30 is a two component polyurethane compound designed for use in constrained layer applications of steel and aluminium in non horizontal objects and walls. ® The Soundac PU-D30 viscoelastic damping layer is a specially formulated polyurethane polymer designed to produce, together with the steel construction and a steel sheet constraining layer, a final structure with very high loss factor over a wide temperature and frequency range. This dramatically reduces noise generated by vibrations in the structure. The PU-D30 is well suited and easy to combine with ® the Soundac AS sound absorbing foams. Application Soundac® PU-D30 is used in anti drumming of walls, non horizontal floors reduced vibration levels of steel structures and machines. Stock These materials are always on stock.
