Pyrosorb-S Class O Foam

Pyrosorb-S  is an open cell acoustic impregnated polyurethane foam originally developed as a safety critical foam. Acoustic performance is good and absorption co-efficients are typical for a cellular material, but unusually high deadening performance is attributable to the high density of approximately 85kg/m3. The high mass helps to reduce vibration in metal enclosures hence drumming and noise breakout.
