Reticulated Polyurethane

A Net-Like, Porous Foam

Reticulated polyurethane foam is a net-like, porous foam that is extremely versatile. While some foams are formed with a series of bubble-like cells, reticulated polyurethane foam has mainly open cells. Typically, 95-98% of cells are open in reticulated polyurethane foam. This open cell construction is valuable in a variety of applications and is especially useful in instances where liquids and/or air is required to be absorbed or filtered.
