It can also be cut cleanly with water jets and traditional wood-carving tools. Modeling foam is available in densities of 4 to 40 lbs. per cubic ft. as sheet stock as well as large-size blocks. The FR-7100 Series is ideal for applications that call for an economical, versatile and stable stock material.
