Alumilite’s Flexible Foam 5-8lb Density is an easy to use, versatile, high tear strength, 2 part expandable flexible foam. It’s ideal for making soft foam pieces and also is great for prototyping or casting cushions, vibration dampeners, or flexible nests/fixtures.
Once mixed, the 2 parts will chemically react and begin to expand before curing into a 3-5 lb density flexible foam in open molds or a 5-8 lb density foam in closed molds.
