What is EPP foam?

Expanded Polypropylene (EPP) is a highly versatile closed-cell bead foam that provides a unique range of properties, including outstanding energy absorption, multiple impact resistance, thermal insulation, buoyancy, water and chemical resistance, exceptionally high strength to weight ratio and 100% recyclability.

How do you make a hot wire foam cutter?

Heat a wire cutter to cut through the foam. Plug in a small wire cutter until the wire is hot. Avoid touching the wire. Push the foam through the blade to make straight, smooth cuts. If you’d like to cut more details (such as waves, curvy lines, or circles), consider using a hot wire foam cutting table.
