Polyurethane Subsea Buoyancy Foam

LAST-A-FOAM® R-3300 BUOYANCY FOAM SERIES

LAST-A-FOAM® R-3300 is a closed-cell, hydrostatic pressure-resistant polyurethane foam that provides buoyancy to depths of up to 1,200 feet. It is typically supplied uncoated.

This semi-submersible foam is engineered to resist penetration by water, and is optimal for shallow to mid-water subsea buoyancy systems, marine and underwater robotics applications. Due to its pressure resistance to many fluids and resins, it is also used in resin-transfer molding as a core material.

Advantages
