PlatSil® SiliFoam is a two-part, platinum-cured silicone casting foam. This flexible foam has a free-rise density of 15 lb/ft³. SiliFoam can be used for many applications, but is often used in conjunction with PlatSil® Gel Silicone Rubber to create prosthetic appliances. The weight of large prosthetic appliances can be reduced by back-filling surface layers of PlatSil® Gels with low-density SiliFoam. Comes in a 6.7kg kit.
