LAST-A-FOAM® R-3300 Buoyancy Foam Series

LAST-A-FOAM® R-3300 is a machinable, hydrostatic pressure-resistant buyoancy foam that provides buoyancy underwater (to depths of 1,200 ft., uncoated or 2,400 ft. coated), offering outstanding resistance to penetration by water. Due to its hydrostatic pressure-resistance to many fluids and resins, it is also used in resin-transfer molding as a core material. LAST-A-FOAM® R-3300 submersible foam is optimal for shallow to mid-depth underwater robotics applications.

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

Advantages:

  • Easy to machine and paint
  • Depths to 1,200 ft uncoated or 2,400 ft. coated
  • Dimensionally stable
  • Inert
  • Will perform in freshwater or saltwater

Applications:

  • Underwater buyoancy
  • Underwater robotics (ROV/AUV)
  • Semi-deep submersible crafts
  • Pipeline Flotation
  • Subsea moving buoyancy
  • Buyoancy for assembly composites in weightlessness simulation pools
  • Underwater pumps for offshore drilling rigs
  • Core material for resin-transfer molding
