Product Description

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 particular size is machined to fit perfectly into the BlueROV2 fairing and maximize the amount of available buoyancy. Upgrading to this machine foam adds a total of 500 grams (1 lb) of additional buoyancy. This adds more stability and payload capacity to the ROV.

Rated to 300 meters operation depth when uncoated.

Features

  • Easy to machine, coat, and paint
  • Excellent compressive and insulation properties
  • Resistant to hydrostatic pressure
  • High impact resistance
  • Biologically Inert
  • Oil, grease, and solvent resistant
  • Cost-effective solution
  • Does not rot or decay
  • Performs in freshwater or saltwater
  • Compatible with many types of adhesive
