Cologne, Germany - Orsa Foam SpA used Interzum, a trade show for the global furniture industry, to launch a new range of highly air-permeable foams.
Designated Breeze, the foams are available as high resilience and viscoelastic versions. The standard density certificated foams have permeability to ISO 7231 of between 2.5 and 2.0 dm3/s which is around 40 times greater than HR foam and 8x greater than viscoelastic foam.
Normally such permeabilty is produced by secondary reticulation, said Andrea Cirani, R&D manager at Orsa. The new formulations do not need the secondary step. In addition, the foams retain their initial stiffness, when in contact with moisture for extended periods. Criani explained that this is important if a comfortable night's sleep is needed.
The Breeze HR foam has comparable dynamic fatigue properties with Orsa's equivalent density HR foams. Criani declined to give formulation details.
