Hydrostatic Pressure Resistant Foam

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

LAST-A-FOAM® R-3300 is a hydrostatic pressure-resistant foam formulation that provides buoyancy for underwater flotation applications. It offers outstanding resistance to penetration by water and other liquids. It is available in densities of 15 lbs./cubic foot (depth to 650ft) and 18 lbs./cubic foot (depth to 775ft). These submersible polyurethane foams are capable of providing permanent flotation in semi-deep submersible craft, and similar applications. They are also used in resin-transfer molding as a core material.

This high-density urethane supports training operations for the International Space Station, providing flotation for assembly components in pools that simulate weightlessness.

AdvantagesApplications
  • Up to 350 psi resistance to liquid penetration
  • CNC machinable
  • Depths to 775 ft.
  • Underwater flotation
  • Core material for resin-transfer molding
