Subsea Buoyancy Foam for use on ROVs, AUVs, and other marine robotics applications. This foam can be machined, glued, painted, and coated to build any size or shape of float that you want.

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.
