LAST-A-FOAM® R-3318 is a machinable, hydrostatic, pressure-resistant foam that provides buoyancy underwater. The closed-cell structure is engineered to resist penetration by water. Due to its pressure resistance to many fluids and resins, it is also used in resin-transfer molding as a core material. LAST-A-FOAM® R-3318 semi-submersible foam is optimal for shallow to mid-water underwater robotics applications.

This subsea polyurethane foam supports training operations for the International Space Station, providing buoyancy for assembly components in pools that simulate weightlessness.
