General Plastics LAST-A-FOAM® R-3312 Submersible Foam Series
Categories:	Other Engineering Material; Composite Core Material
Material Notes:	Product Description: LAST-A-FOAM® R-3300 is an easy-to-machine, pressure-resistant foam that provides buoyancy for underwater depths tested to 2,400 feet, when coated. The closed-cell structure of this series is uniquely engineered to withstand penetration by water and resist hydrostatic pressure. LAST-A-FOAM® R-3300 submersible foam is optimal for shallow to mid-water subsea buoyancy systems, marine and underwater robotics applications. Features & Benefits: Provides buoyancy with depths to 1,200 feet uncoated and 2,400 feet coated Excellent mechanical and insulation properties Easy to machine, coat, and paint Dimensionally stable 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 and saltwater Compatible with many types of adhesives Applications: Underwater buoyancy Underwater robotics (ROV/AUV) Semi-submersible craft Pipeline flotation Subsea mooring buoyancy Buoyancy for assembly components in weightlessness simulation pools Underwater pumps for offshore drilling rigs Core material for resin-transfer molding Information provided by General Plastics Manufacturing Company
