Soundac® PU-D20 Two-component sandwich anti drumming for floors Description Soundac® PU-D20 is a twocomponent polyurethane compound designed for use in constrained layer applications of steel and aluminium in horizontal objects and floors. ® The Soundac PU-D20 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. 6,7 kg A + 1,0 kg B The PU-D20 is well suited and easy to combine with ® the Soundac AS sound absorbing foams. Application Soundac® PU-D20 is used in anti drumming of horizontal floors and reduces vibration levels of steel structures and machines. Stock These materials are always on stock.
