Ethafoam is a strong, resilient, medium-density, closed-cell, white polyethylene foam which is acceptable for use in the preservation of historic objects. Sold in planks 1″, 2″, and 4″ thick, it is an ideal material to use to cushion and protect fragile items. Ethafoam is easy to cut into the appropriate shape for particular purposes, including displaying items, creating cushioned housings, lining drawers, or for protection during transportation. All Ethafoam planks are 24″ wide; full 108″ long planks must ship via truck. For your convenience we now offer half-length (54″) sheets, which can ship via UPS, as well as 12″ planks. We are happy to cut to specific sizes if you need us to do so, just let us know what lengths you need.
