AlumiFoam is a 2 part structural foam that provides users with a good skin and an extremely hard, durable, 20 lb density structural foam. AlumiFoam expands 3-5 times the original liquid volume and produces an extremely hard, dense, and durable cast piece with good detail. AlumiFoam is great for casting light weight fishing lures that require great buoyancy and extreme durability. AlumiFoam is also great for structural reinforcement, rotational molding, and as an accurate replacement for the weight and feel of wood.
