2 lb Ethafoam

A registered trademark for a polyethylene foam plank. Ethafoam® is a durable, flexible, closed-cell foam that is waterproof and chemical resistant with an excellent memory. It performs consistently through a wide range of temperatures. It is easily cut with knives, hot knives, band saws, powered foam rubber cutters, and table saws. Ethafoam® adheres to itself and other polyethylene-based materials with heat-welding, or to most other surfaces with industrial-grade hot glue. The natural color of polyethylene foam is brilliant, sparkling white with a slight translucence in thin areas, but black and blue are also available in a limited range of sizes.
