Density of Duocel® Foam
Foam density - The actual density of a piece of foam is simply the bulk density of the base material of the struts or ligaments multiplied by the relative density.
Actual foam density = solid strut density × foam relative density
Typical foam relative densities:
Metal foams = ~2%min to ~ 15% max ( ~4% to ~ 10% typical useful range)
Carbon foams = 3% to 4% typical
Ceramic foams = ~3% min to ~20% max (~ 6% to ~ 12% typical useful range)
While foam products are always accompanied with material data including the relative density, the customer can easily reproduce or confirm this data. Simply weigh and measure the part, then divide the measured weight by the calculated weight if one were to assume the part were 100% solid material.
